Help with servicing 1956 6593

[moment1]

Hi guys, so a few months ago i bought this 6593 in Netherlands.
I took it to Rolex Barcelona, where they are returning the watch with a note that they wouldnt do anything, Geneva headquarters is the only place where they would.
Its obvious the watch needs oil. I wouldnt know about anything else.
The biggest problem is that i dont know if everything is original.
It would only seem worth it putting the money under to preserve this watch if its authentic.

Rolex spain wasnt helpful at all. I guess they can send the watch to Geneva, but im not familiar with the processes and pricing.

Are there some suggestions what i should do and not to in this case, to find out if the watch is original and how to service it.




Thanks alot

Im new, so right now its a hard spot for me.
I have this watch, Rolex told me Geneva is the only place, but there people always pay many many thousands.
Considering i paid 3.5k eur for this, and im also ready to pay quite a bit to have this maintained, just is Geneva my only option?
Or is it not worth the whole deal and i would just buy a new one.
