Luminox Watch Navy Seals RSC XS.3254.CB. Like many other American success stories, Luminox came from a forward-thinking individual realising a need in the market and meeting it. Luminox’ self-powered illumination (LLT) allows one to view time at-a-glance, no matter what the light level, even in complete darkness – up to 25 years of complete darkness, in fact. Being able to read time effortlessly under any and all circumstances fills a need for various military and law enforcement groups, which is why the U.S. Navy SEAL Procurement officers came to us asking us to create dive watches for them for night missions.
