Sure. Tritium releases very low energy beta particles; even a thin casing will render this safe.

- jjtheblunt 7y agoI could swear that, as a kid near Chicago in the early 1980s, I had a tritium-backlit Timex or Casio digital watch. That said, I can't find it online...and gave it away decades ago.
- dole 7y agoI could be wrong but tritium on watches usually wasn’t typically used on the face itself, but in gas tubes or vials on the hands and hours markers. Ball, Marathon and Luminox are three popular watch brands that use them currently. Evidently radium stopped being used for lume in 1970, and while tritium faces may have been a replacement around that time, tritium as used only has a lifespan between 12-24 years.
- SamReidHughes 7y agoTritium was commonly used in luminescent paint on mainstream watches (Rolex, Omega, et al) until the late 90's/early 2000's.
