: Very unusual, it most likely incorrect, however I have seen this
: type of Valjoux 72 with some brass parts before, so it is not
: 100% out of the question, but we would need to know more
: What is the code on the bottom left hand side of the base plate?
: There should be R for Valjoux and 72 for the movement on the
: right side and then normally MN on the left. It is normally MN
: on Valjoux 72 (1st execution Ed Heuer Autavia 2446 and the very
: earliest Ed Heuer Carrera 2447 are the exception whereby there
: is no two letter code).
: However I have now seen two original Carrera 2447 with AR on the
: base plate with brass Heuer Leonidas bridges which have the
: words "Seventeen 17 Jewels Unadjusted, Swiss" also on
: the bridge, instead of on the left hand side of the plate. (AR
: is the code for Enicar). Yours has no "17 Jewels" info
: I am told that the some watchmakers constructed watches for both
: companies. It was a cottage industry back then, some Enicar were
: even constructed at Heuer in Switzerland and also in busy times
: much work was done "overtime" at watchmakers houses
: also including their relatives also.
Thanks again for your lengthy explanation. Very informative. I have done some quick further research and indeed, there are brass V72 movements, some fitted to Enicar Sherpas as you pointed out. So based on your explanation, these could have very well have been fitted to Heuer units, including Carreras and Autavias. Will continue with the research and hopefully get those scans today.
In addition, it has been mentioned that this could be a 726, the revised version of the 72 but in close examination, still think it is a 72.
Thanks again for the help.
