Id return it if at all possible.
There’s a UK seller churning these out in high numbers and his description is very economical with the truth, to the point of being borderline deceitful.
No Omega watch left the factory looking like that. It’s basically a low quality, repainted dial with aftermarket hands which takes all the collectible and desirable aspects of a range of vintage watches and throws them into one big pot, mixes them all together, with the result being this monstrosity. Sorry to be so blunt, but it’s complete junk in my opinion.
I’m assuming you bought it on eBay, so unless you still like it, a return should be no problem.
