As Bigfoot says, be very careful buying watches on eBay. I also checked the watches on eBay for a few months before buying (from an authorised dealer). There are definitely fakes out there, and most of them are worded like the one quoted by Wishtobeflying. They usually state that the watch was a gift so they don't know the history, have no idea of the value (like it's so hard to find out), and have no papers. Then they describe what is written on the watch without ever claiming it to be genuine.
