The case for a service history

Consider a vintage dress watch — a 1960s reference from a great Geneva house. The watch looks immaculate. The case is sharp, the dial unblemished, the movement clean under loupe. On paper, it is everything. Then you ask about the service history, and the seller pauses.

"It's never been serviced. Original everything."

This is the moment that separates an experienced buyer from an optimistic one. An unserviced vintage watch is not a virtue — it is an unknown. The lubricants applied at the factory in 1964 have been degrading for six decades. Whether the movement has reached a safe threshold of degradation, or whether it has already begun to damage itself, cannot be answered by looking at the dial.

A documented service history — dates, the name of the watchmaker, ideally the maker's stamp on the movement — transforms an unknown into a known. It tells you that a trained technician saw the movement at a specific date, assessed its condition, and either serviced it or did not. Either conclusion is valuable.

Papers matter too, but differently. An archive extract — the document a manufacturer issues confirming the reference, the metal, the original strap, and the date of sale — is a form of birth certificate. It tells you what the watch was when it left the manufactory, and by comparison with what sits before you, you can judge what has changed.

The watch listings that deserve your most serious attention are not the ones offered with nothing but a seller's assurance. They are the ones that come with service records going back thirty years, with extracts, with the boxes they were born in. Not because condition is everything — but because documentation proves that someone else cared about this object before you.
