Luminox’s Deep Dive has been used for 20 years by the Navy Seal, America’s coast-guards, and by the legendary diver Stan Waterman. The brand’s new version is even more impressive, with water-resistance to 50 bar (500 m/1500 ft). Certified for professional use, it meets the stringent ISO 6425 norms for diving watches. A patent-pending blocking system for the bezel and crown protector, an automatic helium valve, and a case with special water-resistant gaskets are just some of its many characteristics. And if those weren’t enough, there is its unique Luminox Light Technology (LLT) system providing continuous illumination for 25 years thanks to the micro gas tubes that emit a blue glow, the last colour that the human eye is capable of distinguishing at great depths.
