The Luminox XB.3716 is a robust wristwatch for demanding environments, equipped with the brand's signature self-powered illumination system. This ensures continuous visibility in low light conditions without external light sources or battery activation. The model has a durable stainless steel case with a diameter of 45 mm and a one-sided bezel. It is water-resistant to 200 metres (20 ATM) and is suitable for professional maritime activities and water sports. A scratch-resistant sapphire crystal protects the dial with luminous hour markers, hands and a date window at 3 o'clock. Powered by a precise Swiss quartz movement, it offers reliable timekeeping with minimal maintenance. The black polyurethane strap offers comfort and resistance to salt water, UV radiation and extreme temperatures, secured by a stainless steel clasp. The Luminox XB.3716 measures approximately 45 mm in case diameter, 13 mm in thickness and weighs around 85 grammes, providing a balanced feel on the wrist. The tritium gas tubes integrated in the markers and hands emit light for up to 25 years and improve readability in complete darkness. Designed for users who need a reliable watch for outdoor adventures, tactical operations or daily wear in challenging conditions, this model combines functional design with long-term durability. The matt black finish reduces reflections, while the solid case back offers protection against shocks and moisture. As a successor to earlier Luminox diver's watches, it maintains the brand's commitment to quality materials and precise construction, suitable for professional and recreational use.
