I think your dial is original, but it looks like someone attempted really poor restoration on it and it now needs to be tossed. Normally you see the outer layer of the dial deteriorated and you lose the text or minute marks on these dials, but in this case it looks like someone tried to cover it up with paint or something - like when someone tries to cover up grafitti on a highway bridge.
Not a huge deal in this case, as Omega still makes a service dial that matches yours. You can even snag one on ebay:

very selective about who touches the case, as I've seen Omega trash Mark III cases. I'd want a new bezel but prefer to keep the hands original (at least the needle-tipped minute hand anyway - so maybe you also need to have the hour hand repainted as well). Good luck! I hope to see the "after" pics soon!
