Very interesting to see this Autavia . . . There has been some discussion of the "Pre-Viceroys", and this seems to be one of them. Your watch has the Viceroy style hands, with numerals 1 through 12 on the hour recorder, but was purchased in March 1971, one year before the start of the Viceroy promotion. Of course, this one has the MH bezel, and the Viceroys had the Tachymeter bezel. But we also saw some "Pre-Viceroys" with the Tachymeter bezel. These are sometimes called the "NT" or "BLT" models, with the "N" or the "BL" identifying the black dial and the "T" identifying the Tachymeter bezel.

I will look through some files and add any other interesting information, in additional postings in this thread.
