That appears to be an early 50s US Collection watch.
There are a number of paths you can follow depending on your goals.
If you want it to look like brand new, Omega servicing might be your choice.
If you want to wear it and keep it in its condition now, then an independent watchmaker might be your choice.
If you want to keep it and not wear it, then doing nothing might be your choice.
Knowing where you live can help us direct you to (one hopes) a local watchmaker, but decent watchmakers are few and far between, so you might need to mail it out.
This is a good watch and will, once it is restored, serve you decades.
