About this Grand Seiko watch
The Grand Seiko SLGB025G expresses Grand Seiko’s approach to precision and Japanese design through a green Ushio dial inspired by tranquil shallow coastal waters. A 40.8 mm high-intensity titanium case with sapphire crystal balances visual refinement with everyday wearability.
Inside, the Calibre 9RB1 Spring Drive U.F.A. delivers a power reserve of approximately 72 hours (3 days) and official accuracy rated at ±20 seconds per year (±3 seconds per month), complemented by 300m / 1000ft diver's water resistance. It is a considered choice for collectors seeking distinctive Japanese design and accomplished Grand Seiko watchmaking.
