I’m trying to understand the difference between “T Swiss T” and “T Swiss Made T” on Pie-Pan Datejust dials.
I have been told that “T Swiss Made T” dials on 16XX Datejusts are all later service dials but have a hard time believing that as I have seen quite a few with considerable age and completely dead Tritium. I do notice that they have text reminiscent of the newer dials with more pronounced and larger fonts especially on the words Rolex and Datejust.
Is it possible that they were the last version of Pie-Pan dials or possibly made by a certain manufacturer or for certain markets? Or is my friend correct and all “T Swiss Made T” dials are service? If this is the case approximately what years were they made? Could all the age I’ve seen on some examples be from the 80s or 90s forward? Some early 16XXX dials have only “ T Swiss T” while some (later?) ones have “T Swiss Made T”. Is this a hint to the age of the Pie-Pan dials that share the same wording?
Someone please enlighten me if you can.
These three “T Swiss Made T” dials have totally dead lume and as you can see one is even tropical:
This later Pie-Pan “T Swiss T” dial shares similar large fonts on the words Rolex and Datejust.
