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

Heavy Water Diver BlackTie A wristwatch engineered for durability and lightness, featuring a titanium case, water resistance rated up to 300 meters, tritium backlighting, and a high-precision Swiss movement. Built for extreme environments, both beneath the surface and on land. Distinguished by blue tritium illumination.

Powered by a Ronda 515 quartz movement and a Renata 371 battery, the watch features a 50 mm case crafted from grade 2 titanium. This construction ensures that the entire piece remains lightweight, as well as durable and hypoallergenic.

Offering a substantial water resistance rating of 30 atmospheres, the watch is safeguarded during dives of up to 300 meters and swimming sessions. The notched, unidirectional diving bezel with a tritium zero marker and an easily handled screw-down crown provides accurate dive time adjustment. An oversized crown is designed for convenient use with gloves or while underwater.

The dial is marked by bold, legible 3D numerals in a military style. An integrated 24-hour scale delivers quick reference for military time, while an internal minute track enhances legibility.

A date display indicates the current date of the month.

Protection for the entire watch is provided by a scratch-resistant sapphire crystal with an internal anti-reflective coating, greatly improving visibility in bright sunlight.

Equipped with gas-filled tritium microtubes, the hands, indices, and zero marker deliver continuous, high-intensity illumination without the need for external activation. Tritium lights are elevated 80% above the dial’s surface, ensuring visibility from multiple angles, rather than just a direct overhead view. The blue tritium backlight guarantees clear readability of the watch face even in absolute darkness.

Tritium features a half-life of 12 years, meaning after 12 years, its luminosity will be reduced to half of its original brightness.

Outfitted with a robust rubber strap featuring a grooved texture adorned with a map design and multiple perforations, the watch ensures efficient moisture drainage, improved airflow, and prevents sweat accumulation on the wrist. The strap material is highly resistant to both moisture and perspiration, making it perfectly suited for a variety of demanding activities. A special locking mechanism on the strap secures it in place, effectively eliminating accidental release.

Thanks to a rapid strap replacement mechanism utilizing screw-in pins, the watch can be quickly customized to suit individual preferences. A Torx 6 screwdriver is necessary for the removal process.
