Grand Seiko Sport Collection SBGM247 Mechanical GMT Green Dial Watch
Grand Seiko Sport Collection SBGM247 Mechanical GMT Green Dial Watch
The Grand Seiko SBGM247 is a mechanical GMT watch from the Sport Collection, combining a hunter-green sunray dial with a distinctive orange GMT hand. Its 40.5 mm stainless-steel case, fixed 24-hour bezel, and 20 bar water resistance give it a practical sports-watch profile.
The watch is powered by Grand Seiko’s automatic Caliber 9S66, which offers approximately 72 hours of power reserve, manual winding, and independent local-hour adjustment for convenient travel between time zones. The dual-curved sapphire crystal has anti-reflective coating on the inner surface, while LumiBrite hands and indexes support low-light legibility.
The SBGM247 is fitted with a stainless-steel bracelet and a folding three-fold clasp with push-button release. Additional features include a screw-down crown, screw caseback, date display, 24-hour GMT function, and magnetic resistance of 4,800 A/m.
