A Spring Drive gem inspired by Omiwatari
Most winters, 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 Gods walk out over the ice.
True or not, the legend has inspired the craftsmen and women at the nearby Shinshu Watch Studio to create a dial of exquisite subtlety for this hand-winding Spring Drive timepiece. It has the colour, feel and texture of the snow-covered ice on Lake Suwa.
The movement is Spring Drive Calibre 9R31 which has the Dual Spring Barrel that delivers a power reserve of 72 hours when fully wound. Its exquisite finishing is visible through the exhibition case-back along with the power reserve indicator.
