"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. Sort of like a "warning label". Ts
are used on other watch, also.
