As a vintage buyer original certs are pretty hard to come by. Extract from the archive are imho just as good. I also have a few modern PP with box and papers. The box and paper work have been stored in my closet and I have not looked at them since I purchased the watch. True full set is worth more. But then if you are on the BUY side of the deal the watch with just an Extract should be worth less. You will not look at your box or cert.
