The Strat-o-timer Titanium Diver GMT was designed to be a tool watch, taking the brand's flagship model and placing it the dive watch category. The 40mm shaped case and 7-link bracelet remains as identifiers of the Strat-o-timer platform, but is given an alternative identity with its full Grade 2 titanium case and bracelet. The bezel is equipped with a circular brushed ceramic bezel with a traditional dive marking layout. Inside is the Miyota 9075 GMT movement that features an independently jumping local hour hand, regulated in-house to +/- 5 seconds per day. The bezel, dial, and handset feature Grade A BGW9 to ensure long lasting glow. With a vision of becoming a legacy brand in our home state of Texas, the Strat-o-timer is assembled, and the movement regulated, in the USA.
