About Grand Seiko SLGW007
Grand Seiko Manual-winding Mechanical Hi-Beat 36000 80 Hours Evolution 9 Collection
A textured blue dial evokes a moonlit birch tree in this manual-winding, 10-beat mechanical timepiece
This 10-beat, manual-winding mechanical watch is based on the “Evolution 9 Style,” a unique design grammar that takes the fusion of Grand Seiko’s spirit with the aesthetic sensibilities of Japan to a higher level. Its textured, navy-colored dial evokes the bark of a white birch tree illuminated by the moon. Featuring a slender stainless steel case that is a mere 9.95mm thick, the creation has an appearance worthy of a Grand Seiko dress watch. The bezel is refined, with a narrow profile that complements the lugs, whose clean lines are echoed on the dial by the indexes. The manual-winding movement is the Caliber 9SA4, which features a high number of vibrations, 10 per second, to maintain a stable level of accuracy, as well as a generous power reserve of up to 80 hours.
Grand Seiko SLGW007 Features
Dial reminiscent of a white birch appearing faintly in the moonlight
Upon the Hiraniwa Plateau in Iwate Prefecture, the same prefecture that is the home of the Grand Seiko Studio Shizukuishi, where Grand Seiko’s mechanical watches are manufactured, an impressive forest of white birch trees extends across a large area of roughly 1,000 acres. The dress watch’s dial is fashioned in a finely detailed design that expresses the beauty of the irregular patterns of tree bark. The color of the dial is navy, with a slight hint of fading, evoking the bark of a white birch bathed in moonlight.
Strap that harmonizes the dial in both texture and color
The strap features a beautiful, soft texture with small bumps and a color that blends with the dial to reinforce the image of a white birch illuminated by the moon.
Caliber 9SA4
This movement is the result of Grand Seiko striving daily toward the goal of the ultimate in manual-winding timepieces. It features a high number of vibrations, 36,000 per hour, to maintain a stable level of accuracy, as well as a generous power reserve of up to 80 hours.

Grand Seiko SLGW007 History
Prior to 1960, to challenge the status of Swiss watches and change the perception of Japanese watches, Daini Seikosha and Suwa began the discussion of a product line that can match the quality of Swiss watches under the suggestion of the parent company. At the time, Suwa Seikosha Co. was in charge of manufacturing men’s watches, so it was decided that Suwa would be producing the first Grand Seiko (GS).
The first Grand Seiko was released in 1960, it was based on Seiko’s previous high-end watch, CROWN. This Grand Seiko has a 25-jewel, manual-winding, 3180 caliber, and only 36,000 units were produced. This was also the first chronometer-grade watch manufactured in Japan, and it was based on Seiko’s own chronometer standard.
Design style
The design language of the Grand Seiko was set in 1967, with the creation of Grand Seiko 44GS. The 44GS set the ground for all future Grand Seiko with nine elements. These elements help improve the legibility of the watch under different situations, and create a sharp, crisp visual impression:
- Double width index at 12 o’clock
- Multi-faceted rectangular markers
- Highly polished bezel
- Highly polished planes and two-dimensional surface
- Half recessed crown
- Flat dial
- Multi-faceted hour and minute hands
- Curved side line
- Reverse slanted bezel wall and case side
- Dress style with simple but beautiful design
- Zaratsu polishing
