I bought an Autavia Ref. 73463 (Siffert Style) from that seller recently ...

On that watch (the Autavia), several parts had been replaced, too. Some very clearly visible from the picture in the auction (especially the pushers), but several only became obvious when I received the watch a week ago. The crown is too small, there is about 1 mm space between the crown and the case. The hand for the second isn't original (too thin), the bracelet might not be original (although the clasp is signed, the connecting bit, sorry, don't know the English word, reads "Stainless Steel China"). Still a good watch for that price. Didn't find the seller very friendly though. He repeatedly insisted that everything is original and urged me to pay. Which I did, but I just asked whether he could get original pushers for the watch. Especially since he said that he had just bought several Heuer watches from one customer.

I might start a new thread on this Autavia soon. I just mentioned it here because it was the same French seller, watches-mania.
