Grand Seiko Heritage Collection
Quartz watch 50th Anniversary Limited Edition
Fifty years ago, the world’s first quartz watch, the Seiko Quartz Astron, was launched. Perhaps no watch before or since has had a more important or lasting impact on the watch industry, as it marked the start of the quartz revolution which brought high precision timekeeping within the reach of all. To commemorate the Quartz Astron’s 50th anniversary, we are proud to announce a limited edition Grand Seiko watch which has a unique design and Grand Seiko’s latest quartz movement, the GMT caliber 9F86. This limited edition watch takes center stage within the Heritage Collection.
The case is classically Grand Seiko, polished to a beautiful distortion-free mirror finish. The dial is in Grand Seiko’s signature deep blue color and carries a pattern based on the quartz crystal symbol that was used for many years on Seiko’s quartz watches and acts as a quiet reminder of the Quartz Astron’s importance to modern horology.
The seconds and GMT hands are in gold, as are the 24 hour numerals inside the minute track and the name Grand Seiko.
The case back carries the Grand Seiko lion, the symbol of Grand Seiko. Alongside are the quartz crystal symbol and the words ‘Quartz Watch 50th Anniversary’. Each watch in this limited edition of 2019 has its own serial number which is also displayed on the case back.
The alignment of the case back might be different from that shown in the photograph.
Limited edition of 2,019 pieces.

Grand Seiko SBGN009 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
