The dial inspired by white birch forests at night.
This Hi-Beat 36000 watch shares the same Evolution 9 design as the celebrated ‘White Birch’ SLGH005 but is presented with a black dial that captures the atmosphere of the white birch tree forests on the Hiraniwa Plateau at night. These forests cover some 400 hectares and are located near the studio in Shizukuishi where all Grand Seiko mechanical watches are crafted.
Its powerful hands and grooved, prominent markers ensure perfect legibility. Its Zaratsu polished, distortion-free mirror finish and delicate hairline finish alternate to give the case a quiet and harmonious glow. The case has wide lugs and a low center of gravity that ensure that the watch sits easily and securely on the wrist.
This high-beat watch is powered by the revolutionary Caliber 9SA5, which offers a power reserve of 80 hours thanks to the high efficiency of Grand Seiko’s unique Dual Impulse Escapement and the high power generation of the twin barrels.
