Hi-Beat 36,000

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.

The movement is ensconced in a beautiful case with the stunning blue second hand contrasting with the white dial as it etches out precise time. In every detail, it is faithful to the ‘Grand Seiko Style’, the embodiment of the Grand Seiko design philosophy which started with the 44GS. The delicacy, strength and beauty of the movement can be enjoyed the exhibition case back.
