Luminox Technology. Always Visible

Luminox watches undergo additional manufacturing steps that other watches do not require. The Luminox self-powered illumination system must be installed into each and every watch in a costly and time-consuming process. But it is what makes Luminox watches special. Tiny self-powered micro gas lights developed by the world leader in the luminous compound industry are installed into the hands, hour markers, and when necessary, even the bezels of Luminox watches. Luminox watches need no external light source to “charge” the paint on the dial or hands, as do conventional luminous watches. Nor do they require the push of a button to light the dial as do watches with electroluminescence. The U.S. military has long recognized the advantages of micro gas light sources…and their use is specified in procurement specification MIL-W-46374F.

Self-powered illumination–Luminox Light Technology (LLT) provides time-at-a-glance, at any time. No matter what the light level, even in complete darkness—up to 25 years of complete darkness, in fact. It is why the U.S. Navy SEALs Procurement officers first came to Luminox requesting the development of special dive watches for night missions. It why U.S. Air Force pilots flying the F-117 Nighthawk™ Stealth Jets asked Luminox to develop timepieces for their special purposes. And it’s why various military and law enforcement groups, and so many other groups of “heroes”, truly understand and appreciate the inherent benefit of wearing a Luminox Watch. Ask one for the time. Any time.
