Grand Seiko SLGW003 Review: The Pinnacle of the “White Birch”

It seems that every time I talk about Grand Seiko, I spend all my time raving about their elegance and innovation, praising them for their craftsmanship and attention to detail. They have managed to capture the essence of watchmaking and seem to personally inject whatever secrets they hold into each and every piece. The Grand Seiko SLGW003 is a striking testament to this philosophy. 

Part of the Evolution 9 collection, the SLGW003 is a relatively newer entry to the iconic family that houses so many recognizable names. It comes equipped with the Grand Seiko Caliber 9SA4, the first manual-winding 36,000 vph mechanical movement Grand Seiko has created in nearly 50 years. 

They incorporate the manual design to forge a deeper connection between the watch and the wearer, claiming that the ritual winding of a watch is one of life’s pleasures. In the 60s and 70s, Seiko produced numerous manually wound pieces, attempting to deliver higher precision to each design. 

This watch signifies their grand return to these more old-fashioned pieces, but not without improving upon the original design, displaying their drive to always increase their level of craftsmanship. 

Wrapped in a shroud of sophistication with the advanced technology of the modern age, the SLGW003 delivers on all fronts, ensuring that the wearer looks their best while being easy to read, wind, and wear. 

History

Released in 2021, the Grand Seiko SLGW003 immediately made a name for itself among the Evolution 9 collection. Drawing inspiration from Japan’s rich cultural heritage and birch forests that reside near the Grand Seiko headquarters, this watch embodies the striking beauty of Japanese nature, as well as the detail-oriented precision of Japanese society. 

Taking inspiration from the old manually wound 10-beat designs from the ’60s and ’70s, this watch could be considered both a throwback and a step forward. It incorporates old themes and new functions that excel in practicality and leave the wearer in awe of its mechanical prowess.

Case 

Titanium cases are among my favorite materials. Lightweight, sleek, luminescent, and subtle, they satisfy every desire and check every box when it comes to the beauty of your pieces’ case. Grand Seiko’s hard titanium comes with all the benefits of regular titanium, incorporating a beautiful Zaratsu polishing that only adds to the beauty. 

The diameter is 38.6mm, the lug-to-lug is 45.0mm, and the thickness is 9.95mm, measuring very thin all across the board. The contorted lugs help with wearability and give it an even slimmer aesthetic, which will appeal to many of you who prefer the sleeker designs. 

The Zaratsu finish accompanies both the inner crease and the bezel, while matte finishing accompanies the sides of the case. The sapphire crystal protects the dial while rising slightly above the rest of the case due to it being slightly domed. The casing has been made with a low center of gravity to ensure that it still sits securely on your wrist, no matter how light it is. 

The crown protrudes from the three positions, proudly embroidered with the GS logo. And when you turn the case around, you are met with the welcomed surprise of an open case-back so that you can view the mechanical integrity of the piece.

The case exemplifies an understated charm, reinforcing the significance of the watch’s other features while also catching the wearer’s eye with its beautiful titanium elegance. Successfully designed casing exists for two significant reasons: First, it has to look aesthetically pleasing by itself, but the most important reason is that it has to elevate everything around it. 

The beauty of the watch starts with the casing. It serves as a foundation around which the other features center themselves. Grand Seiko has delivered an effective foundation and, by using its staggering beauty, has crafted one of its most impressive pieces yet.

Dial

The dial is highly textured with a unique white birch tree bark style that is unique to this series. While at first, it may seem familiar, as the SLGH005 appears very similar to the Grand Seiko SLGW003, the white birch pattern has far more textures on the SLGW003, and the pattern is moving horizontally on the SLGW003 as opposed to vertically on the SLGH005. 

The bezel seems to focus on giving the watch a dressier appeal as the textures breathe an unprecedented style of luxury and pristine craftsmanship that is far more detailed than anything we’ve seen before. 

Other than the Grand Seiko logo and the text at 6 o’clock, there are no complications in the dial, ensuring that the wearer is satisfied with the symmetry and cleanliness that the dial seeks to emulate.  

The indices are broad and easy to read, taking the common shape of the Series 9 style. They are polished to perfection and give a beautiful complementary look to the backdrop of the dial, standing out from the birch-wood background in an elevated manner. 

The same goes for the hands. When everything on the dial is the same color, it tends to blend together. This piece brings out a stark boldness to each feature while keeping them all the same shade. Nothing seems out of place or distracting. The hands are elegant and slender, which goes well with the size of the piece itself. 

This is one of the cleanest dials we’ve seen from Grand Seiko, and it is among my personal favorites. The birch-wood texture’s underlying simplicity and the titanium’s elegance seem to be a combination sent from heaven to give us one of the most extraordinary designs. The removal of a date window does many favors for the integrity of the dial as well. 

