: Thank you again for your valuable insight. Would it be possible for

: thanks again.

My two cents adding to the great discussion here, my guess is this watch given the relatively early serial number (69'XXX) was originally born with a silver or white dial and that it went back for service at Heuer Time Corporation (HTC) in NYC and at that point the customer was given the option of a new dial. Over the years, I have seen a few watches that went through service at HTC and had a variety of things done to them that probably would not have been done in Switzerland, changes in dials and hands, etc. for customers. My sense is that the Swiss would have been a bit more OCD and not put an Autavia dial in a Carrera case, but that HTC had a variety of odd components sent to them from Switzerland for various watches. Perhaps the owner saw a Carrera 2447NST in a store window or advertisement and asked if he could get something similar, and they had this Autavia dial that was the closest option. But I have extremely strong doubts that this watch left the factory in Switzerland in this configuration.
