Grand Seiko 60th Anniversary Limited Edition (SBGR321)
Made in celebration of the Grand Seiko watch brand’s 60th anniversary, this new limited edition (reference SBGR321) draws inspiration from the nature that surrounds the two studios, in Shizukuishi and Shinshu, where all its timepieces are crafted.
The dial of the new limited edition automatic watch recreates the brilliant blue sky over Mt. Iwate at dawn when it is tinged with the red of the morning sun. 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 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.
The Grand Seiko SBGR321 watch houses the 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.
This new watch is a limited edition of 2,500 pieces and will be available worldwide in October, 2020.
