Grand Seiko Heritage Spring Drive SBGA465G 40.0 mm Steel Silver Dial Watch for Men

Winter arrives suddenly in Shinshu, where every Grand Seiko Spring Drive watch is made. Frost forms on the trees overnight and glistens briefly in the morning sun before it melts. The SBGA465G captures that fleeting moment in a silver dial with an organic, pressed pattern, set in Grand Seiko's classic Heritage case.

The Spring Drive calibre 9R65 moves the seconds hand in a silent, continuous glide and runs for about 72 hours when fully wound, with the remaining reserve shown next to the eight o'clock index. The 40.0 mm stainless steel case and bracelet sit under a dual-curved sapphire crystal, with a screw case back and 10 bar water resistance.
