Could you help me ID this vintage Rolex, please?

[Sylvia]

Hello. I am new to this forum, and I would sincerely and gratefully appreciate your knowledge, because I have tried my best to research this, and I am unable to identify this Rolex. It has been passed down to me by my late uncle, who told me that he bought it at a flea market in Rome in the mid-eighties. It works fine. I am attaching some pictures. There are so many numbers (some appear written on top of others), it is all quite confusing for me.

If possible, I would like to know what model it is, and if you can, its date? I would be happy and willing to have it cleaned and serviced, if you think that would be a good idea. I turn to this forum for expertise and guidance.

Thank you.

(one of the pics looks orange -- in reality it the stainless steel color like the other pics...)
