Genuine? Where to get it cleaned up?

[jwakeman]

Long-lurked, first post.

Trying to find out whether this watch is actually a Rolex? It is the proverbial, cleaning out my grandmother's dresser and found this with a number of other vintage watches. I see what I think are 5050 and 662,xxx on each side of where the straps would go.


Would appreciate some guidance on who could give this (and possibly some of the other watches I found) a good once over without ruining the existing patina to make an occasional wearer?

Thanks!
