I was looking at Tag from probably about 1999 or so. The bottom said "Swiss Made" but not "T-Swiss Made -T" so I assume the lume is Luminova or Superluminova. Is this correct? Would Tag have been using non-tritium lume in the late 90's? Did they always put the "T-swiss made-T" on watches with tritium lume?

Im not possitive but I think the T may be required when using tritium.
I've certainly seen a number of Tag's with the "T" but I wasn't sure if it was required or recommended. And I was uncertain at what point in time Tag might have gone over to Luminova/Superluminova (I understand a lot of the swiss manufacturers did).
