There might be some value in a receipt with the customer's name on (not many receipts actually have this) and it was that same first owner selling to me....but it still would not guarantee that the watch had not been reported lost / stolen by that same person, fiddling their insurers, nor would it prove that it was the same watch in all its parts as the one which had been originally bought.
Receipts, papers.....they don't actually serve much purpose and certainly shouldn't provide all the assurances which are perceived and perpetuated merely through being restated by the ignorant on watch fora daily.
Will I charge more for a watch with papers? Of course, because I am a dealer and if buyers value a watch with papers more highly than one without, I will serve the market however potty its rationale --- and I will have had to pay that little bit more myself, too.
It is nonsense upon stilts!
