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.
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.
Case : Stainless steel
Case back: Stainless steel and sapphire crystal
Glass : High definition dual-curved sapphire crystal Coating : Anti-reflection coating on inner surface Case size : Diameter 40.2mm×Thickness 13.0mm Band : Stainless steel
Movement : Caliber 9S85 Driving system : Automatic Power reserve : Approximately 55 hours Accuracy : +5 to -3 seconds per day (when static)
Note: This accuracy is the result of measuring the loss/gain of the time for seventeen days before the inside movements of the watch are put in the case. The measurement has been done in the factory where temperatures or position of the movements are controlled. When the watch is actually worn, the accuracy should be from -1 second/day to +10 seconds/day (-1 second/day to +8 seconds/day for Cal.9S85, 9S86).
Clasp : Three-fold clasp with push button release Water resistance : 10 bar Magnetic resistance : 4800 A/m (60 gauss) Weight : 151.0 g Remarks : ・Screw down crown
