History of Grand Seiko

For fifty years, the story of Grand Seiko has been the story of a team’s dedication to perfecting the deceptively simple idea of creating the ideal watch. Though times change and Seiko’s watchmaking technology has evolved rapidly, the spirit and essence of Grand Seiko has remained the same. For fifty years, Grand Seiko has stood for the same simple yet exacting ideals. And so it will be for the next fifty years. And beyond.


The first Grand Seiko

Grand Seiko was born. The first Grand Seiko model was produced in Suwa Seikosha (now Seiko Epson) in Nagano prefecture in central Japan.

Grand Seiko Self-dater

A second-generation model was launched, with a calendar function and with water resistance increased to 50 meters.


Daini Seikosha (now Seiko Instruments) produced its first Grand Seiko watch. It was the first model to embody the exterior design concept of 'Grand Seiko Style' which endures to this day.


The first Grand Seiko self-winding model. The crown was recessed and placed at the 4 o’clock position to dramatize the fact that hand winding was not required.


The first Grand Seiko automatic winding 10 beat model. This 10 beat caliber provided superior isochronism, and a high level of precision that made it more resistant to changes in position and external impact. The winding mechanism used SEIKO's original Magic Lever mechanism.


A manual 10-beat model, featuring a slimmer movement, like the automatic 61GS, it delivered a higher level of precision that made it more stable in different usage situations. The date calendar featured an instant-change mechanism.


The first Grand Seiko watch for women with a 10 beat, high precision movement.

61GS V.F.A.

V.F.A. stands for "Very Fine Adjusted." This super high precision model sought to explore the farthest limits of accuracy in a mechanical watch. It delivered a monthly rate of ± one minute or less.

45GS V.F.A.

V.F.A. stands for "Very Fine Adjusted." This super high precision model sought to explore the farthest limits of accuracy in a mechanical watch. It delivered a monthly rate of ± one minute or less.


After accuracy, size reduction was the next challenge for Grand Seiko. This caliber was automatic winding and although just 4.5mm height, it retained the high precision of its predecessors. Thinness was not just an engineer's challenge. "Easy to wear" was part of the "Best Basic" concept and this slimmer watch sat more easily on the wrist.

61GS Special

The Grand Seiko Special aimed for a yet higher standard of precision, more exacting even than the GS standard of the time.

19GS V.F.A.

Aiming for the highest possible precision in women's mechanical watches, this model delivered a monthly accuracy rate of ± two minutes.


The first "Grand Seiko" quartz model. It delivered accuracy of 10 seconds per year, 25 times higher than other regular quartz movements.


With water resistance of 10 bar, this model raised the practicability.


A Grand Seiko quartz model for women, also with 10 second-a-year accuracy.

9F8 series

'Quartz that surpasses quartz.' Pushing back the boundaries again, this quartz model set new standards of precision by incorporating systems like the 'backlash auto-adjust mechanism,' which had never before been achieved in a conventional quartz watch, a twin-pulse quartz mechanism and an instant calendar change mechanism.

9F6 series

The meticulous efforts of Seiko’s master craftsmen and women resulted in the mirror finish of the case side surface, free of distortion. It is also incredibly attractive and comfortable to wear.

9S5 series

The first new Grand Seiko mechanical caliber in twenty years. It set a new Grand Seiko standard, with cutting-edge production technology making possible a new interpretation of the traditional values of Grand Seiko.

9S56 series

For the first time in Grand Seiko history, this watch featured a fourth hand, showing GMT.

Reinforced magnetic resistance series

The launch of a quartz anti-magnetic watch, with 40,000A/m, a level of anti-magnetic protection that far exceeded all watchmaking norms.

9R6 series

The new and unique Spring Drive caliber is added to Grand Seiko. It delivers an accuracy rate of +/- 1 second per day.

9S67 series

A Mechanical caliber, delivering a long power reserve of 72 hours, is added.

9R8 series

The first Spring Drive Chronograph with vertical clutch, by far the most accurate luxury chronograph driven by a main spring.

9S8 series

An automatic winding 10 beat caliber, developed for Grand Seiko, the first in 41 years. The main spring and balance spring are made from the new, SEIKO-created, alloys SPRON 530 and 610 respectively.

9S65 series

A new automatic caliber with a power reserve of 3 days. Additionally, this model used the newest materials for its balance spring and escapement, improving the stability of its precision during actual use.

9S86 series

9S86 succeeds to the 10 beat caliber 9S85, which achieved superb accuracy even in everyday use by enhancing resistance to external shock.
A new added value caliber 9S86 was created by incorporating a GMT (Greenwich Mean Time) function into the 9S85 mechanical Hi-Beat 36000 platform.
