Grand Seiko SLGA019 Review

Have you ever wondered what the texture of a lake would look like on a watch dial? No, me neither. But of course, nature-loving Grand Seiko has done just that, reinterpreting the blue-colored ripples of Lake Suwa onto the dial of their sporty Evolution 9 model. The result? 

From online images, it should be a sporty chic watch with a dial that leaves you pretty mesmerized. But is the Grand Seiko Evolution 9 “Lake Suwa” SLGA019 as good in person? 

Thankfully, I got hands-on with the model this past week to see if its impressive list of specs is up to scratch. As most of you know, we hold Grand Seiko in high esteem. They are one of just a few brands that have truly mastered horological excellence, proudly focusing on precision, elegance, and functionality. 

Because of this, however, we find ourselves with high standards when it comes to reviewing their watches. So is the Grand Seiko SLGA019 a masterpiece, or is it simply a novelty that fulfills the Japanese watchmaker’s obsession with nature? Let’s find out, shall we.

The Grand Seiko Evolution 9 Collection

Before we get into the nitty gritty details of the Grand Seiko Evolution 9 “Lake Suwa” SLGA019, we first need to take a stroll down memory lane and consider where this model came from. Back in 1960, Seiko decided to up their game and create a more luxury-focused range of watches. Enter Grand Seiko, a collection of timepieces with premium finishing, materials and movements. 

Fast forward to 2017 and CEO Shinji Hattori made the announcement that Grand Seiko would become a standalone brand, separate from the Seiko Watch Company. With the Evolution 9 collection, which was launched three years later, Grand Seiko outlined a set of nine design standards that every model must hit. 

These included elements like a flat dial, double wide index at 12 o’clock, multi-faceted hour and minute hands, and a bracelet with at least half the width of the case with the right thickness and heft. 

You might be thinking this sounds like all Grand Seiko watches. And in some ways, it is, but the Evolution 9 hits more differently than you might anticipate. In fact, some of the changes to the design are almost invisible to the naked eye. For example, the way the ergonomic case has a lower center of gravity on the wrist isn’t something you can see, but it’s something you feel once it’s strapped on. 

But does this apply to the Grand Seiko Evolution 9 “Lake Suwa” SLGA019? For starters, the Japanese watchmaker has forgone the classic flat dial for one inspired by the soft blue ripples of its namesake. 

The luxury watch company has habitually drawn inspiration from aspects of nature surrounding their factory, and this novelty is no different. This time, they look to Lake Suwa, a freshwater lake in the Nagano Prefecture of Japan, known for its natural beauty and hot springs. 

This isn’t the first watch from Grand Seiko to form a “Lake Suwa ” series. In truth, this is the third in a line-up of three. The first was reference SLGA007, launched as part of the brand’s 140th anniversary celebration. 

The second arrived shortly after, reference SBGY007, which utilized a slightly different, but equally exquisite “Omiwatari ” dial pattern and marked the first non-limited edition Lake Suwa watch. Then there was SLGA019, launching later in 2023 and becoming the lightest of them all.

A Lightweight Titanium Case

Arguably, the biggest difference between the Grand Seiko Evolution 9 “Lake Suwa” SLGA019 watch and the two launched before it is the case material. This time, the 40mm wide and 11.8mm tall case is machined from titanium, a material 30-35% lighter than stainless steel. 

This makes the SLGA019 incredibly wearable and comfortable, especially as an everyday dress watch. The metal also has a slightly warmer hue and softer appearance, plus it benefits from extra corrosion resistance.

This isn’t just any plain old titanium, either. It’s Grand Seiko’s patented high-intensity titanium, which offers a higher level of scratch resistance and durability than standard titanium. 

As I typically do with most titanium watches, I had to weigh it for myself, and according to my scales, reference SLGA019 weighs in at just under 112 grams. It’s a really nice weight for a dress watch; it’s not so light that it feels invisible, but it has a nice lightness that makes it effortless to wear when simply going about your business. 

As you’d expect from Grand Seiko, the finishing of the Evolution 9 “Lake Suwa” SLGA019 watch is exceptional. The angular case presents the Evolution 9’s small, sloping lugs with a brushed finish to match the vertically brushed fixed bezel and bracelet links. 

In contrast, the bezel and case sides are finished using Grand Seiko’s famous Zaratsu polishing, a technique that involves using a spinning tin plate coated with diamond paste to create a flawless, distortion-free mirror finish. 

The Grand Seiko SLGA019 sits on the wrist with a lug-to-lug width of 47.9mm and boasts dual-curved sapphire crystal glass on top, a screwed exhibition case back – also utilizing sapphire crystal — and a simple knurled crown at 3 o’clock. The crown offers screw-down capability for a reasonable 100-meter water-resistant rating and is topped by the “GS” logo. 

Lake Suwa-Inspired Dial 

Due to its name, many will admire the Grand Seiko Evolution 9 “Lake Suwa” SLGA019 most for its dial. Grand Seiko described the dial of the original Lake Suwa SLGA007 model to be inspired by “the calm waters of Lake Suwa”. 

The second (SBGY007) replicated the look of the water when it froze during the winter. This time, Grand Seiko suggests the lighter hue evokes “the surface of Lake Suwa and its gentle waves in the early morning hours when a breeze stirs the long, shallow lake.” 

In my opinion, this is the best of the “Lake Suwa” dials so far. Why? Because the shade of blue seems to change color depending on your surroundings. It stands out in a bold royal blue in direct sunlight, and yet, in the shade, it becomes an almost discreet shade of black. The supple ripple texture also gives the watch a certain sparkle; both the color and texture are highly responsive to light, reflecting it with every twist and turn. 

