Hazard 4 Heavy Water Diver Cavern B GMT Watch - Black/Green

Engineered for challenging environments, the Heavy Water Diver Cavern B watch features a titanium case that is both durable and lightweight. Offering water resistance up to 300 meters, tritium backlighting for enhanced readability, and a high-precision Swiss movement, this model performs reliably in demanding situations whether underwater or on land.

Fitted with a Ronda 515 quartz movement and powered by a Renata 371 battery, the watch ensures reliable timekeeping. The 50 mm case, crafted from grade 2 titanium, ensures the entire watch is lightweight, robust, and hypoallergenic.

Offering exceptional durability, the model boasts a high water resistance rating of 30 atmospheres, providing effective protection during dives up to 300 meters deep or swimming. The notched, unidirectional diver’s bezel with a tritium zero marker and an easily operated screw-down crown guarantee precise dive time adjustments. The oversized crown enhances usability, even when wearing gloves or operating underwater.

Featuring a dial with prominent, easy-to-read military-style numerals manufactured in 3D, the watch face ensures excellent legibility. An integrated 24-hour scale facilitates quick reading of military time, while an additional inner ring displaying minute indices further improves visibility.

A date display on the dial conveniently indicates the current day of the month.

Comprehensive protection for the watch is provided by a scratch-resistant sapphire crystal with an internal anti-reflective coating, enabling effortless time reading even in bright sunlight.

The GMT variant includes an additional scale that allows tracking of time across different time zones.

Hands, indices, and the zero marker come equipped with tritium gas-filled microtubes that deliver continuous, high-intensity illumination without the need for activation. The tritium elements are elevated by 80% above the dial surface, enhancing visibility from multiple angles, not solely from a top-down perspective. Blue tritium backlighting guarantees optimal legibility of the watch face, even in total darkness.

Tritium possesses a half-life of 12 years, meaning its brightness will be reduced by half after a 12-year period.

A robust rubber strap featuring a grooved texture, a map-inspired motif, and multiple perforations efficiently channels away moisture, boosts airflow, and reduces sweat accumulation on the wrist. Crafted from materials engineered to withstand both moisture and perspiration, the strap excels in demanding environments. A dedicated locking mechanism ensures secure fastening, guarding against accidental release.

The rapid strap replacement system, equipped with screw-in pins, allows for seamless adaptation of the timepiece to the wearer’s requirements. For strap removal, a Torx 6 screwdriver is necessary.
