A full set means the watch, its original box, and the paperwork it was sold with. The phrase gets repeated constantly in watch listings and almost never explained, so here is what each part actually does.

The card is doing the heavy lifting. It is the part that links a specific serial to a specific dated sale, which is exactly what a careful buyer wants and exactly what is hardest to fake convincingly.
It is about risk, not sentiment.
A buyer paying serious money for a watch is pricing in the chance that something about it is wrong. Redialled, wrong bezel, replaced hands, a case polished so many times the lugs have lost their shape. Every one of those costs money to discover after the fact.
A dated card and a coherent service history do not eliminate that risk, but they narrow it considerably. What you are being paid for is the reduction in uncertainty, which is why the effect is largest on the references where the downside is biggest.
By brand and by reference.
- Rolex is where a full set moves the number furthest, particularly on sports references.
- Patek Philippe and Audemars Piguet behave similarly at the top end, where provenance is a large part of the purchase.
- On a mid-market watch the effect is real but smaller, because the downside risk being insured against is smaller.
- On vintage the picture flips somewhat: originality of the watch itself starts to outweigh the paperwork around it.
Original beats immaculate.
A watch with an honest, untouched dial and visible wear is very often worth more than the same reference refinished to look new. Refinishing removes original printing and it cannot be undone. Overpolishing rounds the case edges and takes metal off permanently.
If you are thinking about tidying up a watch before selling it, do not. Bring it as it is and let us tell you whether the work would add anything. Most of the time it takes value off.
It is not a disaster.
Plenty of good watches have no paperwork, and they still sell. It changes the number rather than the outcome. What helps in the absence of papers is everything else being coherent: matching serial and reference, an original dial, the correct bracelet, and a movement that is what it should be.
Bring the watch and whatever came with it, including anything you were about to throw away. We will tell you what your set adds before you decide anything.
