Box and Papers: What to Keep

What counts as papers

The exact set depends on the maker and the year, but collectors usually mean:

• The warranty card or certificate, often dated and stamped by the retailer.
• The original sales receipt or invoice.
• Instruction booklets, warranty booklets, and any chronometer certificate.
• Hang tags, swing tags, and the outer and inner boxes.
• Later paperwork that belongs with it: service invoices, extract letters from the maker, and appraisals.

Why they matter

Papers are part of a watch's provenance: they connect a particular watch to a date and a place of sale. A complete set gives a buyer, an insurer, or an heir more to go on than the watch alone.

They are not proof on their own. Papers can be lost, swapped between watches, or faked, so what matters is that they match the watch. The serial number on the card should match the one on the case, and the reference should match the model.

How to record them

A record of the papers protects you if the originals are ever lost or damaged. For each watch:

• Photograph every item flat, in good light, front and back.
• Note what the set includes and what is missing. "Card and booklets, no receipt" is a useful line.
• Check privately that the serial and reference on the papers match the watch, and note that you did.
• Write down where the originals are kept.

Store the originals apart from the watch

If the watch and its papers live in the same drawer, one loss takes both. Keep the papers in a dry, dark place away from the watch, and keep your photographs somewhere else again.

Warranty cards and receipts fade in sunlight and stick together in damp. A simple archival sleeve for each card is enough.

Sharing papers when you sell

Buyers will want to see the papers. Show photographs first with the serial number covered, and reveal the full number only once the sale is agreed and you know who you are dealing with.
