i haven't been on ebay since posting this watch up last week, it was given to me as a present and was bought somewhere in asia. It has never been worn, i took it to a jewelers yesterday after all the questions about authenticity and they told me they would have to dismantle the watch to check if it was the real mccoy or a replica hence its quality. i was unaware how expensive these watches were when i posted it up but i can assure bidders the watch i have here is in excellent condition and looks the part !!

It looks like there are at least a few people happy to own something in excellent condition from "somewhere in Asia". Although they could probably get one cheaper by doing another search on Ebay...
