There are a number of brands that have really made the use of Tritium tubes their USP. Luminox and Traser spring to mind. With both of these companies, they began with, and still have at their core, a range of black military-style watches. They're great - I have a Luminox 3000 series watch that I still wear regularly, but they're the style of best replica watches that comes up first when you Google GTLS. We are including both on this list, but we're also going to make an effort to show you some of the watches that use GTLS in other styles. Watches that provide that supreme illumination but without the military aesthetics.
