Quick TakeThe SLGW003, affectionately nicknamed "the birch," is a different breed of dress watch. Its titanium case makes it feel feather-light on the wrist, and that hand-wound movement--a high-beat beauty--is a rare treat in today's world of automatic everything. Winding this watch is a ritual; a tactile pleasure that connects you to the flow of time in a uniquely satisfying way. You can practically hear the gears meshing, working in concert. The SLGW003's accuracy is also astonishing, keeping near-perfect time, day in and day out. It is a watch for those who appreciate the art of horology in its purest form. Grand Seiko has taken their classic design and subtly tweaked it, making the SLGW003 feel both familiar and fresh. The slim profile slips discreetly under a cuff, making the watch a statement of refined taste rather than ostentatious wealth. This watch is an ode to the subtle, the precise, and the enduringly elegant. This isn't just a watch; it's a statement of mindful appreciation for the art of timekeeping.

DescriptionThe SLGW003 is a significant addition to Grand Seiko's Evolution 9 Collection, representing a modern take on the brand's traditional dress watch aesthetic. The most notable feature is the manually wound Caliber 9SA4 movement, marking the first hand-wound 36,000 vph mechanical movement produced by Grand Seiko in around half a century. This high-beat movement delivers an impressive 80-hour power reserve, achieved through a refined gear train arrangement and redesigned parts. This results in 15% fewer crown rotations needed to fully wind the watch compared to the automatic Caliber 9SA5. The movement's svelte profile contributes to the watch's overall thinness of 9.95mm and diameter of 38.6mm. Functionally, it maintains a mean daily rate accuracy of +5 to -3 seconds, with normal usage accuracy rated at +8 to -1 seconds per day, measured across 12 days in six positions before assembly. The SLGW003 movement possesses a magnetic resistance of 4,800 A/m and offers a power reserve indicator function.

Aesthetically, the SLGW003 is fashioned from Grand Seiko's Brilliant Hard Titanium, an alloy that surpasses traditional titanium in brightness and durability. This material grants the watch a lightweight feel, weighing only 60 grams, combined with enhanced corrosion and scratch resistance. The hardness of this titanium alloy is double that of standard stainless steel, increasing the piece's longevity. The case design adheres to the Evolution 9 Style, refining the original Grand Seiko Style from the 1967 44GS. The design tweaks include slimmed-down, elongated, grooved indexes, and narrower, multifaceted lugs with a smaller surface area. The watch's lowered center of gravity ensures excellent comfort and stability on the wrist. This titanium case has a see-through case back with four screws, allowing observation of the movement, and it is paired with a box-shaped sapphire crystal with an anti-reflective coating on the inner surface. A crocodile leather strap with a three-fold push-button clasp complements the watch.
