Grand Seiko Evolution 9 White Birch Forests

With its intricate pattern and life-imbued green coloring, 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, this movement achieves a high frequency of 36,000 vibrations per hour while offering an impressive power reserve of approximately 80 hours when fully wound. Both the case and bracelet are made of Ever-Brilliant Steel, which shines whiter than conventional stainless steel while offering exceptional corrosion resistance.
