Masterpiece Collection

A Spring Drive classic, with an eight day power reserve

Caliber 9R01, created by the Micro Artist Studio, shows the full potential of Spring Drive at its very best. Not only does it offer a remarkable precision rate of 10 seconds per month but it also delivers a power reserve of eight days, thanks to the use of three barrels, to the unique design of the movement and to the craftsmanship of its manufacture.

This watch presents the beauty of Japan, inspired by the night sky in the mountains that surround the Micro Artist Studio. The 18k rose gold case frames a black dial through which the stars twinkle just as they do on a clear dark night in central Japan, adding extra depth and richness to the dial. Thanks to a special process that combines both plating and painting, the dial has a fascination all of its own. As if sprinkled with stardust, the dial is at once mysterious and yet perfectly legible, thanks to the deep black of the background, the sparkles of the stars that shine out from it and the five-faceted profile of the hands and hour markers. The razor edge polishing of the hands and markers gives this creation the unique Grand Seiko signature, as does the exquisitely sharp mirror finish achieved by our new Zaratsu technique that was
developed for the platinum version.
