I know some of you folks make really cool jewelry - I put a Traser
watch up for auction on e-bay - the watch doesn't work (of course you
could fix it, it has a standard movement), but another cool use would
be to disassemble it and collect the small glass vials that are filled
with tritum and lined with a phosphor - they glow pretty brightly (you
can read by the light from the watch if you are fully dark adapted) and
so they ought to be useful in a jewelry application of some kind -
there are 16 total tubes in the watch (one for each hour positoin, one
on each hand, and one more on the rotating dial).

You should know that the Tritium decays fairly quickly. In a couple of
years, the loss of brightness will be quite noticable. I have a 15 year
old or so watch and the capsules are totally dark even after sitting in
total darkness for a half hour or more.

I had a set of Tritium night sights installed on a handgun about 15yrs
ago, when I was playing deputy. They are totally dead now..went west
about 8-10 yrs after installation, with noticable fading after 5 yrs
