The first Grand Seiko from the Micro Artist Studio – Spring Drive, 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 the new caliber 9R01 Spring Drive with an eight-day power reserve.
This is 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%.
The case material is rare platinum 950, a blend containing 95% platinum. The newly developed Zaratsu 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, near the studio, a unique composite finish that ensures high-visibility and glistens as it catches the light.
