HWD - Arid

titanium tritium dive-watches

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.

Great looking watch!Review by JAMES
Great looking watch. Haven't had it long enough for a quality review. I wish the date was about twice the size it is. Hard to read. Will probably need an additional band which I have tried to purchase but apparently they are not available yet. Was strictly a Luminox fan until purchasing this watch. Will have to see if over time it holds up as well. (Posted on 7/25/2018)
Great Style, beautiful design, lightweight modern materialsReview by Michael
I've wanted one ever since I saw the Ad in Recoil Magazine. I thought it was out of my price range being a Paramedic. I finally had the opportunity to purchase one and couldn't be happier. I love it. It's ultra light case, comfortable band, I love the way the end of strap secures with locking tab. The watch stays securely in place. The uni-directional bezel turns with positive smooth clicks that just feel like quality. 3D numbers on dial are unique and easy to read.The details and finish of machine work is smooth and perfect. PVD coating is also silky smooth. Highly recommended watch for EMS, Tactical, or just collectors. (Posted on 9/24/2017)

Would love to see the HWD offered with an automatic, self winding movement as opposed to quartz.
it's in the works.
