Grand Seiko Sport Collection SBGE257 Spring Drive GMT Green Dial
The Grand Seiko SBGE257 is a Sport Collection Spring Drive GMT watch featuring a deep green dial, matching green ceramic bezel, and contrasting yellow 24-hour GMT hand. It combines a compact 40.5 mm stainless-steel case with Grand Seiko’s high-precision Caliber 9R66 movement.
The dial includes LumiBrite hands and hour markers, a date display, GMT function, and power-reserve indicator. The dual-curved sapphire crystal has an anti-reflective coating on the inner surface, while the screw-down crown is positioned at 4 o’clock. The stainless-steel bracelet is secured by a three-fold clasp with push-button release.
Spring Drive provides approximately 72 hours of power reserve and an average accuracy of ±15 seconds per month. With 20-bar water resistance, magnetic resistance of 4,800 A/m, and a fixed ceramic bezel with 24-hour scale, the SBGE257 is a practical travel watch with distinctive Japanese design character.
