A continuing story of craftsmanship and innovation Since making its first wrist fake watches UK in 1913, Seiko has continuously refined its mechanical watchmaking skills and, today, makes every component, including mainsprings and balance springs, in-house.

As a true ‘manufacture’, and inspired by the founder, Kintaro Hattori’s vision that Seiko should always be one step ahead of the rest, the story of Seiko’s mechanical watchmaking is one of constant innovation.
The 9S family of calibers is the latest embodiment of Seiko’s relentless pursuit of perfection.
