The Luminox Navy SEAL ANU 4200 Series (model XS.4221.NV.F) is a Swiss-made 45mm men's quartz watch with a gun metal PVD-coated stainless steel case and a black polyurethane rubber strap. Designed in collaboration with the U.S. Navy SEALs, it is built to serve as reliable first-line tactical gear in the most demanding conditions.

Key features include a Swiss quartz movement, sapphire crystal glass with anti-reflective coating, and a unidirectional rotating black bezel. The black dial displays Arabic numerals with a date function at the 3 o'clock position. The watch is equipped with Luminox Light Technology (LLT) — self-powered tritium gas illumination tubes on the hands and dial ring that glow continuously for up to 25 years without any external light source or battery charging.

The screw-down crown and solid caseback deliver water resistance to 200 meters (660 feet / 20 ATM), making this watch suitable for serious diving and water activities. The rubber strap is 23mm wide and fits wrists up to 8.5 inches. Made in Switzerland.
