Luminox NAVY SEAL Diver's Quartz XS.3501.BO.F 200M Men's Watch Luminox puts to use its long watchmaking tradition and creates the Navy Seal Diver, inspired by the intrepid military fiving watches. It is committed to an outstanding performance under any circumstance; on land or in the waters. It’s made from a different kind of carbon composite material – the Carbon ox – which is lighter than titanium and many more times shock and scratch resistant; anti-magnetic and chemically inert. Always visible under all circumstances; it emits light on its own, without depending upon any other energy source.
