    Founded in 1989, Luminox built its identity around watches designed for exceptional readability in low-light conditions. In 1992, the brand began working with the U.S. Navy SEALs to develop a watch suited to demanding night missions, leading to the Original Navy SEAL series. That focus on visibility, durability and purpose-built design continues across Luminox collections today
