: Hi all,

: please have a look at this Heuer chronograph which I have
: purchased. It's a 37 mm chronograph from around 1960-1962. Is it
: the black chronograph 3336 which we find in the Heuer catalog
: from 1962 which also features the 3646 and 2446 Autavia for the
: first time? The only difference I can notice is that the one on
: the added photo which I bought has a tachymeter scale. Any other
: worries about the authenticity maybe? Your input is much
: appreciated. I have a photo of the internals. It's clearly a
: Valjoux allright.

: Could we call this type the pre-Carrera maybe, the same way Rolex
: boasts with its pre-Daytona model?

: As a big fan and owner of Valjoux 72, Valjoux 92 and Landeron
: Carrera's I also fell in love with this one the moment I saw it.
: "It simply had to be part of the Carrera
: collection".Also notice the round pushers, another sign of
: the Carrera about to emerge in '64? The fact that it measures 37
: mm excl. crown makes it a fairly big watch for the early
: sixties, doesn't it?

: Thanks for the input !

: Cheers
: Ron
