A dial inspired by sunlight shimmering on an early morning frost. Winter arrives suddenly in Shinshu, the region that is home to the facility where all Grand Seiko Spring Drive watches are created. Frost forms at night on the trees and, for a brief but beautiful moment, glistens in the still powerful morning sun before melting away. The fleeting beauty of this phenomenon is captured in this dial. Thanks to Grand Seiko’s unique Spring Drive movement, the seconds hand glides silently and smoothly, with no tick, across the dial, perfectly reflecting the natural and continuous flow of time. The power reserve is 72 hours when fully wound and is shown on the discreet indicator next to the eight o’clock index.
