: Possibly. There should always be a serial number on a 2447 case.

: There's quite a lot of info on OnTheDash, including pictures and
: the chronograph table. It's a good place to start. Richard
: Crosthwaite and Paul Gavin have produced a book on the Carrera,
: check it out.

: Umm, they do have serials? If you mean the model reference, that is
: also engraved on later first generation watches.
Thanks for the reply, Mark.
I didn't know that the Crosthwaite/Gavin book was out yet, I'll definetely check it out.
My comment about the serial numbers is about the fact that, apart from the case number (which is pretty easy to tamper with vs a movement number for instance), there is no way I can think of to tell two watches apart...
