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.
