Hazard 4 Heavy Water Diver Nightwatch B - Black

The Heavy Water Diver Nightwatch B is a durable and lightweight watch with a titanium envelope, providing water resistance to a depth of 300 meters. Equipped with tritium backlighting and a precision Swiss movement, it is ideal for extreme conditions, both underwater and on land.

The watch is equipped with a Ronda 515 quartz movement powered by a Renata 371 battery. The 50 mm-diameter watchcase is made of grade 2 titanium, which makes the whole thing lightweight, durable and hypoallergenic.

The model features a high water resistance rating of 30 atmospheres, which effectively protects the watch when diving to a depth of 300 meters or swimming. The fluted unidirectional diving bezel with tritium zero indicator and easy-to-turn screw-down crown allows for precise diving time setting. The large size of the crown makes it much easier to operate with gloves or underwater.

The watch's dial is distinguished by large, clear military-style numerals made with 3D technology. The integrated 24-hour scale makes it easy to read the time in military format. Inside the dial, there is an additional ring with minute markers to improve visibility.

The dial features a dater indicating the current day of the month.

The whole is protected by a scratch-resistant sapphire glass with an internal anti-reflective coating, which makes it easier to read the time on a sunny day.

The hands, indexes and zero pointer are equipped with tritium gas-filled microtubes, which provide constant illumination of strong intensity without activation. The tritium tubes are elevated 80% above the surface of the dial, making them visible from various angles, not just directly from above. Tritium backlighting ensures the watch's constant visibility even in total darkness.

Tritium has a half-life of 12 years, which means that in 12 years it will shine half as brightly as it does today.

The watch is equipped with a durable rubber strap, which features a grooved texture with a map motif and numerous moisture-wicking holes to improve ventilation and prevent sweat from accumulating on the wrist. The material used is resistant to the damaging effects of moisture and sweat, making it ideal for a variety of activities. A special lock located on the strap protects against accidental detachment.

The quick-change system of the strap with screw-in pins makes it easy to customize the watch. A Torx 6 screwdriver is required to remove it.
