I'm by no means an expert at all, but I thought I would put my input in. To me personally, it does look like a redial yes, the "R" is a huge giveaway in my opinion. I am also a little concerned by the "M" in the Omega logo, looks a little broad to me, but as I've said that might just be my untrained eye! Don't really take my word for it, wait for one of the more respected enthusiasts to take a look, they'll be able to tell straight away. May also help if you added some larger/more photos of the face. Hope you find out the REAL answer!
I'll defer to the expert. Would have fooled me though, at least with that picture. OP, I would listen to hoi, he has much more experience than I.
