Reference number gets truncated on the case, e.g., the below would be 143.1.60 for yellow gold. 143.2.60 would be the same in pink gold. Mine says 140.8.89 for a 140.840.892.
I'm still trying to figure out exactly when "T SWISS MADE T" appeared on the Master dials. Mine has it from '99 or so. Earlier tritium dials do not, as with the
@pcdubc example above.
You have a point on the alignment.
