In the world of watches, most true aficionados have a diver or two in their collections. Although they have been replaced by dive computers and most dive watches never see any water other than in a thunderstorm, their style, reliability, and rugged history make them appealing. 

I have never been more than one meter below the surface, yet, I own four divers. They are among the favorites in my collection. I feel like an adventurer on dry land, even sitting at my desk when I wear a dive watch. That includes the Seiko SSK001.

About The Seiko SSK001

The Seiko SSK001 is part of the Seiko Sport 5 GMT collection. It’s an automatic diver with a GMT complication that looks fantastic with casual, smart casual, or business attire. Released in the spring of 2022, The Seiko Sport 5 SSK01 is a durable, reliable, and beautiful GMT timepiece. Best of all, you can get it for less than $500. That’s not a typo.. Let’s take a closer look. 

History of Seiko GMT Watches

Seiko has a long and proud history that began in 1881 when Kintaro Hattori began selling and repairing clocks and watches at a shop in Tokyo. Under the brand name Seikosha, Hattori began making clocks in 1892 and pocket watches in 1895.

Hattori created his first wristwatch, the Laurel in 1913 and in 1924, changed his company’s name to Seiko, thus beginning a tradition that continues to this day. The Seiko brand kept improving and releasing new and innovative watches. By the 1960s, the brand was producing chronographs and dive watches.

In 1967, Seiko announced its arrival in the world of elite horology, taking second and third place in the final Neufchatel Observatory and Geneva Observatory Competition. Seiko made quite a splash in 2014 when the SBGJ005 Hi-beat 3600 GMT won the Petite Aiguille Award at the Grand Prix d’Horlogerie de Geneve. The long journey led to the 2022 release of the incredible and affordable Seiko SSK001. Timepieces of this caliber don’t appear overnight, folks. 

Seiko SSK001: In-Depth Review

There’s a lot to like about the Seiko SSK001, especially if you are a traveler or like to track multiple time zones and have a tight budget.

Case

The SSK001 features a 42.5 mm stainless steel brushed case with polished sides to make it stand out. This size suits many wrist sizes. Mine is an average 7.25 inches, and the SSK001 is right in the wheelhouse of my preferred case size. With a lug-to-lug width of 46 mm and a thickness of 13.6 mm, this watch wears well on smaller wrists.

If you’re a watch nerd like me, you’ll appreciate the exhibition case back, which allows you to get a good look at the movement. The crown is not screw-in, making this timepiece more of a desk diver. It sits at four o’clock rather than at three. Some people have trouble with the asymmetry, but I feel it adds character and unique charm to this timepiece.

Bezel

As a proper GMT watch, the SSK001 has a 24-hour bezel. The black and gray two-tone insert indicates day and night and it turns unidirectionally with 120 clicks for a smooth motion that feels nice. Arabic numerals are set at the even numbers with dots at the odd and a large inverted triangle at 12 o’clock. 

Materials

Seiko uses high-quality materials in the SSK001. The case and bracelet are made from surgical-grade stainless steel. The bezel is aluminum and polished to a nice finish. The same quality stainless steel is used for the hands. 

Dial

The dial is a black sunray burst beauty. I prefer neutral colors. They go with anything and provide a classic and timeless style. The sunray pattern gives the dial a bit of pop, especially in bright light. The Seiko name and logo are applied at the 12 o’clock position with the date function at three.

Pill-shaped indices sit at six and nine o’clock, with an inverted triangle at 12. Dots are set at the five-minute markers in between. All the indices are applied and filled with Lumibrite, such as the minute, hour, and GMT hands. You won’t have any trouble seeing the time at night.

The minute hand is a broad arrow, and the hour hand has the classic sword shape. The second hand is a needle, and the GMT hand is a large, red arrow that stands out nicely. The dial is covered by a Hardlex crystal. Would I have liked to see sapphire here? Absolutely. But we all know Seiko loves to cut corners, and the crystal is always one of its first priorities.

At three o’clock above the date complication sits a Cyclops magnifier. This is a feature that tends to divide watch enthusiasts. Some love it, some could live without it. Personally, I like the way it makes the date much easier for my aging eyes to read. A bonus is that it’s pill-shaped and adds a nice symmetry to the indices at six and nine.

Movement

The Caliber 4R34 automatic movement is reliable and durable. It has 24 jewels and operates at 21,6000 bph. For a watch at this price point, the accuracy of +45/-35 seconds per day is respectable, and the movement has a 41-hour power reserve. This is more than enough if you wear it every day. I keep mine on a watch winder, so it’s always ready to go. 

The Seiko SSK001 is a caller-type GMT, meaning you can’t set the hour hand separately. Pulling the crown out to the first position allows setting the GMT hand by turning clockwise. Counterclockwise changes the date. The second position sets the time by turning in either direction.

Strap

Holding the watch on your wrist is a stainless steel, five-link jubilee bracelet. The polished surfaces shine nicely. Seiko has improved on its earlier jubilee bracelet which tended to be jangly. This version feels more solid and wraps neatly around the wrist. The bracelet tapers to a trifold, two-button clasp that feels secure. Solid end links add to the look and feel.

Should You Buy A Seiko SSK001?

Is the Seiko SSK001 right for you? If you travel or do business with people in other time zones, you could benefit from a GMT. People with a sense of adventure will enjoy the dive-watch nature of this timepiece.

The neutral colorway is perfect if your style is classic and timeless. It’s a versatile watch that can be your GADA. If you are looking for a stylish, well-made, and reliable watch but don’t have the budget for a four, five, or (gasp) six-figure price tag, this may be the ideal choice. You get plenty of bang for your buck.

Seiko SSK001 Pricing & Availability

If you are ready to pull the trigger, the Seiko SSK001 is readily available at a Seiko store or from their website. You can also buy one at Seiko authorized dealers, like Exquisite Timepieces. You can always stop into our boutique in Naples, Florida, to try one on or purchase it online. There is also the option of purchasing one of these beauties new or preowned on the secondary market.

