Used gray watches - do they all look polished to you?

[fixinbones]

If you look at the Rolex classifieds all of the second hand watches from the grays look to be in perfect condition. Bracelets and clasps have no scratches and some of these are not recent purchases or flipped trade-ins. So are they just touched up and gone over slightly to remove obvious scratches or are these watches refinished and brought back to as new condition?