The hands and indices are also perfectly finished in the Evolution 9 style. Each hour marker is multifaceted, and the 12 o’clock marker has a double multifaceted shape. Despite not having a touch of lume anywhere on the dial, the display of the Grand Seiko SLGA019 is brilliantly legible. 

The dauphine-style hands are also broad and easy to read, offering classic hours, minutes, and seconds complication. The hour hand has a unique shape, with the end sliced off and a facet running down the center.

All the silvered hardware, including the boxed-in date at 3 o’clock, is brightly polished. My only complaint about the Grand Seiko SLGA019’s dial involves the date window. I can’t help but think, with a dial as beautiful as this, the date should have been neglected. 

And if a date must be insisted on, they should at least swap the white disc to one of navy for a more seamless, subtle finish. The dial is finished with the Grand Seiko logo added in relief at 12 o’clock and lettering denoting information about the movement at 6 o’clock. 

The Spring Drive Movement

Like the previous three Grand Seiko “Lake Suwa” watches, SLGA019 is powered by the Japanese brand’s in-house 9RA2 Spring Drive movement. This caliber cleverly combines the precision of a quartz movement with the smooth sweeping motion of a mechanical watch. This alone makes the SLGA019 a valuable timepiece, and when combined with the lightweight case and textured dial, there’s very little to berate. 

The quartz-mechanical hybrid is ingeniously engineered to maintain a remarkable accuracy of ±0.5 seconds per day or ±10 seconds per month. This exceptional accuracy is achieved through a combination of a quartz oscillator for timing stability, a mechanical gear train for power transmission, and an electromagnetic brake to regulate the speed of the glide wheel. 

The result is a movement that not only keeps impeccable time but also provides a unique tactile experience with its smooth, silent glide of the seconds hand. 

There’s plenty of pleasant finishing seen through the case back. I particularly like the frosted plates and bridges that are inspired by the frost that winter brings to the trees surrounding Grand Seiko’s manufacturing facility. 

As always, there’s blued screwed, beveled edges, 38 jewels, and an off-set magic lever to keep the movement, and consequently, the case, nice and thin. Rather than being placed on the front of the dial like most of Grand Seiko’s Spring Drive watches, the power reserve is positioned on the back of the movement, so when the watch is off your wrist, you can see what’s remaining out of its 120-hour reserve.

Titanium Bracelet

Like the case, the bracelet is made using Grand Seiko’s high-intensity titanium. It boasts a three-link construction with a completely matte finish thanks to the vertically brushed decoration. It tapers from a 22mm lug width where it meets the case down to a 21mm width where the buckle appears. The buckle is embossed with the GS logo on top and has folding functionality with push button release. 

One of the few weak points of the Grand Seiko Evolution 9 “Lake Suwa” SLGA019 is that the bracelet lacks any sort of micro-adjustment. This hampers its ability to be used as a daily wearer since anyone familiar with wearing metal bracelet watches will know your wrist can swell and contract as the day goes on and temperatures vary. 

It would have been a nice addition for Grand Seiko to include a micro-adjustment system on this bracelet; I know it’s a feature many GS enthusiasts have been hoping for in the Evolution 9 series. 

It also comes with push pins for sizing instead of screws, which is a little crazy for a watch of this caliber. I’ve said it once, but I’ll say it again: Grand Seiko does everything right until it comes to their metal bracelets.

The bracelet does arrive with drilled lugs, though, so you can easily swap around the strap to something more suitable if you want. The 22mm lug width means you’ll have an endless supply of strap options to choose from. If it were me, I’d invest in a better-styled titanium bracelet or a nice chocolate brown alligator leather band.

On-Wrist Experience

With a watch like the Grand Seiko Evolution 9 “Lake Suwa” SLGA019, wearability is essential. First impressions confirmed that this was a watch I could effortlessly wear all day, every day. Its titanium construction is incredibly lightweight, and its dimensions make it effortlessly wearable for most wrist types. 

The lug-to-lug is a little larger than I’d like, but the slender profile, sleek curves, and low center of gravity make up for this. I’d suggest the SLGA019 would be best suited to those with six and a half inch wrists and above – but even myself, with a five-and-a-half-inch wrist enjoyed the statement this watch made. 

While its case makes it a daily beater, the dial of the Grand Seiko Evolution 9 “Lake Suwa” SLGA019 makes it one of the finest dress watches in the collection. The detailing and shade of blue are divine, and as always, the finishing on the dial’s hardware makes it sparkle almost like a diamond in certain lights. Its 11.8mm height means it’s also ideal for slipping it under shirt cuffs – although if it were me, I’d keep this bad boy out in the open for everyone to see.

Price & Availability 

The Grand Seiko SLGA019 retails for $10,400 brand new and is available to order from your local authorized dealer, including Exquisite Timepieces. It can also be found on the second-hand market for around $6,500. It’s another non-limited edition design, but with how popular the “Lake Suwa” series has proven so far, I wouldn’t expect it to stay in stock for much longer.

Conclusion

Like any watch, the Grand Seiko Evolution 9 “Lake Suwa” SLGA019 has some room for improvement. Where the design is let down most is on the bracelet. I’m really hoping Grand Seiko up their bracelet game soon, as a watch like this deserves some micro-adjustment, and it especially needs to have screws rather than push pins. I’d also like to see the “Lake Suwa” series either dateless or at least with a color-matching date disc to match the textured display.

Other than that, the Grand Seiko SLGA019 is exceptional. The lightness of the titanium case, the levels of finishing on the case and bracelet, and the detail found on the detail are breathtaking. 

Then you have the in-house 9RA2 Spring Drive movement as the cherry on top. The weekday-proof 120-hour power reserve is extremely useful, and with a level of precision like this, you’ll never have an excuse for being late. I stand by my claim that this is the most handsome Grand Seiko “Lake Suwa” watch released so far.