The MSRP of the Seiko SSK001 is just $475. If you shop around or have a good relationship with an AD, you might get one for a bit less and can also save by going preowned. Depending on the condition, you can pick a used one up for between $250 and $350. 

Seiko SSK001 Alternatives

If you like the Seiko SSK001 but would prefer different colors or strap options, there are several other models. They are all powered by the same movement and offer the reliability of the Seiko 5 Sports GMT watches with varying features and styles. With the exception of the Yuto Horigome model, they are priced the same as the SSK001.

Seiko 5 Sports GMT SSK003

The Seiko GMT SSK003  is identical to the SSK001 except for its color. It features a stunning blue sunray dial and a two-tone black and blue bezel. It is a bit bolder than its black-dialed cousin but retains a classy and subtle look. It’s a nice addition to any collection. 

Seiko 5 Sports GMT SSK005

Maybe you want a watch that really pops. The Seiko GMT SSK005 has a bright orange dial that will stand out. Along with its orange minute and hour hands and gray GMT hand, this timepiece makes a statement. The black and gray two-tone bezel offers a nice contrast to the dial. You get the same movement, bracelet, and reliability in a watch that suits a flashier sense of style.

Seiko 5 Sports GMT SSK021 Grey Two-Tone

For the same subtle, timeless style with just a touch of bling, check out the Seiko GMT SSK021. The classy gray dial and matching minute and hour hands blend well with the two-tone black and gray bezel. The outer edge of the bezel is a shiny gold color that matches the GMT hand. It adds a touch of boldness without being in your face. The movement and bracelet are the same as the SSK001. 

Seiko 5 Sports GMT SSK019 Black

Perhaps you love the bracelet and elegance of the SSK001 but want just a little bit of color. The Seiko GMT SSK019 may be the perfect watch for you. It has the same black sunray dial, black and gray bezel, and red GMT hand but with an added twist. The outer edge of the dial is two-tone red and blue. It makes the dial stand out but is not ostentatious. 

Seiko 5 Sports SSK027 Yuto Horigome Limited Edition

For exclusivity and a look that stands out in a completely different way, you may love the Seiko SSK027 Yuto Horigome Limited Edition. A tribute to the first-ever gold medalist in Olympic skateboarding, Seiko only made 2700 of these pieces, so you may have to track down a pre-owned watch. The brand-new models have an MSRP of $525, just slightly higher than the others in the collection.

The stainless steel case and bracelet are the same style and quality but coated in black. The black dial is surrounded by a black and purple two-tone bezel. It’s a unique look for the Seiko 5 GMT collection, and you will have a conversation starter that you won’t see on the wrists of many other people.

Conclusion

Diver GMT watches are among the most popular with watch enthusiasts. They do tend to be pricey and outside the range of many people’s budgets. Seiko has come to the rescue with the Seiko SSK001 and the other models in the Sports 5 GMT collection.

A stylish, reliable, and well-made GMT diver can be yours for less than half a grand. Imagine that. One final bit of advice. The Seiko Sports 5 GMT watches have a 100-meter water resistance. Go ahead and swim in them, but if you’re snorkeling around a reef or have a diving adventure, leave your Seiko on dry land.

Watches with complications tend to be among the most popular with collectors. Moon phases, power reserve indicators, days, dates, and tourbillons are useful as well as fun and stylish. Even though I have a calendar app on my smartphone, I need to see the date displayed on my watch.

Complications require more intricate movements and dials and are, thus, more expensive than standard three-hand models. For newbies to the world of watch collecting or veterans on a budget, it can be hard to find an affordable timepiece with the desired complication. This is especially true of GMT watches.

This is a complication that is extremely helpful to travelers or those who do business with people in other timezones. Sure, you can do the math, but it’s so much easier and way cooler to track more than one timezone on your watch.

GMT watches tend to be very expensive. A simple Google search will bear that out. However, the folks at Seiko have a collection of GMT watches that retail for less than $500. You read that right. You can own a beautiful Seiko 5 GMT at a price that won’t blow up your budget. Let’s take a closer look at these marvelous bargain-priced timepieces.

About The Seiko 5 GMT

The summer of 2022 saw the release of the Seiko 5 GMT collection. This event was not only huge for Seiko and its many fans; it knocked the world of horology on its butt. All of those budget-conscious watch lovers who couldn’t afford a GMT now finally had one to add to their collections.

Part of the Seiko 5 Sports Line, the SSK GMTs share many design features with their older cousins of the SKX Series. Available in a number of dial and bezel colors on bracelets or straps, these watches are clearly Seikos but have a unique charm of their own.

History of Seiko 5 Watches

The Seiko 5 collection has a long history. The first of the series, the Seiko 5 Sportsmatic 5, was released in 1963 and was a groundbreaking timepiece for the brand. The Sportmatic was the first automatic day-date for not only Seiko but also any Japanese brand.

The “5” in the model name represented five key attributes: the automatic movement, the day-date complication, 100-meter water resistance, the recessed crown at four o’clock, and the durable case and bracelet. The number was also used to name the Caliber 5 automatic movement. The watch was such a hit in the world of horology that Seiko earned a Good Design Award in early 1964.

Over the past six decades, the collection has evolved to include many types of sports watches. The SKX series of dive watches was released in 1996 and proved enormously popular. Unfortunately, Seiko discontinued it in 2019. The Prospex is still available and is an excellent diver, but that’s another story for another day.

The Seiko 5 collection continued to evolve to include casual and field watches, which are still available. This leads us to the glorious summer of 2022. Seiko entered the world of GMT watches with an affordable timepiece of this type that checks many of the boxes for GMT fans. In my opinion, it is the best in this class.

