Is this beautiful vintage Omega De Ville real or fake?

Hi,

I recently purchased an vintage omega de ville watch off ebay, as I was drawn in by the roman numerals. I just wanted to get an opinion if it is authentic:

According to the listing, it's reference number is 151.0039 which according to the Omega database would put it's date of production around the 1970s.

I found the same(?) model being sold as spares,

and a key difference is the "De Ville" lettering, and it seems that the one on mine is markedly differently, and I have a feeling that it is a refinished dial. What do the experts in this forum think? Real, refinished dial, or complete fake?

Also, how should I go about searching for a replacement stone for the crown or replacing the crown completely? Cheers!

Appears to be authentic.

That's a genuine Omega caliber 711 in a genuine Omega case from what I see. Whether or not the dial is refinished I can't tell you due to unfamiliarity with that model. Probably easier to find a whole new crown instead of just the cabochon.

Well, I learned something today.
