Reply to comment by MortalPhantom in Why not use hydrogen and deuterium in fusion reaction rather than tritium and deuterium? by Curious_user4445

Before tritium paint they used radium to get the phosphor to glow. The problem is that radium is highly toxic and carcinogenic.

That I had heard the horror stories of. It just didnt seem to make sense to me to use a super-limited resource like tritium for watches and thought titanium would be a more likely candidate for a mid-level, rugged watch.

Tritium is only used for making the hands and face of the watch glow in the dark, titanium would be used for something like the body of the watch.
