Grand Seiko Sport Collection Spring Drive GMT Rock-Pattern

SBGE 277

A Spring Drive GMT watch with a rock-pattern dial

All Grand Seiko Spring Drive timepieces are designed, made, assembled, and adjusted by the skilled craftsmen and women of the Shinshu Watch Studio, which is located in central Japan and surrounded by the Hotaka mountain range whose tallest summit is 3,190 meters high. As the Hotaka mountain range was created by volcanic activity, its peaks and slopes have sharp ridges and sheer cliffs which, even when carved by the wind and snow over the millennia, reveal nature at its most dramatic. The SBGE277 dial has the color and texture that typify the geology of the Hotaka range.

Thanks to Grand Seiko’s unique Spring Drive caliber, the second-hand glides silently and smoothly, with no ‘tick’, across the dial, perfectly reflecting the natural and continuous flow of time. The power reserve is 72 hours when fully wound and is shown on the discreet indicator next to the eight o’clock marker. The GMT hand on the SBGE277 allows a second-time zone to be shown and the hour can be adjusted without compromising the one-second-a-day precision of Spring Drive.
