## Overview

The Heavy Water Diver Blacktie White GMT is a 50mm titanium dive watch featuring self-powered tritium illumination for unmatched night visibility, Swiss precision movement, and 300M water resistance. Designed for professionals and adventurers, it combines military-grade durability with sophisticated style, including a GMT function for tracking dual time zones. Equipped with scratch-resistant sapphire crystal and a custom T.P.R. band, it’s engineered to perform in extreme environments while making a bold statement on your wrist.

## Description

Hazard 4(R) Heavy Water Diver(R) 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. The GMT models include a daylight ring plus an additional hand for tracking a second time zone.

Review: Not bad - This is a big watch at 50mm, a little too big, 46 or 47mm would suffice for my 7.5" wrist. Because of the ample size it tends to look like a costume watch that didn't cost $750, otherwise it looks good and serves its function well. It still looks ultra utilitarian and that's what I was going for, the numbers are huge and clear and unlike the Breitling you see in the background it is faster to look at your wrist to tell time with the Hazard than glance at your phone. The GMT feature is useful if set to the same timezone so you can tell time in 24hr mode quickly. The watch is very light so you don't notice the hulking disk on your arm at all compared to watches that are 10 times the price. This is a great 2nd or 3rd watch and a good addition to any man-jewelry collection. I think I'll get the titanium bracelet that goes with it, hopefully it has the same bead blasted finish as the case and it makes it look more like what I paid for it. So, if you need a big, burly dive watch in your collection then this is a good one that you won't see others wearing. It's not perfect, but it's pretty good and worth the money so far, and at $750 it's still considered value priced for some crazy reason- I blame Switzerland.
Review: Really cool watch - I really like this watch. It's a bigger watch, fills up the wrist nicely. I even got the black silicone band so I chould have options. It's very well made. It's not a heavy watch. The tritium tube's glow is remarkably easy to read at night. It appears to be very durable but at that price point I'm afraid to be anything but gentle with it.

### ⭐⭐⭐⭐⭐ Awesome Watch.
*by J***Y on December 27, 2023*

So far this watch is amazing. No issues at the time of writing this review (roughly 1mo ownership) 50mm watch face sounded giant, but even on my arm I don’t think it’s as bad as I had thought. I’m not a large built guy so it had me worried. PVD finish is very nice and uniform, we will see how it holds up in a year. The tritium glows bright, zero difficulty seeing the vials. I’m not planning to bang this watch up, so I can’t comment on durability, but it does seem to be built like a tank for what that’s worth. If you can afford it, I’d recommend it. I don’t think you’d be disappointed.
