Luminox is a Swiss watch brand, and an offshoot of the larger Swiss Concept brand, originating in 1989, which specializes in military and law enforcement-style high-performance watches. Its Swiss-engineered watches are designed to work in extreme conditions that come with Luminox Light Technology (LLT), featuring tritium gas tubes enabling 25 years of constant visibility. Associations with the U.S. Navy SEALs and Lockheed Martin crown some collections, such as Navy SEAL and Recon, which evolve Luminox into a preferred reference of reliability and accuracy in tactical operations.
