Grand Seiko SBGH205

A Mechanical Hi-Beat 36000 with a Beautiful Form in Accordance with Seiko Style

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, encapsulating the past 41 years with high precision parts created using sophisticated modern technology assembled using skills inherited from the masters.
Innovations to the precision controlling mainspring, the hairspring, and the escapement (escape wheel and pallet) mean that the 9S Mechanical is not simply a revival of the 10-beat movement of the past, but its rebirth as a high-precision movement.
The accurate workings are ensconced in a beautiful exterior in the ‘Seiko Style’, which embodies the Grand Seiko design philosophy.
The black dial creates a strong impression with its ‘Mount Iwate pattern’, expressing the magnificence of the Mount Iwate mountainside visible from the Shizuku-Ishi Watch Studio where Grand Seiko mechanical watches are made.
The wearer can also enjoy watching the mechanical movement exquisitely mark out time through the transparent case back.
