    Hi,
    is it true that all watches with luminous markings and hands are marked "T" left or / and right
    of the "Swiss Made" at the bottom?
    Thanks for any hints

    No. Radium lume on the earlier models wasn't marked. Nor were tritium watches from before the Swiss directive of 1962/63 I believe.

    So "T" would be for Tritium but not neccessarily on a 1960 watch, right?

    FIFY
    After that tritium on a dial should have at least one T
    Confusingly the T disappears again on some Omegas with tritium mid 70s (ish)
