Grand Seiko Evolution 9 Collection High Beat “White Birch”

This timepiece is inspired by the beauty of the Shizukuishi region in Japan, where Grand Seiko mechanical movements are created. The design represents the Nature of Time – a uniquely Japanese spirituality where time is viewed as nature itself with each fleeting moment, minute and second a unique expression, unveiled through light and shadow.

The dial pattern echoes the beauty of the white birch forests which surround the Grand Seiko Shizukuishi studio – minimalism that belies its supremely efficient hi-beat movement – the finest mechanical calibre that Grand Seiko has ever created, the 9SA5. In 1998, the 9S mechanical movement opened a new chapter in the Grand Seiko story, this new calibre represents a watchmaking advance just as important. 9SA5 is an entirely new movement with a power reserve increase from 55 hours to 80 hours compared to our previous hi-beat movements and a 15% slimmer design which is both more accurate and robust.

This timepiece is within the ‘Evolution 9’ or ‘Kyu’ collection – watches which epitomise the Grand Seiko endeavour to create the most precise, durable, wearable and beautiful watch possible. ‘Kyu’ in Japanese means both 9 – the highest number possible – and ultimate, representing the aim for the ultimate in watchmaking.

Grand Seiko: the relentless quest for precise timekeeping from the pinnacle of Seiko Watch Corporation’s in-house manufacture. With leading watchmaking, durability and legibility, every Grand Seiko is still handmade in Japan by elite craftsmen and women.

Calibre 9SA5:

After the wide acclaim given over many years to the Calibre 9S series of mechanical movements, it had long been Grand Seiko’s goal to push the boundaries back further and create a new mechanical movement with enhanced performance, just as the first 9S movement had done two decades before. The decision was taken to aim for a new 10-beat movement that would offer a greatly increased power reserve. This is how Calibre 9SA5 was born.

Calibre 9SA5 is the direct result of the synergy of these two important assets, as its advanced functionality and its exquisite craftsmanship bear powerful testament.
