El primer Grand Seiko from the Micro Artist Studio – Spring Drive, with an eight-day power reserve

The 9R Spring Drive 8Days is a complex watch 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 Shiojiri, Nagano.

It contains the new caliber 9R01 Spring Drive with an eight-day power reserve, far surpassing the three days given by previous models.

This is made possible by an innovative approach to the barrel which preserves power by controlling the mainspring. Usually a Spring Drive contains one barrel, but the caliber 9R01 has three that are linked together, extending the usage time given from each wind by over 250% longer than any previous watch.

The case material is rare platinum 950, a blend containing 95% platinum. The newly developed Sallaz polishing technique has also been used on this model to give the case a sharply defined edge and exquisite finish never before seen on a platinum case.
The pure white dial has a glittering diamond-dust effect reminiscent of a winter morning in the Suwa region, a unique composite finish that ensures high-visibility and glistens as it catches the light.
