Hi,
I am relatively new to collecting Heuer watches, although, I have been an admirer for more years than I care to remember.
I must say, the information available via your combined web sites and forums is staggering, well done, but as always there is bound to be something someone needs advice on.

Can anyone help me regarding Camaro identification/authentication. I have been offered what appears to be a nice condition Camaro 9220NT from 1968, the case is stamped with the serial number between the strap lugs as normal but is not stamped with the model number. ls this ok, as all the Camaro's I have seen have both serial and model numbers stamped on the case?

The watch also comes with a 1967 style Warranty/Instruction booklet with one partially completed warranty page, this shows the purchase date and a reference number, which I do not reconise, in the watch model box.
The seller (a well known reputable dealer) feels the number was the original dealer's stock number, is anyone aware of this being a possibility?

Again, regarding identification, do the codes on the back page of later type Instruction/Warranty Booklets refer to the year of printing i.e.:
G/CH 11.78.4000.1 (1978?)
083.200.0004 (1983?)
083.3.0004 (1983?)

Any advice or comments would be much appreciated.

Many thanks,

Ken
