ArmourLite watches have tiny glass tubes that are filled with tritium gas and then hermetically sealed. The electrons of the gas continuously react with phosphorescent paint resulting in a radio luminescent light source that glows constantly for up to 25 years. No external power source or charging-by-light is necessary to maintain the glow. The glow is completely self-powered.
The watch is protected by shatterproof Armourglass crystal that can withstand up to 6,000 Vickers, whereas most watch crystals can only withstand about 700. Using the same technology as bulletproof glass, we have achieved a crystal that won’t shatter even when one layer is compromised.
The watch features an ultra tough and corrosion resistant 316L stainless steel case with a diameter of 47mm. The double-gasket screw-in crown on the right side of the case is protected by two side shields. Plus, 2 heavy-duty screw bars keep the band firmly in place during strenuous activities