Seiko 5 GMT: In-Depth Review

The Seiko 5 GMT watches live up to the brand’s tradition of quality and aesthetics. With the number of colorways, case sizes, and strap options available in the line, there is something to please nearly every GMT lover out there.

Case Sizes & Materials

With the exception of the SSK027 Yuri Horigome Limited Edition and the SSK025, which have black-coated steel cases, all of the Seiko 5 GMTs feature stainless steel cases. These are durable and beautiful, with brushed surfaces on the top of the case and polished on the sides.

There are two case sizes available: 39.4mm and 42.5mm. This puts them dead center in the range that looks good on most wrist sizes. My average-sized 7.25” wrist is nicely covered by cases in this range. For people with smaller wrists, the 46mm lug-to-lug measurement makes the larger case wear more like a 40mm. Either size should suit you well.

The thickness of the case is 13.6mm, which is not bad for a GMT movement. The crystal is flat and gives the illusion of a slimmer watch. It’s a fairly hefty watch at 148g, but despite its solid feel, it doesn’t look chunky on the wrist.

Bezels

The bezels on the Seiko 5 GMT watches are of the 24-hour variety, as you would expect. The top of the bezel at the 24 marker has the large, upside triangle typical of GMT bezels with numerals at the even numbers and round indices at the odd. The bezel is two-colored to indicate day and night. The colors coordinate with the hue of the dial.

The bezel is unidirectional, making it easy to set. When you move it, you will notice a difference from the typical bezel. Rather than a 48-point click, the Seiko 5 GMT bezels turn with a friction feel. It can be a bit disconcerting if, like me, you enjoy the feel of a dive watch bezel. It functions well, however, and it can be set in half-hour increments to accommodate odd time zones such as Indian Standard Time (GMT +5:30).

A nice feature of these bezels is that the inserts are covered with a layer of Hardlex. This gives them the look of a ceramic bezel you would find on a much more expensive timepiece. You have to get pretty close to notice that it’s not ceramic.

With the 24-hour scale on the rehaut, the modders out there could fit an elapsed-time bezel from a Seiko diver to have a GMT dive watch. Be warned that this would be a desk diver. The crown is not a screw-down, and with the 100-meter water resistance, you don’t want to be playing Jacques Cousteau with this watch.

Dials

The dials are available in several colors and clearly designate the watches as Seiko with the brand’s well-known layout. The Seiko name and logo are applied at 12 o’clock, while at 6 o’clock, the word “automatic” is applied along with “GMT” in a color that contrasts the dial and matches the GMT hand.

The Seiko 5 GMT dials are designed to be easy to read. A large upside-down triangle indicates 12, with pill-shaped indices at six and nine and round indices at the five-minute marks in between. The three o’clock position is where the date window sits. For better legibility, it is covered with a cyclops lens in the Hardlex crystal.

This feature is somewhat divisive in the watch community. Many people love a cyclops, others not so much. In the case of Seiko 5 GMT, the cyclops does a nice job of magnifying the date. People who regularly travel across timezones will appreciate the feature. A secondary benefit is that the magnified date nicely matches the pills at six and nine. So, kids, if you’re like me and you prefer symmetry, the cyclops is for you.

The handset is classic Seiko with the large arrow minute hand, Roman sword hour hand, and needle second hand with a lollipop on the back end. The GMT hand is a generously sized arrow. On most models, it’s a bright red. On the SSK005 orange dial model, it is a high-contrast gray. The handset stands out against the dial, making it easy to read, whether you are on the go, or tracking time zones from your desk.

The dial and hands are covered with LumiBrite, typical of a Seiko timepiece. It provides a long-lasting brightness that allows you to read the dial in the darkest conditions.

Movement

The movement is the latest version of Seiko’s 4R line, the 4R34. It’s a reliable automatic movement running at 21,600 bph that features hand winding and hacking and has a 41-hour power reserve.

The Seiko 5 GMT is a caller-type watch. In other words, the hour hand can’t be set independently like in a traveler style. Pulling the crown out to the first position allows you to set the date by turning it counterclockwise. A clockwise turn sets the GMT hand. By pulling the crown out to the second position, you can set the time.

The Seiko 5 GMT watches have exhibition case backs covered with Hardlex. The finish on the 4R34 is nothing particularly special, but a true watch lover enjoys seeing the works of the timepiece. You can also show your horologically challenged friends how your watch winds itself.

Strap Options

Most of the Seiko 5 GMT models come with a stainless steel five-link jubilee bracelet. Seiko has improved it from its earlier jubilees, which tended to feel jangly. The current bracelet forms nicely around the wrist and has a more solid feel. This is helped by the solid end links.

The bracelet tapers down to a folding, two-button clasp with the Seiko name stamped on it. Overall, the jubilee pairs nicely with the case and bezel for a bold and classy look. The SSK027 Yuto Horigome Limited Edition comes with a jubilee bracelet in black-coated steel to match the case. The SSK025 is a field watch with a calfskin leather strap in black.

Most Popular Seiko 5 GMT Models

There are a number of Seiko 5 GMT models from which to choose. They all feature the same careful construction, solid materials, and reliability. You get to choose the one that best matches your aesthetic and, of course, your wrist. Here are the five most popular Seiko 5 GMT watches.

Seiko 5 Sports GMT SSK001

Perhaps the most popular of the collection, the Seiko 5 Sports GMT SSK001, is a great choice if you like a less bold and more classy watch. It has a 42.5mm case and a matte black dial with a very subtle texture to it. The sliver minute, hour, and second hands, along with the red GMT, set up a contrast that looks as good as it is easy to read.

The bezel is bicolored in black and gray. In lower light conditions, the gray half can look black, but the bezel coordinates nicely with the dial.

