Servicing by RSC vs trusted sellers

[harrishc]

I just picked up a good condition 16750, but it does have some signs of use and I m thinking about bringing it in for a slight polish. Apologize for all the newbie questions as I m new to the world of vintage Rolexes.

1. My watch has no paper, does it matter if I take it to RSC?
2. It has a replacement plexiglass, will this be a problem? My seller insisted me that most vintage pieces have replacement plexiglass, is this really the case? Will RSC replace it with factory plexiglass?
3. For polishing, does RSC do a significantly better job than others?

Any thoughts?
