About Grand Seiko SBGM245
Grand Seiko Sport Collection
GMT and sports. A perfect combination.
The GMT hand allows the time to be read in a second time zone and the hour hand can be adjusted without compromising the watch’s accuracy. This dual-time capability is the perfect function for the world traveler and is here available in a high-performance sports watch. The hour and minute hands are substantial and carry LumiBrite so as to be easily legible, day and night. The GMT hand is in red and has a distinctive shape that makes it readable at a glance against the deep blue dial. The screw-down crown is recessed at the four o’clock position for extra security and the watch is water resistant to 20 bar. All this, in a case that is just 40.5 mm in diameter. The convenience of GMT meets the high functionality of a true sports timepiece. Quite a combination.

Grand Seiko SBGM245 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.
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