Seiko 5 Sports SSK023

Next, we have the Seiko 5 Sports SSK023. The case is the smaller 39.4mm size. With its black dial sporting numerals rather than indices and a silver stainless steel bezel, it has a sophisticated look for the fashion-conscious traveler.

Gray hour and minute hands, along with the red-arrow-tipped second hand and bold red GMT, make it a snap to read at a glance. Unlike most of the Seiko 5 GMT models, the crown sits at three o’clock rather than four, and there are no crown guards, which gives this timepiece a lean look.

Seiko 5 Sports GMT SSK005

If you like a watch that makes a bold statement and pops on the wrist, check out the Seiko 5 Sports GMT SSK005. The 42.5mm case with a bright orange dial is sure to make a statement, especially when paired with the black and gray bezel with orange numbers.

The hour and minute hands are lume-filled and outlined in a lighter orange, while the second hand is light orange at the top and dark gray at the bottom. The dark gray GMT hand is super easy to read against the dial. This is a playful GMT model for fun-loving collectors.

Seiko 5 Sports SSK027 Yuto Horigome Limited Edition

For collectors who enjoy a special timepiece, the Seiko Sports SSK027 Yuto Horigome Limited Edition fits the bill. Only 2700 of these beauties were made. This watch is a tribute to the first-ever Olympic gold medalist in skateboarding.

The 42.5mm case is black-coated stainless steel and looks chic with the black dial and bicolor blue and purple bezel. The silver minute and hour hands, silver and black second hand, and red GMT hand provide easy legibility as well as style. The matching black stainless steel jubilee bracelet pulls it all together.

Seiko 5 Sports GMT SSK003

If you want something a bit bolder than black but not quite as bright as orange, you may love the Seiko Sports GMT SSK003. It has a 42.5mm case with a blue sunburst dial set against a black and blue bezel. Silver minute and hour hands, a silver and black second hand, and a red GMT arrow contrast the dial for a great look and ease of reading. You’ll see this model on the wrists of many discerning watch lovers. Maybe it belongs on yours.

Should You Buy A Seiko 5 GMT?

Now that you’ve learned about the collection, is a Seiko 5 GMT right for you? First, is a GMT a type of watch you need and/or want? For frequent travelers, those who do business with folks around the world, or who have family or friends in different time zones, a GMT watch can be enormously helpful.

Serious collectors who want watches of each kind in their collection will consider a GMT a must-have. If you have a large income and plenty of disposable cash, you will probably seek out a GMT from a high-end luxury brand with a hefty price tag. If you’re on a tighter budget, a Seiko 5 GMT is an excellent option. It makes a great first GMT or even a first watch for a newbie collector.

Seiko 5 GMT Pricing & Availability

The Seiko 5 GMT is a popular watch, and you shouldn’t have trouble finding one. You can find them at Seiko’s online store or a Seiko authorized dealer, either brick-and-mortar or online. You can also purchase one from an online dealer on the secondary market. The Seiko 5 GMT is the most affordable watch of its kind out there.

With the exception of the SSK027, which you can pick for $525 (it’s a limited edition, so it costs a bit more) Seiko 5 GMTs sell for less than $500. These models range from $415-$475. If you search around for sales, there are some generous discounts out there. If you decide to go pre-owned, you can pick up a well-cared-for Seiko 5 GMT that looks great for between $300 and $350.

Conclusion

In the world of watches, GMTs are popular, useful, and often priced above what many people can afford. Every serious collector should have a GMT. Thanks to Seiko, you can own a beautiful and reliable GMT timepiece without taking out a second mortgage. In my humble opinion, the Seiko Sports 5 GMT watches are the best option for anyone looking for a low-cost GMT.

Homage to Innovation, Excellence, and Sports

The Seiko Speedtimer is an outrageously efficient and functional budget chronograph. The Japanese-made timepiece is easily the only true chronograph under $700 and a top contender for top watches within $1,500.

What makes the Speedtimer so valuable? Or is it just an exceptionally affordable Japanese watch with inferior features? Find out in this in-depth review of the Seiko Speedtimer collection.

The Seiko Prospex Speedtimer Collection

The Seiko Speedtimer line is a collection of chronographs with varying functions, prices, color schemes, and two movements. 

Its premium models are the history-rich Mechanical Chronograph for watch enthusiasts who detest quartz. This collection includes four models with different dial colors but the same movement. 

Meanwhile, the Seiko Speedtimer seven-watch Solar Chronograph lineup is for those who want a bang for their buck. 

• Speedtimer Mechanical Chronograph (1k pieces Limited Edition)
• Three Mechanical Chronograph models
• Seven Solar Chronograph models

Made for Excellence 

Every watch in the Speedtimer collection is the perfect blend of classic style and modern innovation. Each is carefully crafted to pay tribute to Seiko’s rich and continuing tradition of sports timing, with a new automatic chronograph movement to capture every detail. 

And the Solar chronographs, despite being budget pieces, also inherit iconic designs for a fraction of the cost of mechanical classics. 

Whether you’re looking for a statement piece or a complicated timepiece, you’ll find it on a budget in the Seiko Speedtimer collection. 

It’s a Seiko thing: the Speedmaster 7A38 also carried the world’s first analog display quartz chronograph movement in the 1980s. And you can get this vintage piece for under $500.

Functionality, versatility, and affordability make the Speedtimer an anomaly.

History of the Seiko Speedtimer Collection

The first Speedtimer models rolled out in the 1960s before, during, and after Seiko were official timekeepers of the 64′ Olympics. 

The official release of the Speedtimer in 1969 ushered in a landmark achievement for Seiko and the Japanese watchmaking industry. It was the first time the world saw an automatic movement chronograph – even the Swiss had yet to achieve this. 

Seiko subtly reincarnated the Speedtimer in its modern line of Prospex sports watches. 

