A textured blue dial evokes a moonlit birch tree in this manual-winding, 10-beat mechanical timepiece
This 10-beat, 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-coloured 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 bezel is refined, with a narrow profile that complements the lugs, whose clean lines are echoed on the dial by the indexes. The manual-winding movement is the Calibre 9SA4, which features a high number of vibrations, 10 per second, to maintain a stable level of accuracy, as well as a generous power reserve of up to 80 hours.
