: Thanks so much your reply and interest. I got this watch from a retired watchmaker who finally opened up his box of "stuff"....plus an Autavia 73463 a Carrera 2 register with 7733 and the prize (I hope) is a really sharp Monaco 1133B on original band and incredibly so the original box!. The strange thing is that the ref 1133 has been overwritten with a serial number. Both still visible..My watchmaker had no answer but all is 100% Heuer! Anyway thanks again. Brian
I will probably part with most but undecided
: with this Carrera 12 Dato, you have found one
: of the rare and collectible ones. We see
: just a few of these per year.

: Yours looks like a very nice sample. So is
: there a story or adventure in how you found
: this one?

: Thanks for posting your messages and photo.
