Hazard 4 Heavy Water Diver Blackout A Watch - Black

Heavy Water Diver Blackout A watch features a robust, lightweight titanium case, delivering water resistance up to 300 metres, tritium illumination, and a high-precision Swiss movement. Engineered for reliability in extreme environments, the model excels both underwater and on land.

Titanium watch case, quartz movement

Outfitted with a Ronda 515 quartz movement and powered by a Renata 371 battery, the watch features a substantial 50mm case crafted from grade 2 titanium. This construction ensures the timepiece remains lightweight, robust, and hypoallergenic for optimal durability and comfort.

Offering a high water resistance level of 30 atmospheres, the model guarantees reliable performance during dives up to 300m and while swimming. The notched unidirectional diving bezel equipped with a tritium zero marker, together with the easily maneuvered screw-down crown, enables accurate measurement of dive time. The oversized crown enhances usability, especially when wearing gloves or operating underwater.

The dial stands out due to prominent, legible military-style numerals produced using 3D technology. A built-in 24-hour scale supports straightforward reading in military time. An additional inner ring with minute indices boosts legibility on the dial.

A date window on the face conveniently displays the current day of the month.

Protection is provided by a scratch-resistant sapphire crystal with internal anti-reflective coating, which ensures excellent readability in bright lighting conditions.

Tritium backlight

Hands, indices, and the zero marker are equipped with tritium gas-filled microtubes that deliver continuous, high-intensity illumination without requiring any external activation. Positioned 80% above the watch dial, these tritium tubes guarantee visibility from multiple viewing angles, not just from directly overhead. Tritium backlighting guarantees the watch remains readable even in complete darkness.

Tritium possesses a half-life of 12 years, indicating that after this period, its brightness will be reduced by half compared to its current level.

Sturdy strap

Equipped with a robust rubber strap, the watch incorporates a grooved texture displaying a map motif along with multiple moisture-wicking holes to enhance airflow and minimize sweat accumulation on the wrist. Crafted from materials resistant to the harmful effects of both sweat and moisture, the strap offers excellent suitability for demanding activities. A dedicated lock positioned on the strap ensures protection against unintended detachment.

The strap's rapid-release system featuring screw-in pins allows for effortless personalization and adjustment to the wearer’s preferences. Removal requires a Torx 6 screwdriver.

    A powerful watch, perfect for a man's hand. I got it from a friend to test and I am impressed—big, black, my favorite color. I have a large hand and a thick wrist, so that's why I liked it so much.

    Beautiful men's watch, massive and heavy - one with character. It makes an amazing impression in person, has everything you need, and the luminous effect in the dark is stunning, it's awesome. It's not cheap but definitely adequate for its durability and quality.
