Thank you for your answer...
With "number" I mean the approximate quantity of watches produced. The fact is that it is very difficult to find any type of early Carrera on the internet, but it's extremely difficult to find a three register Carrera with valjoux 72.
I recently buy a Carrera 12 ref. 2447N (Black Dial) and I have very little points of reference......

: The Carrera with Valjoux 72 was introduced in
: 1964 . . . I would estimate that they used
: the Valjoux 72 through the 1960's, and
: switched to the 77XX movements around 1970.

: I am not certain of what you are asking about
: the "numbers". I am not aware of
: any records that track the serial numbers.
: In terms of the number of watches that were
: produced, I have never seen this
: information.

: Thanks for the question.
