RSC versus independent (uk)

[colpol]

I’ve had my 1680 for coming up on 6 years - service history unknown

Looking to put it in for a service sometime late Feb/ early Mar

Been on here long enough to have heard the horror stories of dials, hands etc being swapped out during servicing

Question : i got my 16600 serviced 3 years ago via a local AD which was fine. If I was to bypass the local AD & go direct to RSC London ask for a movement only service insisting on no dial/ hands/ bezel swap outs / nor polishing. Would they do or return watch if they felt those parts had to be replaced & therefore couldn’t guarantee the work ?? My watch was purchased from seller with excellent rep but would be nice to have rolex service papers as I don’t have anything else to guarantee the authenticity of the watch

An independent I’ve heard good things about is William Rice but I then I wouldn’t have the RSC papers

Interested on your thoughts
