Grand Seiko

Discover the long-lasting precision and Japanese aesthetic of Grand Seiko.

Honoring our origins,

Embracing our Future

It was the determination to excel that brought about the birth of Grand Seiko in 1960. During its development and ever since, the idea that drove the designers and engineers was that Grand Seiko should be the ‘ideal’ watch with standards of precision, durability and beauty that would lead the world.

The development of Grand Seiko quartz

Grand Seiko's first quartz watch

In 1988, the first Grand Seiko quartz watch, the 95GS was born. It far exceeded the performance of all regular quartz watches with its accuracy of ±10 seconds per year. The secret, as ever with Grand Seiko, was the ability to manufacture every component in-house. Using quartz crystals grown in its own facilities and in its own way, the Grand Seiko team was able to select only those oscillators that exhibited superior performance in temperature resistance, humidity resistance and shock resistance, to produce movements with the highest possible accuracy.

A new mechanical movement with manual winding,

high-beat precision, and 80 hours of power.

Grand Seiko’s new Caliber 9SA4 is its first manually wound, 10-beat mechanical movement in over 50 years. Making its debut in a new dress watch in the Evolution 9 Style, the svelte, high-beat Caliber 9SA4 has a power reserve of 80 hours despite measuring just 4.15mm thick. Engineered for the best possible sound and feel during winding, the new movement is also highly efficient, requiring 15 percent fewer crown rotations than Caliber 9SA5, released in 2020, to achieve the same 80-hour duration when wound by hand.
