About Grand Seiko SBGR001
Grand Seiko Automatic Collection
“Our goal was to create the best possible mechanical watch for everyday use.”
This was the vision. Caliber 9S inherits the spirit of the first Grand Seiko from 1960; a timepiece crafted to the same exacting standards as the very best chronometers of its time.
Incorporating both the very latest in watchmaking technology and the finest craftsmanship, Caliber 9S offers high precision and reliability that endures.
The accuracy of a mechanical watch depends greatly on the precision of its hundreds of individual parts. This is why all the components of each Grand Seiko watch are made by Seiko in-house and to the same high standards. To ensure the very highest levels of precision, certain key parts are made using Micro-Electro-Mechanical Systems (‘MEMS’), a cutting-edge manufacturing technology originally developed for semiconductors.
It takes more than a collection of precision parts to make a masterpiece. To reach the strict accuracy standards of Grand Seiko, key parts are individually polished and fine-tuned with great care by elite craftsmen and women to an accuracy of 1/1,000th of a millimeter before being assembled into a complete timepiece.
Seiko is proud of being a true manufacture for over a century. Grand Seiko’s Caliber 9S is the pinnacle of Seiko’s watchmaking today, offering the very best watches for everyday use. The vision is now a reality.
About 9S Mechanical
In 1968, Grand Seiko introduced Japan’s first automatic 10-beat watch (61GS) to the world.
In 2009, 10-beat Caliber 9S85 surpassed the original, with high precision parts created using sophisticated modern technology assembled with skills honed over the many decades of Grand Seiko’s watchmaking.
Innovations to the precision controlling mainspring, the hairspring, and the escapement mean that the 9S Mechanical is not simply a revival of the 10-beat movement of the past, but an entirely new incarnation of this high-precision movement.

Grand Seiko SBGR001 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
