If you want a watch you can read in the dark, you will run into two technologies: tritium and Super-LumiNova. They both glow, but they work in opposite ways. Here is the honest comparison.
Super-LumiNova
A photoluminescent paint that charges from light, then glows brightly for a short while and fades over a few hours. It is bright right after charging, dim by morning, and free to add to any watch.
Tritium
Sealed gas tubes that glow on their own, with no charging, all night, every night, for years. It is dimmer than a freshly charged lume but constant, which is why it is the choice for tool and dive watches. Full explainer: what a tritium watch is.
Which is better for you?
If you need reliable legibility through the whole night, tritium wins. If you only need a few hours of bright glow, LumiNova is fine. For always-on tritium, see the Luminox collection.

Frequently asked questions
Is tritium brighter than Super-LumiNova?
No. A freshly charged Super-LumiNova is brighter at first, but it fades within hours. Tritium is dimmer but glows constantly for years.
Does tritium need charging?
No. Tritium tubes glow on their own with no light needed, which is the main advantage over photoluminescent lume.
Which is better for a dive or tool watch?
Tritium, because it stays readable all night and underwater without needing to be charged by light first.
