Hazard 4 Heavy Water Diver - Nightwatch White, GMT, Green/ Yellow
Description
Hazard 4® watch hands & indicators glow continuously (night or day,) powered by an unusual, government-regulated technology that combines hydrogen-3 gas (tritium/H3), glass tubes, and phosphors into self-contained mini-lamps (expertly Swiss-made in many colors.) Tritium bulbs don't charge by battery, sun, or flashlight, unlike other watches using simple luminescent paint or battery-run film. They don't fade overnight like those paints, and require no button pushing, or battery to exhaust. They are also feather-light. Tritium lights are usually used only for critical applications like military compasses, and night-sights; we nevertheless source them, since our watches are used by those for whom timing can determine survival/success or catastrophe.
The GMT models include a daylight ring plus an additional hand for tracking a second time zone.
Features:
- High water resistance feature set; depth rating of 300 m.
- Ronda 515 Quartz (battery powered); standard battery life on our watches is about 2-2.5 years from the day it is installed.
- Self-contained everglow tritium-vial lamps (tritium has a half-life of 12 years, meaning that in 12 years, it will be half as bright as it is now).
