G-shock GN-1000B-1A From the GULFMASTER Series of watch designed and engineered to stand up to the rigors of maritime wear comes new collection of Twin Sensor models. A digital compass takes continuous readings for 60 seconds to help find your bearings at sea, while a Moon age indicator shows a graphic representation of Moon data. A hand shift feature temporarily moves hands out of the way with the press of a button for easy reading of digital display contents. The soft band creates a secure fit around the entire case to form smooth-flowing lines. This also serves to relieve band tension and provide a comfortable fit to the wrist. The result is useful and highly practical functions packed into a form that maintains its comfort, even after long hours of wear. From functionality to design, everything about these new GULFMASTER models supports the men of the sea and their activities in harsh environments.
