Grand Seiko Heritage Collection SBGR317 Automatic Black Dial Watch
The Grand Seiko SBGR317 is a Heritage Collection mechanical watch with a black dial, stainless-steel case, and automatic Caliber 9S65 movement. It combines a contemporary 40 mm case with Grand Seiko’s distinctive, highly finished design language.
The automatic movement offers approximately 72 hours of power reserve, with manual winding and a stop-seconds function. The black dial features a fine radial texture, multi-faceted three-dimensional indexes, a date display, and faceted hands. The case is fitted with dual-curved sapphire crystal and an inner anti-reflective coating.
The stainless-steel bracelet uses a three-fold clasp with push-button release. A screw-down see-through caseback displays the mechanical movement and Grand Seiko lion emblem. Water resistance is rated at 10 bar.
