I am not shure that this one is a fake. I have seen a lot of them for sale in Germany and Switzerland. Some NOS and some used. They have many things in common with other of the unloved French made chronographs.

Many will remember the much discussed Champion marked Heuer http://www.onthedash.com/Guide/_Chronographs/70s_Chronographs/Reference_741-1/ It has the same oversized ugly looking Heuer logo and if I remember correct, a unsigned Valjoux 7734.

The little known ref. 3006 has the same ugly big Heuer logo and unsigned Valjoux 7734. See: http://www.onthedash.com/Guide/_Chronographs/70s_Chronographs/Reference_3006/

The one discussed at TZ-UK has the same hour and minute hand as ref. 3006 and ref. 12. The ref. 12 also has the big ugly Heuer logo and usigned Valjoux 7734.

And the one discussed at TZ-UK has the C + number marking on the caseback. That tell's us that it was sold by Heuer in Switzerland. Se pic from TZ-Uk below.

My 2 cents is that this a real Heuer from a time when Heuer did make a lot of different cheap looking chronographs using unsigned Valjoux movements.

No one belived that ref 741-1 and ref. 3006 was real when the first shoved up. I think this one is in the same category.... But again, I could be wrong... :-)
