Rolex papers, boxes and condition.
IMHO box and papers are a plus when buying a vintage 4digit Rolex (especially the prices correct boxes and bits are fetching, for certain models). However, Condition is the paramount factor. I would always chase condition and originality over paper work and boxes.
Choice, minty watch no papers average watch full set?
If it’s a younger 5digit reference or later model have Rolex service it without a polish if so desired, for some paper work if you are going to move it on later and piece of mind.
