Evolution 9 Collection SLGW007

This 36,000 vibrations per hour (5 Hz), manual-winding mechanical watch is based on the “Evolution 9 Style,” a unique design grammar that takes the fusion of Grand Seiko’s spirit with the aesthetic sensibilities of Japan to a higher level. Its textured, navy-colored dial evokes the bark of a white birch tree illuminated by the moon. Featuring a slender stainless steel case that is a mere 9.95mm thick, the creation has an appearance worthy of a Grand Seiko dress watch. The manual-winding movement is the Caliber 9SA4, which features a high number of 36,000 vibrations per hour (5 Hz), to maintain a stable level of accuracy, as well as a generous power reserve of up to 80 hours.