Part of the beauty comes from the symmetry, and I feel like if you tried to fit anything else in the dial, then it would undermine the original vision. Skilled watchmakers know when to restrain themselves. 

Sometimes, less is more, and Grand Seiko seemed to go into this project with that idea in mind. I would say it worked very well for them, and I’m eager to see if they replicate this design choice in any future pieces. 

Movement

Engineered with the sole purpose of providing the ultimate hand-winding experience, the Caliber 9SA4 comes with a pleasing winding sound, demonstrating its craftsmanship and quality. It has a high frequency of 10 vibrations per second, which accounts for the 80 hours of power reserve. 

This is the first hand-wound, high-beat movement that Grand Seiko has produced in more than 50 years, and given how they treat the rest of their works, you can be sure that the 9SA4 has been finely tuned and perfected with the same attention to detail as all of their other pieces. 

Grand Seiko has rearranged the gear train and redesigned many parts, ensuring that the Caliber 9SA4 achieves a power reserve of 80 hours with 15 percent fewer crown rotations than the Caliber 9SA5. 

This plays a role in the slimness of the watch and explains how a manual watch can achieve these kinds of numbers. It is also extremely accurate, with a mean daily rate of +5 to -3 seconds per day and a normal usage accuracy of +8 to -1 seconds per day. 

On a day-to-day basis, this watch is going to provide you with everything you need and more. An 80-hour power reserve from a manual is quite the treat, and the luxury it emits while you wind it is a nice little bonus feature that wearers can enjoy. The beauty of the 9SA4 cannot be understated. 

With 47 jewels, it shines from the open case back and adds to the aesthetic of the entire piece. Watching it subtly rotate and shift presents another theme to the design. Grand Grand Seiko claims that manual watches help us feel more attached to our pieces and help us appreciate the passing of time as we observe the mechanical power. 

The open case back was a necessary choice to ensure that connection is felt while it is being worn. As time passes, the wearer can appreciate that this watch will never change and that with every turn of the crown, you can be sure that the integrity of the watch never falters.

Straps

The strap is black and made out of crocodile leather with matched stitching and a three-fold clasp. It feels very premium and supple, almost as if it’s already been worn in. This could be a pro or a con, depending on whether or not you appreciate a more natural feel on your wrist or you want to wear the strap yourself. 

The light reflects very solemnly off the black leather, giving it a glare that can either complement the whiteness of the dial or contrast it due to its dark natural colors. Both of these looks are very aesthetically pleasing in their own right, but I prefer the subtle compliments that the lighter shade gives. One mark of a good strap is whether or not it can transform when the light hits it just right. 

It can completely change the piece’s overall look in both positive and negative ways. This is undoubtedly a positive, as the birch texture of the dial fits comfortably in between the two glowing sides of the leathery straps. 

You most likely won’t want to change this beautiful strap, but the drilled lugs and 20mm lug width will make the process seamless. This piece benefits greatly from a leather strap because the casing and the dial reflect a sleeker, more reserved look. The watch itself is very thin, and I feel a steel bracelet would appear disproportionate compared to the rest of the watch. 

The crocodile leather is one material that has grown on me. I was hesitant about complimenting it when I first saw it, but this piece has single-handedly made me appreciate what can be done with the simple material. The texture is beautiful, comfortable, easy to swap, and frankly doesn’t miss. 

On-Wrist Experience

The dimensions make the watch very suitable for a wide variety of wrists, extending from as low as 6 inches to as high as about 7.5 inches or more. You won’t run into many issues fitting the watch. 

Thanks to the titanium, it feels very smooth and lightweight compared to a stainless steel watch, weighing just enough to remind you that it’s still on your wrist while not being overly heavy to the point of discomfort. Sleekly polished and finished to perfection, the titanium shines like glass, while the soft curved lugs ensure a snug fit.

The minimalist dial contributes to the overall sense of refinement, and the leather strap has the unique feel of molding to your wrist over time, almost as if it was made specifically for the individual wearer. The small nature makes it easy to slide under cuffs, which may be an advantage for those of you who prefer that style. 

Although I found that wearing this piece on the outside of your cuffs does tremendous work on the aesthetic Plus, I don’t know why you would want to hide this piece. It should be something you feel proud to show off. 

Overall, I’ve found this is a dressier watch—not to argue against the idea of wearing it in another environment. The heftier price alone alludes to its high-end nature, and dressing accordingly would elevate the luxurious nature of the piece even higher. 

But—and don’t get me confused—you would be fine wearing it in any environment because you’re not sacrificing comfort for something more pristine. In this piece, comfort and beauty walk side by side, so the wearer shouldn’t be concerned about when or when not to wear it.
