Inspired by the clear blue sky as seen from the top of Mt. Iwate
A limited-edition watch commemorating the 25th anniversary of the Caliber 9S mechanical movement.
Its design depicts the clear blue sky as seen from the top of Mt. Iwate, the soaring peak visible through the windows of the Grand Seiko Studio Shizukuishi, where Grand Seiko mechanical watches are assembled. A classic form prevails thanks to this creation’s mirror-finished bezel and case, gently curved lugs with Zaratsu polishing, and a box-shaped sapphire crystal. Inside is the Grand Seiko Caliber 9S66.
Assembled at the Grand Seiko Studio Shizukuishi by skilled craftsmen and women, the self-winding Caliber 9S66 is a GMT movement that runs for approximately 72 hours when fully wound.

Grand Seiko SBGM253 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
