Hazard 4® Heavy Water Diver® watches glow continuously using self-powered tritium (H3) Swiss mini-lamps like in your pistol night sights - won’t fade overnight like luminescent paint. A Swiss-movement guarantees reliable accuracy. Built with 100% titanium, this 50mm large watch is only 1/2 the weight, but double the strength of a steel watch. A proven dive watch, it is water resistant to 300M / 990 FT depth. The unique, bold, military styling features easy-to-read numerals and our exclusive integrated 24-hour scale. The submarine-inspired aesthetics carry into the precision, 60-click uni-directional dive bezel topped with tritium zero indicator and the easy-turn screw-down crown. The face numerals are 3D stencil 2-layer design which along with angled chapter ring makes it not only tactical, but also a sophisticated timepiece suitable for the office or formal event. Available in an unprecedented range of tactical and urban oriented colors/finishes - they come equipped with a variety of straps and bracelets. Used in the most extreme environments by special forces, explorers, and professionals worldwide, it won’t let you down and makes an unforgettable formal present.