The star of the collection is the limited edition model with a plain white dial and injection hands. This concept is inspired by the 1964 Seiko Stopwatch, built for sports timing. 

All the Mechanical and Solar Speedtimer watches are also a nod to the past, with each collection sharing the same movement and specs but different dial designs. 

Intriguing Dials 

All Speedtimer models resemble the iconic Rolex Daytona but are original in their lane. Besides, the subdials of Seiko’s Speedtimer and Speedmaster watches (also thought to have been a replica of Omega Speedmaster) are timeless racing watch designs. 

But don’t get the illusion that it’s a cheap replica or an homage watch. Stay tuned to find out the Speedtimer’s originality.

Mechanical Edition Dial

Seiko produces four Speedmaster mechanical edition models: 

• SRQ037J1 
• SRQ043J1 
• SRQ039J 
• SRQ035J1(Limited edition model). 

They have varying dial and subdial colors, hands, and finish variations that draw inspiration from their original models of the 60s. 

SRQ071

This charcoal-gray dialed mechanical watch design is inspired by the 1964 Crown Chronograph – Seiko and Japan’s first chronograph wristwatch. 

While not identical, the beveled hour markers and sharp sword-like hour hands mirror the original model. 

Small second hands curved slightly downward to rest on the tip of the subdial markers and parallel to the tachymeter. Although subtle, this improves accuracy and reading legibility for racers, so you should be fine with measuring your speed over a distance.

The main difference from the Prospex classics, as with other mechanical successors, is the inclusion of subdials, tachymeter, and push buttons.  

SRQ043J1

Navy blue is an homage to the 1969 Speedtimer, but better. The dial has vertical hairline finishing, which changes from navy to vivid blue at varying angles. This helps when you don’t want to turn your wrist to read the time. The SRQ043 white subdials and outer ring further enhance readability. 

SRQ039J1

If you asked, the SRQ039 is my favorite dial color from the collection because it looks like my favorite jean.

The SRQ039 has the same specifications as the angle-changing model 043, except for its blue and black dial. It’s an acknowledgment of Seiko’s time as the official timekeeper of the 1964 Olympic games in Tokyo.   

SRQ071

This lovely Prospex Speedtimer is a spin-off of Seiko’s 1964 1/5th Stopwatch. That’s how it has a striking scale-like aesthetic with a plain white dial, needle hands, and 10-second progressive Arabic numerals. 

Solar Energy Dials 

Image from Seiko

The Solar powered Speedtimers have the most exciting color lineup, and the SSC813 “Panda” is the signature model. It’s a black and white color with a white dial and black subdials that look like the face of Panda. 

The third subdial is a power reserve indicator. The solar editions also have a unique slanting date window at 4:20 that draws mixed feelings among fans. 

Moreover, the SSC Speedtimer models have fixed external bezels with varying colors, unlike the mechanical editions with inner ring tachymeters. See the difference: 

History-Rich Cases 

Stopwatch-Inspired SRQ

The SRQ Speedtimers (mechanical edition) use a round polished stainless steel case that’s a muse of the 1964 stopwatch. All the mechanical watches have a 42.5mm diameter case that’s 50mm from lug to lug.

That’s a fine men’s watch size, especially since the SSC is a tool watch. It can also fit perfectly on a lady’s wrists, but they may not fancy its weight or size, but the SSC will be more suitable. Finally, the cases sport two push buttons and a crown in the middle, like the 1964 Stopwatch.

Perfect-Sized Solar Chronograph 

Seiko uses an entirely different case design for its SSC solar chronographs and I love their portability. I’m grinning from ear to ear as I write this wearing my 44m Diesel Armbar, wishing I could snatch the more comfortable Seiko SSC813. 

The case is only 39mm across and 45mm from lug to lug, which is still an excellent fit for even small wrists. At this size, it’ll be a perfect chronograph gift for a woman who loves to wear men’s or instrument watches. The case is another example of how Seiko blends history with modern innovations.

In this case, the SSC case is a concept from the 1969 Speedtimer. However, its seemingly sophisticated look results from its tachymeter bezel synchronizing with the in-dial 60-second markers. But is an upgrade of the classics. 

This design is another testament to the Japanese brand’s efforts to blend heritage with modern innovations.

Bracelets 

Mechanical Edition

One thing Seiko boasts about its Speeditimer bracelets is their low center of gravity. It’s a result of the curved lugs and thick case. You’ll find the same feature in the solar edition. 

But a higher-quality bracelet-to-case finish makes the mechanical edition bracelets stand out from Solar Speedtimers. They have finely and evenly polished cases and bracelets compared to the Solar models. 

However, it uses the pin and lock system for removing links, which is considered clumsy and old-fashioned by watch enthusiasts.

Seiko SSC813 (Solar)

The Seiko Speedtimer SSC813 has the same case and bracelet dimensions as the solar series. But stands out because of its black and white “Panda” dial. 

The Solar Speedtimer has a stainless steel bracelet and is secured with a three-fold clasp with a push button mechanism. That makes it easy to wear, comfortable, and safe from accidentally falling off the wrist. 

However, the SSC813 has roughly polished links that don’t match the case. We also saw this same issue decades ago in the Seiko Speedmaster. 

Still, it’s not a terrible or noticeable issue, despite pointing it out to you. Only watch enthusiasts can tell the difference and may feel irked, so it doesn’t change the fact that it’s a durable, scratch-resistant bracelet. 

Curved Lug

Seiko curves the lugs down to give room for the push buttons. It creates an illusion that it’s taller than its actual 13mm height or the Speedmaster with a downward design.

Tachymeter Designs 

Remember, the Speedtimer is a racing watch collection and, as such, sports a tachymeter. If you’re unfamiliar with the term, it’s the inscription around the rim of watches used to measure distance traveled over time. 

