Specifications

About this reference

This model’s case design has evolved with a sporty character based on the Evolution 9 Style, a design language that represents a step forward for the Grand Seiko Style. The watch’s dial captures the serene beauty of a snowy moonlit night over Mt. Iwate, as seen from the Grand Seiko Studio Shizukuishi, the home of Grand Seiko’s mechanical watchmaking. The movement inside is the Caliber 9SC5, Grand Seiko’s first mechanical chronograph “Tentagraph.” Even with its 10-beat frequency, this movement achieves an impressive power reserve of approximately 72 hours (about three days) when fully wound.
