I'd appreciate a little expert advice here. I recently bought a Heuer listed on Ebay. The seller insists that it is genuine, and he has owned it since new. I have my reservations.

The first thing I noticed was that the back inner casing is marked "Itika Watch". Now I know very little about Heuer, but that doesn't sound right. The dial looks fine, but the movement doesn't look right to me - it's a Calibre 7734 movement.

The seller says it's genuine, and has been serviced by Heuer, and we both acknowledge that the strap isn't Heuer, but what about the watch itself?

I've supplied the following pics, scaled down a little (300x400) as I do not want to bombard people with huge pics. It would sincerely be appreciated if anyone can help and advise.
