Approximately 80 MBq (2 mCi) of tritium are used in each wristwatch, and approximately 20 MBq (0.5 mCi) are used in each pocketwatch or clock, according to NRC li- censing files.

How long does tritium last in a watch?

The GTLSs used in watches give off a small amount of light: Not enough to be seen in daylight, but visible in the dark from a distance of several meters. The average such GTLS has a useful life of 10–20 years.
