HAZARD 4 Heavy Water Diver™ : Titanium Tritium Dive-Watch
Product Overview
The HAZARD 4 Heavy Water Diver™ is a high-performance titanium dive watch engineered for extreme conditions and professional use. Designed with input from special forces and explorers, it combines military-grade durability with precision Swiss movement and self-powered tritium illumination. Built entirely from titanium, it delivers unmatched strength at half the weight of steel watches, making it ideal for divers, tactical professionals, and outdoor adventurers. Its bold, submarine-inspired design transitions seamlessly from underwater missions to formal settings, offering both functionality and refined style. Whether you’re tracking time zones with the GMT model or relying on continuous visibility in total darkness, this watch is built to perform when it matters most.
Key Features
- Self-Powered Tritium Illumination: Equipped with Swiss-made tritium (H3) gas lamps, the watch face and bezel glow continuously without requiring external light exposure—unlike traditional luminescent paints that fade overnight. This ensures instant readability in complete darkness, critical for night operations or deep-sea dives.
- Swiss Movement Accuracy: Powered by a precision Swiss movement, the watch delivers reliable timekeeping with consistent accuracy, meeting the standards required by professional divers and tactical teams.
- 100% Titanium Construction: The full titanium build provides exceptional strength while reducing weight by 50% compared to steel watches. This makes it comfortable for extended wear without sacrificing durability in harsh environments.
- 300M Water Resistance: Engineered as a true dive watch, it withstands depths up to 300 meters (990 feet), meeting ISO standards for saturation diving and underwater exploration.
- 60-Click Uni-Directional Bezel: Features a precision-machined dive bezel with 60 audible clicks for accurate timing during dives. The bezel includes a tritium-filled zero marker for low-light visibility and is designed to prevent accidental rotation.
- Integrated 24-Hour Scale & GMT Function: The GMT models include a daylight ring and an additional hand to track a second time zone—ideal for travelers, pilots, or professionals coordinating across regions.
- 3D Stencil 2-Layer Face Design: The numerals are crafted in a raised, two-layer stencil format with an angled chapter ring, enhancing legibility and adding a tactical yet sophisticated visual depth suitable for both field and formal wear.
- Screw-Down Crown: Ensures water resistance by sealing the crown when tightened, preventing moisture ingress during dives or wet conditions.
- Military-Inspired Aesthetics: Bold, angular design cues drawn from submarine instrumentation give the watch a distinctive presence, while available colorways and strap options allow customization for tactical or urban use.
