The first Grand Seiko from the Micro Artist Studio – Spring Drive, with an eight-day power reserve
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.
