I hope I didn't mess something up on the forum! I don't know why, but it took me three posts to get my pictures to load. Since then, there have been no new posts or answers to my post. If I did something wrong, I sincerely apologize--I enjoy this forum and don't want to see anything happen to it!
To answer your question: I don't know, but the style and the fact tht it has a 4 digit case reference number makes it "plausible". It all depends on the quality of the dial. It you are certain it is not refinished or has Cartier added, then it has a good chance of being real.
