The history of striving to create the highest quality watches

In 1964, four years after the release of the first Grand Seiko, the Grand Seiko Self-Dater was created, with greatly improved practical performance. This became the model that clearly defined the direction of Grand Seiko from that point on.
The challenge of creating the highest quality watches continued, and in 1966, the Grand Seiko Standard, which was even more stringent than the chronometer standard set by the Bureaux Officiels de Contrôle de la Marche des Montres, was established, and in 1967, a design philosophy called the Grand Seiko Style was devised. Under this standard and this philosophy, Grand Seiko continues to evolve and develop as a unique brand.

Main Exhibits

  • 57GS Self-Dater

    57GS Self-Dater

    Released in 1964, the 57GS Self-Dater featured a date display with Seiko’s patented “quick-set date correction mechanism” and was the first Grand Seiko to use stainless steel for the case. Known as the “Grand Seiko Second” for its practicality and elegance, it marked a milestone in the philosophy of Grand Seiko’s relentless evolution in practicality.

  • 62GS

    62GS

    The 62GS, born in 1967, was the first Grand Seiko model to feature an automatic mechanical movement. It was equipped with a second hand regulation device, fine adjustment mechanism, and waterproof structure, meeting the stringent “Grand Seiko standards,” which are even stricter than the chronometer standard set by the Bureaux Officiels de Contrôle de la Marche des Montres. By eliminating the bezel, it allows more light to enter from the sides of the raised glass, making the hands and indexes on the dial shine brilliantly in the light.

  • 44GS

    44GS

    Released in 1967, the 44GS established the unique design grammar of Grand Seiko, known as the “Grand Seiko Style,” born from Japanese aesthetics. Its most notable feature is the sharp, distinctive beauty achieved by connecting the flat and straight surfaces polished with “Zaratsu polishing” with ridgelines, emphasizing the surfaces.

  • 61GS

    61GS

    The 61GS, completed in 1968, was Japan’s first 10-beat model, achieved through high-level innovative technology and high productivity. The high-beat movement excels in isochronism, providing more stable high accuracy against positional differences and external disturbances. It also features Seiko’s unique “Magic Lever” automatic winding mechanism, significantly improving winding efficiency.

  • 45GS V.F.A.

    45GS V.F.A.

    “V.F.A.” stands for Very Fine Adjusted, representing an ultra-high-precision watch with an unprecedented “monthly accuracy of ±1 minute” in mechanical watches.
    The “45GS V.F.A.” was born in 1969, equipped with the hand-winding caliber 4580, with a balance wheel that oscillates 10 times per second. It is the pinnacle of Seiko’s mechanical watch movements, officially certified as a Chronometer by the Neuchâtel Astromical Observatory.

  • 61GS Special

    61GS Special

    In 1970, the Grand Seiko Special Standard was established, which set an even more stringent standard of accuracy than the Grand Seiko Standard, and the 61GS Special was released based on this standard. With a mean daily rate of just +3 to -3 seconds, this watch boasted the highest level of accuracy, other than the V.F.A. models, which have a limited production quantity due to requiring very careful assembly and adjustment.
