Hazard 4 Heavy Water Diver Nightwatch GMT Watch - Black
The Heavy Water Diver Nightwatch B model is a robust yet lightweight watch with a watchcase made of titanium, guaranteeing water resistance of 300 meters. Thanks to its tritium backlight and precise Swiss mechanism, it will perform well in extreme conditions, both underwater and on the surface.
Titanium watchcase, quartz movement
The watch uses a quartz mechanism Ronda 515, powered by a Renata 371 battery. The watchcase with a diameter of 50 mm, made of titanium class 2, provides lightness, durability and hypoallergenic properties.
Water resistance of 30 atmospheres effectively protects the watch during diving to a depth of 300 meters and swimming. The unidirectional, fluted diving bezel features a tritium zero indicator, and the large screw-down crown allows easy operation - even with gloves or underwater.
The dial is distinguished by large, clear military-style numerals made with 3D technology. An integrated 24-hour scale makes it easy to read the time in military format, and an additional ring with minute markers improves legibility.
The watch is equipped with a date pad, which indicates the current day of the month.
It is protected from scratches by a sapphire glass with an internal anti-reflective coating, improving visibility even in intense light.
The GMT version has an additional graduation to keep track of time in different time zones.
Tritium backlighting
The hands, indexes and zero indicator are equipped with microtubes filled with tritium gas, which guarantee intense, constant illumination without the need for activation. The tritium tubes are elevated 80% above the surface of the dial, which increases their visibility from different angles, not just from above. As a result, tritium illumination provides excellent readability even in total darkness.
Tritium has a half-life of 12 years, which means that after this time the brightness of the backlight will decrease by half.
Durable strap
The durable rubber strap is distinguished by a grooved texture with a map motif and numerous holes that effectively wick away moisture, improve ventilation and prevent sweat from accumulating on the wrist. The material used is resistant to moisture and sweat, making it suitable for intense activities. A special locking mechanism prevents accidental unfastening of the strap.
The quick-change strap system, based on screw-in pins, allows the watch to be easily adjusted to the user's preferences. A Torx 6 screwdriver is required to remove it.
