HWD - Blackout

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.

Very happy with this watchReview by Scott
Great product! Best tritium watch I've worn. Good value. (Posted on 7/25/2018)
Great WatchReview by Michael
Great watch, price is a little much for what it is, thought the tritium would have been a little brighter. Love the strap but the N.A.T.O fabric strap is pretty much sh*t for a $900 Watch. Other than that, Watch has a great look and feel (Posted on 3/11/2018)

HiReview by ALEXEY
I like it !!! (Posted on 12/19/2016)
Great looking watchReview by BW
I recently received the heavy water diver as a gift. I am very pleased with the design and looks of the watch. It is large no doubt. But looks good on my 7.25 inch wrist. It wears light despite its size. But not so light it feels cheap.
Only concerns are occasional bumping the bezel with normal use. It seems to spin a bit too easily. Also the date window could be larger. I'm 48. Just heading into the world of reading glasses, and the date is hard to read without pulling my hand away slightly.
Overall I love the watch. (Posted on 9/27/2016)

What I the warranty on the Heavy Water watch? What type of batteries power it and how long are they projected to last? Thanks.

I believe these are the answers you're looking for:

- The standard warranty is 1 year, 2 years with registration of your watch.

- It is powered by a #371 (1.5v) battery

- The battery is estimated to last about 45 months (2-3 years)

Thank you for contacting Hazard 4
