Box and papers explained

Listings for pre-owned luxury goods are full of shorthand: full set, box and papers, watch only, with certificate. These phrases describe what comes with a piece, and they matter. They are also widely misunderstood. This guide explains what each one means, what the documents are for and why none of them, on its own, proves that a piece is genuine.

Watches

Box and papers means the watch comes with its original presentation box and its warranty documentation. For many houses the papers are now a warranty card, sometimes digital, that records the watch's serial number and the date and place of first purchase. Older watches came with paper certificates and guarantee booklets.

Full set usually means everything the watch came with: inner and outer boxes, warranty card or certificate, instruction booklets and sometimes swing tags, spare links or a chronometer certificate.

Watch only means just the watch. This is very common on older pieces. Boxes were thrown away, papers were lost in house moves, and a watch that has been worn for decades often outlives its paperwork.

Service papers record work done by a watchmaker, such as a service, a new crystal or replaced parts. They are not the same as original papers, but they are a useful part of a watch's history.

Bags

A handbag's set typically includes a dust bag, sometimes a box, and any original accessories: a shoulder strap, a padlock and keys, a clochette, a rain cover, a care booklet or an authenticity card. What comes as standard differs between houses and has changed over the years.

Authenticity cards deserve a special note. Some houses have issued cards with their bags; these are among the most counterfeited items there are, and a card can easily be paired with the wrong bag. The bag itself carries the evidence that matters: construction, materials, stamps, codes, microchips on recent pieces and the quality of every stitch. Our guides to Chanel Classic Flap authentication and Louis Vuitton date codes and microchips explain this.

Jewellery

Fine jewellery may come with a box, a pouch, a house certificate and, for larger diamonds, an independent grading report. A grading report from a laboratory such as GIA describes a stone's characteristics; it does not describe the setting or the maker. Many reports have their number laser-inscribed on the stone's girdle, which a jeweller can read under magnification and match to the report. Our guide to reading a diamond grading report goes into detail.

Why documents never prove authenticity

There are three reasons we treat documents as supporting evidence only:

1. They are copied. Boxes, cards, certificates and receipts are reproduced at least as carefully as the goods themselves.
2. They become separated. A genuine box and genuine papers can be paired with a counterfeit or a different item.
3. They can be altered. Details on paper can be changed; the engraving on a case or the stamp in a bag cannot easily be changed without trace.

So we examine every piece itself and then check whether its documents agree with it. When they do, they add to its history. When they do not, we say so, or we do not offer the piece.

Does a full set matter?

For an owner, a full set is pleasant: it completes the story, it makes a piece feel whole and it can help with future servicing or insurance. For a buyer, it is one consideration among many. A watch-only piece in good order, properly authenticated and honestly described, can be the better choice over a full set with a doubtful history.

How we describe inclusions

Every listing in our shop states exactly what is included, and only what is included. If a piece comes without its box, we say so. If papers are present, we say what they are. We never describe accessories that are not there. Read our authentication overview, our guide to buying pre-owned safely, or browse the shop.
