Tritium watches are preferred by most of their users for their luminescence in the dark. These watches make it easier to tell the time without having to look for another light source. A safer replacement for watches with highly lethal radium, tritium watches continue to glow for years without fading. Tritium is actually a radioactive form of hydrogen that is used to fill tubes in watches. But don’t worry – it is entirely safe, as tritium is used in airplane cockpits and gunsights. However, the photoluminescence of tritium does fade over time, albeit at a very slow pace.

If you are looking for a tritium watch to buy for a special someone or for yourself, then look no further! Check out our top pick of the best tritium watches that have an impressive luminescence compared to other glow-in-the-dark watches.
