What have you already found out yourself on this watch?
I meant: the 4th pic on Google when you type in 'Omega De Ville vintage' -you said it is an old watch- gives you rather much info on the watch.
Case looks the same, although yours is SS and movement on Google is automatic, but it will start you up quite nicely. Gives you info on the approx date etcetera.
We usually love to learn here... 📖📖
I'm not sure as there are lots of models similar to this.
It does look like a 60s Omega De Ville Manual wind so, likely a 601 calibre. Try searching including the "601" and it might get you closer.
I see Willem has answered as well when I was typing.

I don't know what country you're in but there may be one not far anyway. Search this forum for recommended Watchmakers. I'm guessing that as you used 'basement', you're in USA and there are plenty of people on here who are also there.
That does look like it. When it's serviced, you can wear it everyday.👍
Cheers, Chris
