whatever those "t's" mean.

Those Ts simply refer to the luminous substance used in the watch
to make the hands and dots "glow in the dark". I believe the Ts
stand for Tritium, the amount of Tritium used is above a certain
industry established limit for this slightly radioactive
substance.

Tritium is a radioactive isotope of hydrogen, the one after
deuterium.

Unlikely that thats in a watch to make the hands glow.

Then what substance is in "Tritium tubes" that make
several makes of watches hands glow ????

Those are actually glass vials, and it isnt
really that practical to do the 'dots' that way.


Oh, really? G

You'd be well advised to do a "tiny" bit of research on the
commercial use of Tritium: quite a number of companies use "dots" on
their products, especially in the armaments field.

Beretta, for example. VBG

Irrelevant to dots in watches, stupid.
