Hazard 4 Heavy Water Diver BlackTie B Watch - Black/Silver

Heavy Water Diver BlackTie B watch is a rugged, lightweight model with a titanium case, offering water resistance to 300 metres, tritium backlighting and a precision Swiss movement. It is designed for use 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 50mm-diameter case is made from grade 2 titanium, making the overall design 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 m 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 face 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 face, there is an additional ring with minute markers to improve visibility.

The face features a date display 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 indicator have been fitted with tritium gas-filled microtubes that provide constant illumination at a strong intensity, without the need for activation. The tritium tubes are elevated 80% above the surface of the watch face, making them visible from various angles and not just directly from above. Tritium backlighting ensures that the watch is always visible even in total darkness.

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

The watch features a durable rubber strap that 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 prevents accidental removal.
 

The quick-change system of the strap with screw-in pins allows the watch to be easily adapted to the individual needs of the wearer. A Torx 6 screwdriver is required to remove it.
