Grand Seiko 9S Mechanical Mens Watch SBGJ203G

Grand Seiko 9S Mechanical Mens Watch SBGJ203G

This model incorporates Caliber 9S86, the high-specification movement that delivers the same accuracy (-5 to +3 seconds a day) and the same power reserve (55 hours) as the core Caliber 9S85. A beautifully delicate and polished finish has been created on the dial, with a 'Mount Iwate pattern', inspired by the many-ridged contours of the Mt. Iwate, the mountain that is visible through the windows of the Shizuku-Ishi Watch Studio where Grand Seiko mechanical watches are made.
