Hazard 4 Heavy Water Diver Nightwatch Bracelet - Black

The Heavy Water Diver Nightwatch Bracelet boasts a lightweight yet durable design, featuring a titanium case. Engineered to be water-resistant up to 300 meters, it includes tritium backlighting and relies on a precision Swiss movement. Built to excel in extreme conditions, whether submerged or on dry land.

Titanium watchcase, quartz movement

The watch features a Ronda 515 quartz movement, powered by a Renata 371 battery. The watchcase, measuring 50 mm in diameter, is constructed from grade 2 titanium, making it lightweight, durable, and hypoallergenic.

With a water resistance of 30 atmospheres, this watch is safeguarded during activities like diving up to 300 meters and swimming. The unidirectional, fluted diving bezel with a tritium zero indicator and screw-down crown ensures accurate setting of diving times. The crown's large size facilitates easy handling, even when wearing gloves or underwater.

The dial of the watch features large military-style numerals crafted with 3D technology for ease of reading. An integrated 24-hour scale assists in reading time in military format, and an extra ring with minute markers enhances visibility within the dial.

A dater on the dial displays the current day of the month.

Scratch-resistant sapphire glass with an internal anti-reflective coating protects the watch, ensuring exceptional clarity even in bright sunlight.

Tritium backlighting

Tritium microtubes on the hands, indexes, and zero indicator emit a steady, bright glow without needing activation. The tubes are elevated 80% above the dial's surface, ensuring visibility from various angles and readability in darkness.

Tritium features a half-life of 12 years, so its brightness will be reduced by half after that period.

Durable bracelet

The titanium bracelet provides comfortable wear. Its material withstands harmful effects of moisture and sweat, making it perfect for a variety of activities. A special lock on the bracelet prevents accidental unfastening.
