From the Gulfmaster Series - designed and engineered to stand up to the rigors of maritime wear - comes a new collection of Twin Sensor models.
A digital compass takes continuous readings for 60-seconds to help find your bearings at sea and a thermometer feature helps to keep you informed about the environment around you. A Tide Graph feature lets you check tide conditions whenever you want, while a Moon age indicator shows a graphic representation of Moon data. Both of these functions also support activities on the sea.The soft urethane 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.
