Hi Jean
thanks for your Replay ,I was their on the vintage department and the watchmaker told me that they have two differents hands the service hands and those hands and I ask him to change to the Original but he confirm that this type is also a original from the 70`s but now after so many research those hands seems to be a replacement and we never see a Old Heuer brochure with those hands .they change me the Hands and the Dial and they give me all the changed parts .but now Tag Heuer Switzerland have a New reglement they give not the old part back they keep it ,perhaps they want produce a new part of stock????
Regards from zurich
