Tritium is a radioactive isotope, and like other lumes it has a finite lifespan.
Non-radioactive lumes are used in watches. They're less bright than radioactive lumes, and have branded names. Super Luminova is a popular one.
Besides, at my age, if a woman gave me the time of day it'd be like a dog chasing a car - wouldn't know what to do with it if I caught it.

Tritium has a half life of 12.3 years. Half of it may be gone by then but half still remains. 24.6 years down the road a quarter of what you started with remains but it’s still not gone. Thousands of years down the road the amount that remains may be vanishingly small but some will still remain. When you’re down to one atom, it’s impossible to know when it will decay leaving behind an atom of He3.Tritium is a radioactive isotope, and like other lumes it has a finite lifespan.

Back in the 60s and 70s Seiko was fighting hard to be considered a time piece manufacture of the highest quality. The Swiss and the French were working hard to exclude them from the club. Seiko built some great watches in that period. There are some good accounts of this battle on the interwebs.
Went out to dinner in NYC last night and wore this one.

I haven’t worn it in a while. I don’t think I changed the date.
Why? Are you kind of a snob?

Band name alert: Half Life
I have a simple SEIKO , metal, but the advantage is it's solar powered. Even a lamp charges it. So no need for batteries- ever.
That's clever, not snobbery.
Yes, I understand radioactive decay. After a couple of half life cycles a tritium tube will also have only a quarter the luminescence it started out with.

Which was my point.
Radium has a much longer half life - ~1500 years. My grandfather's pocket watch, which is over a century old, still glows very nicely in the dark thanks to its radium lume.
Some quartz watches have batteries that last ten years. Mechanical watches require servicing more often than that.
After 11 pages of submissions, I think it's OK to say, that we are a community who appreciate Seiko watches. Here's mine.
