The Luminox Navy Seal Dive Watch (model XS.3501.F) is a 45mm Swiss-made dive watch built for divers, special operations personnel, and anyone who needs readable timekeeping in low light and underwater. Luminox developed this line with Navy dive teams in mind, and the priorities show: a lightweight carbon-composite case, a 200-meter water resistance rating, and self-powered tritium illumination that glows without batteries or a charge. It's a working tool first and a daily wearer second, sized and weighted for hard use without feeling like a brick on the wrist. For other field timepieces, see our mil-spec watch options.
The case uses Luminox's carbon-composite material, keeping total weight to roughly 71 grams while staying tough enough for repeated submersion. Inside is a Swiss quartz movement (the Ronda 515 caliber) rated for about a 50-month battery life, paired with time and date functions. The illumination comes from Luminox Light Technology, which uses self-powered tritium micro tubes for a constant glow up to 25 years, so the dial stays legible in zero ambient light with no button to press. A unidirectional rotating dive bezel tracks elapsed time underwater, a screw-down protected crown keeps water out, and a hardened mineral crystal (550 to 650 Vickers) resists scratching. The 316L stainless steel screw-on caseback and 24mm nitrile rubber strap round out the build. Water resistance is rated to 200 meters (660 feet), individually tested.
This watch earns its keep on dives, on the range, and on any job where you read the time in the dark and can't fuss with backlights. The self-powered glow means it works on the first day and the last day of a multi-day operation the same way. The nitrile strap shrugs off salt water and sweat, and the screw-down crown holds its seal through repeated pressure changes. Luminox backs it with a 2-year limited warranty and a 10-year warranty on the tritium tubes. Pair it with a set of tactical sunglasses or browse our other field accessories to round out your kit.
The XS.3501.F is rated to 200 meters (660 feet) of water resistance, and each watch is individually tested. That rating covers recreational and professional diving as well as everyday water exposure like swimming and washing.
No. It uses Luminox Light Technology with self-powered tritium micro tubes that glow on their own, with no charging from sunlight or a backlight button. The glow stays constant in total darkness and lasts up to 25 years per manufacturer specifications.
It runs a Swiss quartz movement, the Ronda 515 caliber, with a battery life of approximately 50 months. That gives you years of accurate timekeeping between service intervals, which is why quartz is common on working dive watches.
Roughly 71 grams. The carbon-composite case keeps weight low compared to all-steel dive watches of the same size, so the 45mm case wears comfortably during long days and active use.
Luminox provides a 2-year limited warranty on the watch and a separate 10-year warranty covering the tritium illumination tubes. Keep your proof of purchase to support any warranty claim.
