Hazard 4 Heavy Water Diver BlackTie B Watch - Silver

Engineered for rugged environments, the Heavy Water Diver BlackTie B watch combines a titanium case with a lightweight design. Featuring water resistance up to 300 metres, tritium illumination, and a high-precision Swiss movement, this model is built to perform reliably in demanding conditions, both on land and beneath the surface.

Powered by a Ronda 515 quartz movement and a Renata 371 battery, the watch case measures 50mm in diameter and is crafted from grade 2 titanium, providing a lightweight, robust, and hypoallergenic construction.

Offering an impressive water resistance of 30 atmospheres, the watch is well-protected during dives up to 300 meters and swimming sessions. A fluted unidirectional diving bezel with a tritium zero marker, combined with a user-friendly screw-down crown, ensures reliable dive time adjustment. The oversized crown facilitates operation even when wearing gloves or underwater.

The dial is accented by prominent, easily legible military-style numerals created using 3D technology. An integrated 24-hour scale allows for straightforward military time reading, while an additional inner ring with minute markers enhances visibility.

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

Overall durability is ensured with sapphire crystal glass featuring an internal anti-reflective layer, improving legibility even in bright sunlight.

The hands, hour markers, and zero indicator feature microtubes filled with tritium gas, delivering continuous, high-intensity luminescence without requiring external activation. Tritium tubes are raised 80% above the dial surface, ensuring optimal readability from multiple viewpoints, not solely from a top-down perspective. Tritium illumination guarantees clear visibility of the watch face, even in complete darkness.

Tritium’s half-life is 12 years, resulting in the brightness decreasing by half over that period.

Exceptional comfort during wear is provided by the titanium bracelet. Highly resistant to the harmful effects of moisture and sweat, the chosen material excels in demanding conditions, making it suitable for a broad range of activities. A special lock on the bracelet ensures protection against unwanted unfastening.
