Product description
About this Grand Seiko watch
The Grand Seiko SBGY011 expresses Grand Seiko’s approach to precision and Japanese design through an Asaborake dial inspired by dawn mist lifting from the Shinshu mountains. A 40.0 mm stainless steel case with box shaped sapphire crystal balances visual refinement with everyday wearability.
Inside, the Calibre 9R31 Spring Drive Manual winding delivers a power reserve of approximately 72 hours (3 days) and official accuracy rated at ±15 seconds per month (±1 second per day), complemented by 10 bar water resistance. It is a considered choice for collectors seeking distinctive Japanese design and accomplished Grand Seiko watchmaking.
