dvn my friend,
I honestly cannot tell, maybe By-Tor can be of more help. My only concerns are this seller only as 11 feedbacks, but NONE as a seller. I would pay with PayPal and take the watch to an authorized Omega dealer IMMEDIATELY! If it is in fact not gen contact PayPal immediately. Also contact Omega with the serial no. I just can't see a watch like that going for that low a price and the description says nothing about it being genuine. I sincerely hope it is gen and you got a great deal.
