Sport Spring Drive GMT

From the retailer listing

A Spring Drive GMT with a verdant new green dial Inspired by the rich green forests that can be seen in the high mountains that surround the Shinshu Watch Studio in central Japan, this new Grand Seiko reference delivers both drama and richness in color, with high performance and all the globe-trotting capability of the maker's state-of-the-art Spring Drive movement. Thanks to Grand Seiko's proprietary Spring Drive caliber, the seconds 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 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.
