SBGY007 - A Spring Drive gem inspired by "Omiwatari"

Every winter, the water of Lake Suwa freezes over, and most years a long ridge appears in the ice from one side of the lake to the other. Tradition has it that this is the "Omiwatari," or where the Shinto Gods walk out over the ice.his legend has inspired the craftsmen and women at the nearby Shinshu Watch Studio to create SBGY007.

The dial here is ice-blue in color and textured to mimic the undulations of the frozen lake. Inspired by the shape of a wind-filled sail, the stainless steel case measures 38.5mm across and was designed to easily slip under a shirt cuff.? new adaptation of Zaratsu polishing was developed to address the challenge of creating a distortion-free finish on a curved surface.

Housed inside the case is caliber 9R31, which has a Dual Spring Barrel that delivers a power reserve of 72 hours when fully wound. Beautifully finished and visible through an exhibition case back, 9R31 also carries the power reserve indicator over from the dial to the movement.
