Product description
About this Grand Seiko watch
The Grand Seiko SBGE255G expresses Grand Seiko’s approach to precision and Japanese design through a compact black-and-blue ceramic bezel and a GMT display designed for a second time zone. A 40.5 mm stainless steel with ceramic bezel case with dual-curved sapphire crystal balances visual refinement with everyday wearability.
Inside, the Calibre 9R66 Spring Drive GMT 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 an independently useful second-time-zone display and 20 bar water resistance. It is a strong choice for collectors seeking Grand Seiko precision in a practical luxury sports watch.
