When you need a timepiece built for the long haul, you need Luminox. Luminox came from a need to have an easy to read watch face, day or night. By developing a proprietary technology using enclosed gas cartridges, Luminox created constant illumination to the hand and dial. Unlike luminescent paints that quickly run out, the gas cartridges built into Luminox watches are always lit, for an incredible 25 years. This has made Luminox the number one choice for adventurers and military professionals who need a dependable timepiece that just works perfectly, all the time. This Sea Turtle model is put together with a pure rubber strap and high quality fixtures to make an extremely robust timepiece. It’ll shrug off knocks and scrapes, it’ll look excellent on your wrist casually and in demanding environments, and above all, it will show you the time accurately, all the time.
