In 2021, the Grand Seiko collection expanded to include a watch equipped with a mechanical movement of the highest quality, Caliber 9SA5. This movement was introduced last year in limited editions but is now offered in the mainstream collection. This watch expresses perfectly the Grand Seiko philosophy and clearly indicates the way forward.
Grand Seiko Heritage Collection SLGH005. Stainless steel case (diameter 40 mm) and bracelet, automatic, see-through case back. The watch is powered by the new Caliber 9SA5, the highest-performing hi-beat automatic movement ever made by Grand Seiko. Featuring sturdiness and high precision coupled with excellent finishing and a unique look.
Caliber 9SA5, the new automatic high beat movement, took the watch industry by storm in 2020. With a power reserve of roughly 80 hours in addition to a new mechanism comprising the precision-boosting Grand Seiko free-sprung balance, a new overcoil, and a dual-impulse escapement, this advanced automatic high beat movement ranks among the world’s top calibers. The uniqueness of the mechanism makes it the best automatic movement available in all price ranges.