The Speedtimers have two tachymeter designs. First, the Seiko Speedtimer SSC813, for instance, has a circumferential tachymeter on a fixed black bezel. All the Solar Chronographs have the same type but with different color schemes. 

Second, the SRQ mechanical series tachymeter is within the protective ring – a stationary, plain stainless steel bezel.

Uniform Movements

When it comes to the movement, there are two options. You can either splurge for the mechanical caliber or economize with the functional solar-powered (quartz) editions. The mechanical movements will shock you.

Top-Of-The-Line Caliber 8R46

The mechanical chronograph collection uses Seiko’s iconic Caliber 8R46. This movement is designed and hand-assembled in-house by Seiko’s finest engineers. It’s interesting because many watch lovers still think all Seiko watches are mass-produced and have inferior movements. 

Well, not the SRQ Speedtimer, that’s for sure. With a vertical clutch and column wheel movement mechanism for generational durability and accuracy. 

The vertical clutch slows down the wear and tear process while the column wheel controls the “start,” “stop,” and “zero” settings. The caliber 8R46 is ultimately Seiko’s most powerful automatic movement for mechanical watches.

Solar-Powered Caliber V192     

If you underrated the SSC series because they’re quartz, sit down for a rethink. But if you fancy quartz movements, you’ll get a great deal. 

The Caliber V192, as you know, is solar-powered and has an impressive six-month power reserve when fully charged. But that’s based on if you only use the chronograph feature for one hour daily.

What’s more, the V192-powered Seiko watches have an accuracy of +/-15 per month. Admittedly, that’s a better accuracy than most Japanese movements that offer an average +/- 25 accuracy per day but it is subpar at this price range.  

In addition, it offers a power reserve indicator at 6 o’clock and a controversial date window at 4:20. The date window can be problematic to glance at without “breaking your neck” to get the right angle. 

Seiko Speedtimer: Pricing and Value

Mechanical Edition

The Seiko Speedtimer Mechanical Edition watches cost around $3,000 to $3,300, with the limited edition piece priced on the upper end. 

For $3,000, you will find a few mechanical chronographs on Seiko’s craftmanship level. Well, not unless you opt for preowned watches, like the Omega Speedmaster or Longines Master chronograph. 

Also, it’s packed with vintage appeal that pays homage to one of the most iconic watch releases in the Japanese watchmaking industry. And it’s only an homage, not a replica, as some people would have loved. 

And it’s ahead of similarly priced competitors because of its premium movement with a column wheel and vertical clutch combination. Finally, the Seiko Prospex Speedtimer’s +25 to -15 seconds accuracy per day is decent, especially for a mechanical racing chronograph under $3000. But you’ll find higher precision watches for less. 

Seiko Speedtimer SSC813 Solar: King Of Value

The Speedtimer Solar (priced below $700) has rocked the watch industry since its release. Even when it’s not compared to quartz movements, this work of art remains a top competitor for chronographs under $1,500. 

The SSC813 (solar Speedtimer) guarantees a high value for your buck with its polished stainless steel finish and an enticing Panda dial. 

Its solar charge is also a nice touch of functionality. You never worry about winding your watch and don’t have to sunbathe it to charge it. It charges in cloudy or sunny weather and under fluorescent light. 

However, a few collectors think Seiko could’ve given a finer bracelet-to-case finish. And added a GMT instead of a power reserve subdial. But it couldn’t be any less good.

It’s no news that Seiko is among the world’s most prestigious and value-driven watch brands. Ask any watch lover, aficionado, collector, or even a diver to describe Seiko in two words, and your answer will certainly be a variant of the phrase; Terrific Value! 

From the Prospex line (made up of sport/tool watches) to the Presage line (made up of dress/retro timepieces), the brand’s catalog is massive and modestly priced. This is especially true of the Seiko SRP series, a reinterpretation of the brand’s 6309-series divers, nicknamed Turtle by Seiko’s fandom.

A collection marked by highly functional tool watches for the commoner that hogged the limelight with its cushion-cased design. Though a massive hit upon its release, the SRP77x did not sit well with many collectors as most found the large case size too substantial for their wrists leading to the release of the Mini Turtle a year later.

About the Seiko Mini Turtle

Towards the end of 2017, Seiko officially announced the release of three small Turtle variants. They were the SRPC35K1, SRPC39K1, and SRPC41K1, all of which are divers. Most people leave the count at four (including the SRPC37K1), but the SRPC35K1 and SRPC37K1 are essentially indistinguishable, save for the fitted straps.

The SRPC35K1 features a stainless steel bracelet, while the SRPC37K1 comes mounted on a two-piece silicone band. Originally intended for the dreaded Japanese Domestic Market, Seiko took a turn and made these watches available across the globe as well due to the high interest.

The nickname “Mini Turtle” was given to the trio by Seikodom. This was because of their oval case that resembled a turtle’s shell – a stark similitude to watches in the SRP series. The SRP series was a reinterpretation of Seiko’s third generation of professional divers (the venerable Seiko 6309) and featured mid-level divers.

Enthralled by the resurgence of the Seiko Cult Classic, collectors and enthusiasts made a run for the Turtle. However, the comparatively large case diameter didn’t sit well with many people, leading to the peculiar Mini Turtle/SRPC model release. 

The Mini Turtle, which lives in the Prospex (or Professional Specifications collection), is solidly built for use in the professional world. Being a dive watch, and a retro one at that, the Mini Turtles are great for regular people who loved the design of the regular Turtle models but balked at the size and longed for a scaled-down version. All variants are reliable watches best suited for casual or business-casual wear.

These stainless steel timepieces all run counter to their bulkier counterparts regarding size, dial design, and crown position at 3 o’clock. The case size is now 42.3mm (a 2mm drop from its predecessors), and the 4R36 automatic in-house caliber has now been replaced with the 4R35. In lieu of the day/date display at 3 o’clock is a date complication with a magnifying glass on the Hardlex crystal.

