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

Heavy Water Diver BlackTie B is a lightweight and durable watch with a titanium case, offering water resistance up to 300 metres. 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 50mm-diameter case is made from grade 2 titanium, making the overall design lightweight, durable and hypoallergenic.

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

The watch face has large, easy-to-read 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 is equipped with a date display 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 micro-tubes, emitting constant, intense light without the need for activation. The tubes are raised 80% above the surface of the face to ensure visibility from different angles, guaranteeing legibility in the dark.

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

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

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