Hazard 4 Heavy Water Diver Nightwatch B - Black

The Heavy Water Diver Nightwatch B is a lightweight and durable watch with a titanium watchcase, offering water resistance up to 300 meters. It features tritium backlighting and a precision Swiss movement. It will perform well in harsh 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.

A water resistance of 30 atmospheres protects the watch during diving up to 300 meters and swimming. The unidirectional, fluted diving bezel with tritium zero indicator and screw-down crown allow precise diving time setting. The large size of the crown makes it easy to operate with gloves or underwater.

The watch's dial has large, easy-to-read military-style numerals made with 3D technology. An 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 that indicates the current day of the month.

The watch is protected by a scratch-resistant sapphire glass with an internal anti-reflective coating, which guarantees excellent legibility even in bright sunlight.

The hands, indexes and zero indicator are equipped with tritium microtubes, emitting constant, intense light without activation. The tubes are raised 80% above the surface of the dial for visibility from different angles, guaranteeing legibility in the dark.

Tritium has a half-life of 12 years, meaning its brightness will halve after that time.

The watch features 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 is moisture and sweat resistant, making it an excellent choice for intense activities. A special locking mechanism prevents accidental detachment.

The quick-change strap system with screw-in pins makes it easy to adjust the watch to the user's preference. A Torx 6 screwdriver is required to remove it.
