Hello fellow TAG / HEUER owners and enthusiasts. My late father was a collector of vintage / retro pocketwatches and watches and amongst his collection he had a "well used" Heuer Carrera which he used to wear and which I think is 3rd Generation "Barrel" case, Calibre 12 or 15 movement with a Cotes De Geneve dial? Possibly a Carrera 1158CHN but the dial is different in that the "12 noon" is a single point and the "9" and "3" do not have luminous dots but a straight black line instead? The case is slightly dented in several small areas showing how soft the gold metal is and the glass face is damaged. The black second-hand sweeps majestically and silently and is wound up by wrist movement apparently. It has a MONTAL rolled gold band strap (not original I'm guessing). I would be grateful if anyone could advise what "model"/ year etc. or whether they are aware of others still in existence? Many thanks - photo attached.
