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 Calibre 9S85 surpassed the original, with high precision parts created using sophisticated modern technology assembled with skills 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.
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 black dial creates a strong impression with its ‘Mount Iwate pattern’, a delicate and beautiful radial pattern, inspired by the many-ridged contours of the Mt. Iwate, the mountain that is visible through the windows of the Shizuku-Ishi Watch Studio where Grand Seiko mechanical watches are made.
The delicacy, strength and beauty of the movement can be enjoyed the exhibition case back.

The three movements at the heart of Grand Seiko
One of the world's foremost mechanical movements, the culmination of high-precision micro-engineering and the attention to detail of Seiko's expert watchmakers.
Spring Drive is a unique movement that delivers one-second-a-day precision, using just the power of a mainspring.
