Product description
About this Grand Seiko watch
The Grand Seiko SBGY009 expresses Grand Seiko’s approach to precision and Japanese design through a deep-blue dial inspired by moonlight over 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 manual-winding Spring Drive delivers a power reserve of approximately 72 hours 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.
