Featuring Grand Seiko's distinct "Tough" Sport case design and highly accurate 9F86 GMT caliber, SBGN023 is the perfect grab-and-go watch for any adventure.
The stainless steel case features 20 bar of water resistance and has a magnetic resistance rating of 16,000 A/m (approx. 200 gauss), which is roughly three times the more common 4,800 A/m rating (60 gauss). The angular design of the case is highly ergonomic, and features an eye-catching blend of Zaratsu-polished and hairline-finished surfaces.
The black dial features bold, highly legible elements, from the contrasting color details and date window at four o’clock, to the sizeable indexes, hands, and their respective use of Lumibrite—a long-lasting, proprietary luminous paint that ensures nighttime visibility. A black ceramic bezel marked with a 24-hour scale frames the dial .
Powering the watch is Caliber 9F86, quartz caliber with a GMT function, a robust build, and an impressive accuracy of +/-10 seconds a year.
SBGN023 is a limited edition of 2,021 pieces marking the 140th anniversary of Seiko’s founding in 1881. The case back of the limited edition carries the Grand Seiko emblem in 18k yellow gold and the watch’s individual serial number.
