Grand Seiko Heritage Replica Watch SBGH201

Description

Grand Seiko Heritage

A complete and beautifully formed Mechanical Hi-Beat 36000

In 1968, Grand Seiko introduced Japan’s first automatic 10-beat watch (61GS) to the world. In 2009, 10-beat Caliber 9S85 surpassed the original, with high precision parts created using sophisticated modern technology assembled with skills honed over the many decades of Grand Seiko’s watchmaking.

Innovations to the precision controlling mainspring, the hairspring, and the escapement mean that the 9S Mechanical is not simply a revival of the 10-beat movement of the past, but an entirely new incarnation of this high-precision movement.
