For over 20 years, Luminox has partnered with the world's toughest maritime commandos to continuously hone and refine a watch tough enough and useful enough to be considered first line gear for the finest warriors. In World War II, during the era of Frogmen and beach landings under fire, if a piece of diving gear wasn't on the ANU (Authorized for Navy Use) list, you didn't use it. The ANU list of equipment provided these Frogmen of the past and the Navy SEALs of today with a sense of security that their gear would work when needed. It is with this same intent that we name these newly developed watches, the ANU series. If you have an essential mission then use authorized essential gear, ANU by Luminox.
