So formidable, so reliable, the Luminox® ANU 4221.NV.F Watch is built to specs that make it first-line gear for elite maritime commandos. Authorized for Navy Use, this premium timepiece features stainless steel that's Physical Vapor Deposition coated for massive durability. Multi-jewel Swiss quartz movement and construction renowned for its accuracy. And Luminox self-powered illumination that's there for you both day and night.
Luminox Light Technology (LLT) is always visible
No charging. No button-pushing. No cheap fluorescent paint. The self-powered illumination is made possible with micro gas light sources. The glowing tritium gas is surrounded by a phosphorescent powder layer and then housed in heat-resistant glass. Each light is carefully placed on the hands and dial. And the constant glow each emits is always visible…for up to 25 years.
