I am not sure of the reference number, but it appears to be identical to the Reference 346 chronograph, except that the Reference 346 is stainless steel.

I believe that the Reference 346 dates from the mid-1940s, and it has the round (waterproof) pushers. The Reference 345 looks similar, but has the flat pushers (so not waterproof).

I am posting this from the iPad . . . will try to add the catalog images and also study the serial numbers when I can get onto a real computer.

: On behalf of a friend I present an interesting and rare 18 karat
: gold Heuer that both he and I would love to get some opinions on
: from those in the know. My Heuer collection and knowledge starts
: from 1962 so this one required some research which in the end
: proved inconclusive.

: I have not found this example in any of the old catalogues on this
: site which makes it all the more difficult to pinpoint a date of
: production and a reference number. The styling of the hands and
: dial suggest 1940’s yet case with serial number seem to point
: to a later production date.

: So if you know more on this one please share your knowledge with us
: and the wider Heuer community.

: Best regards