For their looks, the SRPC39K1 flaunts a matte blue dial and blue bezel. The SRPC35K1 (& SRPC37K1) has a black dial and bezel, while the SRPC41K1 (developed primarily for divers) is co-branded with PADI (Professional Association of Diving Instructors) and features a wavy black dial with Pepsi-style bezel and red minute hands. 

In summary, when compared to Its predecessor, the five most notable changes that can be observed are: smaller dimensions, relocation of the crown, elimination of the day complication, addition of the magnifying glass, and use of the 4R35 caliber movement.

Seiko Mini Turtle History & Origin

Since the release of Seiko’s (and Japan’s) first dive watch (the 62MAS-010) in July 1965, the brand has continued to introduce divers that topple the Swiss watch industry earning itself a top spot in the world of watchmaking. 

Seiko’s invasion of the world of divers has been innovative, and the SRP collection is one of such outstanding inventions. The line boasts a historic design that continues to charm collectors and enthusiasts alike with its warm retro vibes.

Coming as a reinterpretation of Seiko’s third generation of professional divers (the venerable 6309), the roots of the present-day Seiko Turtle stretch back to 1976 with the debut of the 6306 and 6309 models. The ref. 6306-7000/1 was released for the Japanese Domestic Market only, while the 6309-7040/9 was the worldwide version.

Modeled by Seiko’s master watch designer, Ikuo Tokunaga, the collection was a follow-up model to the ref. 6105, the very first cushion-shaped case watch from Seiko. 

However, unlike the ref. 6105, the 6306, and 6309 models were dubbed ‘Seiko Turtle’ because they were considerably more globular and symmetrical. The timepieces came with a smooth-edged case that protruded on both sides of its crown, giving them the appearance of a turtle’s shell when viewed from above.

With a depth rating of 150 meters, the 6306 and 6309 references offered extraordinary durability that could satisfy any recreational diver’s demands and be used for decades without worrying about servicing. With a diameter of 45mm, the watch might have been overly big then, but the cushioned case and crown at 4 o’clock made it surprisingly comfortable on the wrist.

Even though the JDM models were more alluring (and expensive) since they featured more jewels, hacking movement, and an English/Kanji day-date wheel, the ref. 6309 largely ruled Seiko’s entry-level diver’s segment until 1988, when the line was discontinued.

To the ecstasy of vintage Seiko connoisseurs, the brand re-launched the SRP series in the Prospex line in 2016 after over 20 years of dormancy. The new Turtle models were nearly identical to the 6309 models and featured the historic trait of the Turtle line; a cushion-shaped oval case and a crown at the 4 o’clock position, but now had an upgraded water resistance rating of 200 meters.

With a case size of 44.3 mm (the “King Turtle” variants measure 45 mm), the new Turtles were a bit cumbersome for people with smaller wrists, leading to a downscale version/three smaller variants measuring 42.3 mm in diameter. The new variants were instantly dubbed Mini Turtle since they were smaller, more compact, sleek, and elegant, giving everyone a chance to strap on a piece of history.

Seiko Mini Turtle Review

Case

Like its predecessors, the Mini Turtle sports a cushion-shaped, oval case. The 316L stainless steel case measures 42.3mm in diameter and has beautifully curved, polished sides with a very high mirror finish. 

For the height, it is 13mm thick, with nice 22mm lugs that are detached from the flange revealing the attachment between the bezel and mid-case where the strap passes through. 

Unlike its predecessors, all the versions of the Mini Turtle have unguarded crowns at 3 o’clock (rather than 4), which screw down firmly for excellent water resistance. Even though some dive watch enthusiasts consider the position of the crown a downside, it works great. 

The top of the case features a consistent circular brushing giving it a sunburst sheen, while the case back has the standard Katsushika Great Wave by Hokusai etched in the middle. In addition, you’ll find the Prospex logo, Diver’s Watch 200m, Stainless Steel, and 4R35 inscribed around the edges of the case back.

Dial

The dial is everything you’d expect from Seiko; clean, ultra-legible, highly contrasting with precise execution of all the details. 

The Turtle’s emblematic look, which has demonstrated its effectiveness for decades, can be recognized instantly. Even though the layout of the dial is relatively unchanged from earlier iterations of the Mini Turtle, the polished steel applied indices for the Mini-turtle are exclusive only to its variants. 

Rather than the regular printed or applied circular indices with some form of a triangle at the 12 o’clock position, the Mini Turtles’ are somewhat rectangular with rounded ends and syringe extension markers at all the cardinal points (6,9, and 12 positions).

Like most Seiko divers, the dials feature a charmingly minimalistic and elegant look with well-executed lettering. SEIKO can be seen at the 12 o’clock position, and right down at 6 o’clock is the Prospex “X” logo, followed by the words AUTOMATIC and DIVER’S 200m beneath the logo.

Again the words ‘Made in Japan’ can be seen across the edge of the dial, flaunting the noble quality and superiority of the timepiece. The brilliantly new textured dials are all about legibility and feature an insane amount of Seiko’s famed proprietary LumiBrite lume, applied generously on the hands and indices.

Unlike its predecessor, the day/date display at three has been given up for a simple date display with circular cyclops for ease of reading.

Size and Proportions

The size and proportions of the Mini Turtles are where a major change from its predecessor has occurred. The core of the case design has not changed, but it has gained a more defined shape, with curves and flow, getting rid of the bulky feel the previous models had.

The diameter is now 42.3mm though it used to be 44mm to 45mm in the past generations; thus, a 2mm decrease compared to previous Turtles. The thickness has remained at the same level (13 mm), and the lug-to-lug measurement is at 43mm – which is thinner than its predecessor’s and very compact for its size, making the Mini Turtle suitable for most wrists.

