The brilliant blue sky over Mt. Iwate at dawn that greets the watchmakers and technicians of the Grand Seiko Studio Shizukuishi is a sight to behold, especially when it is tinged with the red of the morning sun. It is this combination of colors that has inspired the design of this new automatic timepiece. The blue of the dial is echoed in the vivid blue of the titanium sections of the oscillating weight and a red ring inside the sapphire crystal case back mirrors the glow of the morning sun as it rises and causes light to flood through the broad windows of the studio.
The watch is powered by Caliber 9S65 which delivers a power reserve of 72 hours and a precision rate of 5 to -3 seconds a day. It is assembled, adjusted and inspected by hand at the recently opened Grand Seiko Studio Shizukuishi from where Mt Iwate’s inspiring and graceful form is clearly visible.
The blue of the oscillating weight is achieved through an anodic oxidation process in which metals are subjected to electrolysis so as to generate an oxide film. This oxide film produces color according to the light refraction index when the thickness of the oxide film is carried.
Calibre 9S65:
Caliber 9S65 is the most standard automatic movement that typifies the 9S mechanical series. The old and new movements may appear to have a similar design, but they are utterly different in terms of performance.
Grand Seiko has not only revised the materials used to make this movement, but also applied MEMS (Micro Electro Mechanical System) technology, which utilizes semi-conductor manufacturing technology, to the production of the watch parts. Grand Seiko has significantly enhanced the basic performance of this timepiece, and has also redesigned the way in which the oscillating weight winds the mainspring.
The winding system of its predecessor, Caliber 9S55, used Grand Seiko’s Magic Lever mechanism. By contrast, Caliber 9S65 uses reverser gear train system. Hardening the components has helped improve the durability of the reverser system, which had been a weakness.
