Grand Seiko Evolution 9 Collection Single Winding with Manual Winding 40mm Watch

With its intricate pattern and silvery white hue, the watch’s dial dynamically expresses the white birch forests that grow in profusion near the Grand Seiko Studio Shizukuishi, the manufacturing base for Grand Seiko’s mechanical watches. Inside is the mechanical high-beat Caliber 9SA5, a Grand Seiko-exclusive automatic movement. Thanks to its innovative Dual Impulse Escapement and twin barrels, it delivers a high frequency of 36,000 vibrations per hour and an impressive power reserve of approximately 80 hours when fully wound. Both the case and bracelet are made of Ever-Brilliant Steel, which shines brighter than conventional stainless steel while offering exceptional corrosion resistance.
