From Grand Seiko, presenting the Spring Drive (ref. SBGD205), a distinctive model that balances proportion, precision, and presence. On the wrist, the case feels purposeful: crafted in platinum and measuring 43 mm in diameter, with a thickness of 13.5 mm, defined by a round silhouette. The caseback is open, and the crystal is sapphire, delivering water resistance to 10000 meters.
