Description

A Grand Seiko Spring Drive masterpiece from the Micro Artist Studio with an eight-day power reserve.

The 9R Spring Drive 8Days is driven by a Spring Drive, and the first Grand Seiko to be produced by the specialists in high quality watches at the Micro Artist Studio in Seiko’s facility in Shiojiri, near Nagano.

It contains caliber 9R01 Spring Drive with an eight-day power reserve made possible by an innovative approach to the barrel which preserves power by controlling the mainspring. The existing Spring Drive caliber contains one barrel, but the caliber 9R01 has three that are linked together, extending the usage time given from each wind by over 250%.

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 a specially adapted Zaratsu technique.

Grand Seiko: beautifully, precise Japanese watchmaking, from the pinnacle of Seiko Watch Corporation’s in-house manufacture. Every Grand Seiko features signature high standards of Japanese precision, durability and legibility, handcrafted by Takumi artisans.
