Quick TakeThe SLGW002 is, simply, a testament to the harmony of form and function. Dressed in its warm rose gold case, the watch feels substantial but not overbearing, a testament to the Evolution 9 Collection's dedication to wearability. The case lines are crisp, almost architectural, with those slimmed-down lugs presenting a silhouette that's both familiar to the 44GS and forward-looking. The dial's organic birch bark texture dances in the light, playing off the warmth of the rose gold hands and markers. But this is no mere showpiece. That high-beat movement, a technical marvel in itself, delivers exceptional accuracy. The deliberate choice of manual winding isn't just a nod to tradition—it's an invitation to interact with this timepiece on a more intimate level. The SLGW002 is the embodiment of Grand Seiko's core ethos. It's a watch that invites you to connect with the very essence of timekeeping, a refined yet robust companion built to the highest standards. It feels like horological poetry on the wrist.

DescriptionThe Grand Seiko reference SLGW002 is a remarkable example of precision engineering and elegant design, belonging to the highly regarded Evolution 9 Collection. Housed within a 38.6mm diameter, 9.95mm thick 18K rose gold case, this timepiece exudes sophistication. The case has a see-through case back secured with six screws, providing a glimpse into the intricate workings of the movement. Its box-shaped sapphire crystal features an anti-reflective coating on its inner surface, ensuring optimal readability. The case is constructed with a lowered center of gravity to augment comfort and stability on the wrist. Notably, the case lugs have been meticulously redesigned to be narrower and shorter, presenting a refined aesthetic while maintaining the signature Evolution 9 style. Its total weight comes in at 102 grams, owing to the precious metal case and substantial movement within. The watch is splash resistant and features magnetic resistance of 4,800 A/m. Other details are the "Limited Edition" marking on the case back, as well as a serial number engraved there, and a power reserve indicator.

At the heart of this limited edition is the manual-winding Caliber 9SA4, a 36,000 vibrations per hour movement that marks a significant milestone for Grand Seiko. This is their first hand-wound, high-beat caliber in approximately 50 years, achieving an 80-hour power reserve. The movement is notable for its efficiency, requiring 15 percent fewer crown rotations compared to the Caliber 9SA5 to achieve the same power reserve. The dial is adorned with a unique pattern reminiscent of birch bark, complemented by solid gold hour markers, as indicated by the SD (Special Dial) mark at the 6 o'clock position. The watch has a mean daily rate of +5 to -3 seconds per day under controlled testing, while normal usage accuracy is rated at +8 to -1 seconds per day. The timepiece is paired with a 20mm wide crocodile leather strap, fastened by a three-fold clasp with a push-button release. The lug-to-lug distance is 45.4mm. The case back is thoughtfully engraved with "LIMITED EDITION" alongside the individual serial number, emphasizing its exclusivity.
