Thank you Alex for your reply , it is in fact a 4240 with pink gold and roman numerals .
I have 2 questions to ask you because of a disaster which happened to it in September 2007 .
1. Do Vacheron-Constantin in Geneva keep records of watches sold as far back as those days as it was purchased in Lausanne or Geneve ?
2. Is it possible to to tell anything from the numbers inside which would indicate the authenticity of the watch and parts ?
Briefly I gave my watch to a repairer to clean up and adjust the winding mechanism and he confronted me 1 week later with an envelope containing $3800-00 telling me I had agreed on a phone conversation with him to sell it to a lady who had already left for Greece !!!!!! I immediately went to the Police and have won a court case against him despite having had no receipts . Now if he tries to return " Any watch whether a replica or not " how am I to judge and verify parts have not been removed or tampered with .
Basically this is the nightmare scenario .
He gave me some seial numbers with the money but I doubt their authenticity a] Boitier No. 287445
b] 489719 on parts .
calibre 455 and Suisse with an arrow and 143 inside it .
I would appreciate any suggestions .
