A fine watch leaves a paper trail that few owners have considered in full. The trail begins at the manufacturer, who recorded the serial number, the original retailer, and the date of delivery. It continues with the retailer, who registered the warranty in the buyer's name. It continues with the service centres, who keep records of every visit by the watch over its lifetime. It is added to by the auction houses, who catalogue the watch with photographs and provenance when it is sold. It is reinforced by the specialist press, who write about important pieces and the collectors who own them.

For the owner of a serious watch or a collection of them, this trail accumulates against their name in places they tend not to think about. The warranty card from a purchase fifteen years ago is still on file at the retailer. The service record from ten years ago is still at the manufacturer. The auction catalogue from when the watch passed through the trade is still in libraries and on auction-house websites. The photographs of the owner wearing the watch at events are in the social photography of the relevant publications.

Individually, the entries are unremarkable. Read together by someone with an interest in the owner's holdings, they describe the collection with considerable accuracy. They also describe the patterns by which the owner acquires, services, and disposes of pieces, which is information of its own kind. A capable observer can, from the trail of a single watch, reconstruct a substantial part of the owner's relationship with their collection.

The watch itself, like the file, cannot be unwritten. What can be addressed sits in the records that surround the trail. The aggregators that index auction catalogues. The publications that hold the social photography. The retailer's and manufacturer's records, which in most jurisdictions can be reviewed by the customer they relate to under the relevant privacy framework. The desk's work in this area is at this layer, through the proper channels.

the desk works with substantial collectors across the watch, art, car, and instrument markets. The fuller account of the approach is in the desk's work on protecting collectors and the things they hold.
