I haven't wore a watch in over 25 years. I've got nothing in my life that I got to schedule for.

What makes the glow? Is Tritium on the periodic chart or does it come from meteorite or something?

That doesn't make me feel good wearing a radioactive watch.

Tritium is an isotope of hydrogen, which allows it to readily bind to hydroxyl radicals, forming tritiated water (HTO), and to carbon atoms. Since tritium is a low energy beta emitter, it is not dangerous externally (its beta particles are unable to penetrate the skin),^[20] but it can be a radiation hazard when inhaled, ingested via food or water, or absorbed through the skin.^{[21][22][23][24]} HTO has a short biological half-life in the human body of 7 to 14 days, which both reduces the total effects of single-incident ingestion and precludes long-termbioaccumulation of HTO from the environment.^[23][25] Biological half life of tritiated water in human body, which is a measure of body water turn over, varies with season. Studies on biological half life of occupational radiation workers for free water tritium in the coastal region of Karnataka, India show that the biological half life in winter season is twice that of the summer season.^[26]

It is also used in the manufacture of nuclear weapons. Could not figure where this thread was going with that title.

tritium is a beta emitter and the particles dont even penetrate the dead layer of skin. its safe.

 

i figured someone would know what it was beside me lol

the other thing i like is they will glow upwards of 20 years. 

I have a pretty good compass with this.  It is pretty nice, but I can't say I've had to use it much in the dark.
