Hazard 4 Heavy Water Diver Arid B Watch - Black

Engineered for demanding environments, the Heavy Water Diver Arid watch features a titanium case for durability and reduced weight, and provides water resistance up to 300 metres. Outfitted with tritium backlighting for superior visibility and powered by a precision Swiss movement, the watch is ideally suited for extreme conditions, whether underwater or on land.

Driven by a Ronda 515 quartz movement and powered by a Renata 371 battery, the watch features a case crafted from grade 2 titanium with a diameter of 50mm. This construction ensures an exceptionally lightweight, robust, and hypoallergenic build.

A water resistance of 30 atmospheres safeguards the watch during dives up to 300 m and swimming. Precise dive timing is facilitated by the fluted unidirectional diving bezel with a tritium zero marker and an easy-to-grip screw-down crown. The oversized crown is specifically designed for comfortable operation with gloves or under water.

A dial with prominent, highly legible military-style numerals—crafted using 3D technology—distinguishes the watch face. The integrated 24-hour scale provides instant access to military time, while an extra inner ring featuring minute indices enhances readability.

A date window on the dial conveniently displays the current day of the month.

Superior clarity is ensured by a scratch-resistant sapphire crystal with an internal anti-reflective coating, enhancing legibility even in bright sunlight.

Equipped with tritium gas-filled microtubes, the hands, indexes, and zero indicator deliver continuous, intense illumination, requiring no manual activation. The tritium tubes are raised 80% above the dial surface, enhancing readability from multiple angles, not solely from a direct overhead view. Tritium backlighting guarantees optimal visibility of the watch, even in complete darkness.

Tritium features a 12-year half-life, ensuring that after 12 years, brightness will remain at half of its original intensity.

A robust rubber strap with a grooved texture featuring a map design and multiple moisture-wicking holes ensures optimal ventilation, effectively reducing sweat build-up on the wrist. The strap is constructed from materials that withstand the harmful effects of both moisture and sweat, making it exceptionally suitable for various demanding activities. A special locking mechanism on the strap secures it firmly in place to prevent unintentional detachment.

The strap incorporates a quick-release system with screw-in pins, allowing effortless customization to suit the wearer’s preferences. Detachment requires a Torx 6 screwdriver.
