Thanks for the post, will let you know what happens, I took the watch in a couple of weeks ago (they still think its gen) so its too late now anyway.
As I said they are not Omega dealers so I didnt envisage any issues with it being a rep, if they can't spot one thats not my problem, as I got it from a car boot sale if they ask!
They way I see it a broken watch is useless to me so I may as well at least try to get it fixed.
