DESIGN

A blue dial with a ‘Mount Iwate pattern’

The blue dial—which features a ‘Mount Iwate pattern’ showing the ridgelines of the magnificent mountain visible from the Shizukuishi Watch Studio where all Grand Seiko mechanical timepieces are made— expresses the beauty of winter mountain scenery emerging faintly through moonlight reflected on snow.

A see-through case back so you can fully enjoy the beautiful mechanical movement

The words “Grand Seiko Boutique Limited Edition” are displayed proudly on the sapphire glass case back, which also is marked with the Grand Seiko lion emblem.

MOVEMENT

MECHANICAL HI-BEAT 36000 GMT Caliber 9S86

This high-specification movement delivers the same accuracy (+5 to -3 seconds a day) and the same power reserve (55 hours) as the core Caliber 9S85, while also offering the GMT function that the international traveler needs to ensure that the accuracy of the time shown is not compromised when the time zone is changed. The GMT hand shows the time in the home time zone.

Pulling the crown out by one notch enables the hour hand to be adjusted without stopping the second hand so that the highly accurate timekeeping delivered by the Hi-Beat 36000 is not lost. Caliber 9S86 is the embodiment of the Grand Seiko ideal of high accuracy, maintaining exceptional precision in both the essential time display and the GMT function.

Grand Seiko SBGJ235G 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:

1. Double width index at 12 o’clock
2. Multi-faceted rectangular markers
3. Highly polished bezel
4. Highly polished planes and two-dimensional surface
5. Half recessed crown
6. Flat dial
7. Multi-faceted hour and minute hands
8. Curved side line
9. Reverse slanted bezel wall and case side
10. Dress style with simple but beautiful design
11. Zaratsu polishing