It weighs approximately 154 grams, roughly 40 grams less than the weight of the Turtle SRP77x on a bracelet, so it can be worn for several hours without a bulky feel.

Movement

The Mini Turtle is equipped with the 4R35 caliber movement, a remarkable upgrade from the popular 7S26 movement, which did not offer the expedient hacking and hand-winding function. Beating at 21,600 vibrations per hour, the Seiko’s in-house caliber 4R35 automatic movement contains 23 jewels and features a power reserve of approximately 40 hours.

The elevated quality of the Mini Turtle transcends beyond aesthetics to mechanical properties, as the 4R35 boasts noteworthy robustness from Seiko’s Diashock anti-shock system. The proprietary Diashock technique entails a spring-loaded mounting system that supports the balance wheel and absorbs impact, keeping the timepiece highly accurate and reliable for decades. Overall the mid-tier movement is solid, has an accuracy rating of -35/+45 seconds per day, and should supply years of service-free usage.

Crystal/Bezel

You guessed it right! Protecting the dial is Seiko’s proprietary impact-resistant Hardlex crystal. The flat Hardlex crystal comes with a very thin magnifier (cyclops) over the date display at 3 o’clock. Despite being relatively affordable, the watch glass offers impressive resistance to scratches and cracks compared to mineral crystals.

No kidding, it will survive great impact – even smashing against a rock. Moving forward, the aluminum bezel insert of the Mini Turtle is spectacular. It is fully indexed, making it suitable underwater and for timing all sorts of activities. 

The bezel is unidirectional and rotates at 120 clicks per round (anti-clockwise). It has thickset white numbering in intervals of 10 with white minute marks around, helping the wearer track time. A recessed luminous pip can be seen above the 12 o’clock position as a reversed triangle. Coloring for the bezel differs depending on the variant, but all are very well expressed and finished by Seiko.

Strap Options

The Mini Turtle is a dive watch, and depending on the model, you can choose any great strap that offers you a comfortable fit. Purists will tell you no other strap is ideal for a diver’s watch except metal, rubber, or nylon, but this is no rule.

The 42.3mm width of the case and a short lug-to-lug distance is precisely calculated to keep the Mini Turtle firmly proportioned on the wrist, so any curved end watch strap that can provide an ergonomically comfortable fit is ideal.

The use of color on the Mini Turtle is also well-balanced, which means you can choose any simple strap that is great for casual/ business casual environments depending on the model.

Bracelets, suede, perlon, NATO, and rubber straps are great options, but straps that are resistant to dust, odors, UV radiations, and sweat are highly recommended.

Top 3 Alternatives To The Seiko Mini Turtle

Seiko Prospex King Turtle SRPE03K1 

Right up the top of the list is none other than the King Turtle SRPE03K1 with a similar bold design to the Mini Turtle. The cushion-shaped King Turtle is a particular gem in the SRP series, adored by many diving enthusiasts.

It has everything we loved in the original Turtle; 200 meters of water resistance, a screw-down crown, a day-date complication, a robust in-house movement, and a fully marked bezel. But it goes further to add almost everything the original Turtle left to be desired; a Sapphire crystal, hacking and hand-winding movement, and a bezel action that feels smoother and sturdier.

The watch is equipped with the in-house caliber 4R36 with 24 jewels and provides approximately 41 hours of power reserve. Though slightly bigger than the Mini Turtle at 45mm in diameter (hence the nickname), the King Turtle does not feel oversized on the wrist thanks to its relatively short lugs of approximately 22mm.

Expect to spend around 600 USD for a new piece, as seen on Amazon. It’s more expensive than the Mini Turtle, yes, but the Sapphire crystal upgrade is well worth the premium.

Hamilton Khaki Navy Scuba Auto H82335131

Popular for unique aviation-inspired watches, Hamilton stands out for constantly consolidating Swiss watchmaking traditions with classic American styles. Measuring 40mm in diameter, the Navy Scuba Auto from Hamilton is a perfect alternative to the Mini Turtle. From the case to the bracelet, bezel, and dial, this model is distinct and well-designed. 

Just like the Mini Turtle, it features a clean dial with large hands — the minute hands even have an arrow shape at its tips that is distinguishable thanks to its striking red color. The dial is protected by Sapphire crystal and is water resistant up to 100m. It is equipped with Hamilton’s H-10 caliber, a three-hand movement with a power reserve of up to 80 hours.

You can get it here for 650 USD or around 400 USD for the quartz variation (ref: H82201131).

Dan Henry 1970

Notable in the vast watch world for creating vintage-inspired timepieces is Dan Henry, a watch brand that was created by an avid watch collector. If you absolutely want to replace the Mini Turtle with a great affordable alternative, the Dan Henry 1970 is the perfect compromise because of its vintage and sporty look. 

The case measures 40mm with a lug-to-lug width of 22mm. The matte dial is all about legibility with a 60-min inner rotating bezel and a welcome addition of applied hours indices.

It is equipped with the caliber NH35 from Seiko, a reliable but affordable movement that offers a decent power reserve of approximately 41 hours. It is water resistant to a depth of 200 meters and goes for 290 USD on Dan Henry’s official website.

Conclusion

Once again, Seiko adheres to its proven recipe: maintaining the great points and never breaking the codes. While there are great alternatives to the Mini Turtle out there, you’ll hardly find an entry-level timepiece that offers such profound consistency in its design and quality.

The watch has been at the end of the accessible divers, and there are tangible reasons for this. The overall execution is superb, with outstanding consistency in the build and form. The accuracy of the assembly, the superiority of the parts used in all areas, robustness of the movement, comfort, and compactness of the bracelet and clasp… 

There’s no denying that everything has been considered with much attention. As for the price, the Mini Turtles have been discontinued (so hold tight to yours if you got one), making them more expensive now. Expect to spend around 370 USD for a new piece on Amazon.
