Does this look like a redial and are the hands correct?

I don't know, what they have been using. This not a spectacular model. They show up to actual models and they also show older ones in original condition with scratches and patina.

It does not seem, that Omega shows repainted dials in this book and in my opinion, they should be able (if necessary) to restore a dial, like it should be. And if not, they grab into their storage and take a new one...

And furthermore there are professional restorers, who have access to the original printing plates, like

They have over 60.000 steel printing plates for different models
