Key points
- For a watch collection, the reference and the serial number are worth more than any description.
- The box and papers, invoices and service records are part of the watch: they affect its value.
- A complete file lets you value a watch, insure it properly and trace it after a theft.
Watch collection: what to keep track of
Two watches from the same brand can look alike and yet have neither the same history nor the same value. What sets them apart comes down to a few engraved numbers and a few papers: reference, calibre, case number, original certificate, service invoices. Keeping an inventory of a watch collection means noting this information once and for all and storing the evidence in the same place.
Tracking does not stop at the purchase. A mechanical watch is serviced, a warranty expires, a strap is changed, a watch goes to the watchmaker for several weeks. These are all events to date, because they matter on the day you want to sell, insure or pass the watch on.
What a watch record contains
| Field | What it is for |
|---|---|
| Brand, model, reference | Identify the watch precisely and find comparables for the valuation. |
| Serial number (case) | Prove that it is your watch; essential for the police report and the insurer after a theft. |
| Calibre or movement | Tell similar versions apart and prepare a service. |
| Case material, complications, strap or bracelet | Describe the watch as an expert would. |
| Diameter, thickness, lug width | Complete the identification; choose a strap. |
| Box and papers (complete, papers only, box only, none) | An important criterion for resale value. |
| Warranty until | Do not let free coverage lapse. |
| Last service and maintenance invoices | Show that a watch has been maintained; know when the next service is due. |
| Photos and documents | Dial, case back, movement, hallmarks, papers: the most convincing evidence. |
Pocket watches, clocks and timepieces have their place in the same category, with the same fields.
Valuing a watch and insuring it
To value a watch, a professional will always ask for the same things: reference, serial number, condition, box and papers, maintenance history. Having everything to hand saves time and avoids approximations. Keep the history of valuations, dated and signed, rather than a single figure.
As for luxury watch insurance, home policies often cap valuables and impose protection conditions. If your collection exceeds that cap, an extension or a specialist policy is needed; our guide agreed value or declared value explains what changes in the event of a claim. After a theft, the reporting period set by the policy cannot be shorter than 2 working days: better to have the file ready. The advice in our guide on jewellery theft without an invoice applies to watches too.
Succession
Watches are often handed down from person to person, which is precisely the source of the difficulties: nobody remembers who received what, or what the great-grandfather’s watch was worth. A documented inventory, with your wishes for each watch (who should receive it, whom to entrust with its service or sale) and the papers stored with the record, simplifies the work of the heirs and the notary (notaire). For the tax treatment in an estate, consult your notary.
Photos from your phone and sharing
Photograph the watch lying flat, in soft light: dial, profile, case back, clasp, then the box and each page of the papers. To have a watch valued or to offer it to a buyer, share a selection through a password-protected, time-limited link rather than sending serial numbers and photos by messaging app.
