The Luminox Navy SEAL 3500 Series XS.3507 is a Swiss-made men's quartz dive watch built to the demanding performance standards of U.S. Navy SEAL operators. The 45mm round case is crafted from CARBONOX, Luminox's proprietary carbon composite material that is lighter and stronger than stainless steel, with a case thickness of 14mm. A white analog dial features a 12/24-hour display and a date window at the 3 o'clock position, protected by a mineral crystal. The watch is secured with a black polyurethane rubber strap and a buckle clasp.

Luminox Light Technology (LLT) powers self-contained tritium gas tubes embedded in the hands and hour markers, delivering constant illumination in complete darkness for up to 25 years without requiring any battery or external light source. A unidirectional rotating bezel enables elapsed dive-time tracking, while a double security gasket crown and screwed case back maintain water resistance rated to 200 meters (660 feet). The watch ships in Luminox branded packaging with all product documentation.
