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

The Heavy Water Diver Cavern B watch is a light and durable watch with a titanium case and water resistance up to 300 metres. It is equipped with tritium backlighting and a precise Swiss movement. It is suitable for use in difficult conditions, both underwater and on land.

The watch is equipped with a Ronda 515 quartz movement powered by a Renata 371 battery. The 50 mm diameter case is made of grade 2 titanium, making the whole watch lightweight, durable and hypoallergenic.

Water resistance of 30 atmospheres protects the watch during diving up to 300 m and swimming. A unidirectional, notched diving bezel with a tritium zero indicator and a screw-down crown allow for precise setting of dive time. The large crown size makes it easy to operate with gloves on or underwater.

The watch face has large, easy-to-read military-style numerals made with 3D technology. The integrated 24-hour scale allows for easy reading of time in military format. Inside the dial is an additional minute ring for improved visibility.

The dial has a date display that shows the current day of the month.

The watch is protected by scratch-resistant sapphire crystal with an internal anti-reflective coating, which guarantees excellent readability even in direct sunlight.

The watch is equipped with a GMT function, which allows you to monitor the time in two time zones simultaneously. This is achieved by means of an additional GMT hand, operating on a 24-hour cycle and working together with the 24h scale placed on the dial.

The dial features:

• standard hands (hour and minute) - indicating local time
• a slim GMT hand (with an additional marking) - responsible for the second time zone
• a 24h scale (1–24) at the edge of the dial - enabling GMT time reading

This solution makes it possible to track local time and the time in another region of the world at the same time, without the need to interfere with the main hands' settings. This function is particularly useful when travelling, working in an international environment, and keeping in touch with people staying in different time zones, ensuring clear and quick reading of two independent time indications.

The hands, indexes and zero indicator are equipped with tritium microtubes, which emit a constant, intense blue light without requiring activation. The tubes are raised 80% above the surface of the dial, ensuring visibility from different angles and guaranteeing readability in the dark.

Tritium has a half-life of 12 years, which means that its luminosity will be halved after this time.

The watch has a durable rubber strap with a grooved texture with a map motif and numerous holes that wick away moisture, improve ventilation and prevent sweat from building up on the wrist. The material is resistant to moisture and sweat, making it an excellent choice for intense activities. A special lock prevents accidental unfastening.

The quick strap change system with screw-in pins allows you to easily adjust the watch to your preferences. A Torx 6 screwdriver is required for disassembly.
