Where is the serial number on a Vacheron Constantin watch?

Movement and case numbers are separate series; Vacheron Constantin's extract service is generally movement-number-based, and a case number alone, without the corresponding movement number, may not retrieve the same depth of archival record.

What do Vacheron Constantin serial numbers mean?

Where a movement number is checked against the company archive, the extract can confirm the manufacturer's own recorded original specification (such as case type, complications and, for some periods, original retailer or destination); this documents what the company recorded at the time, not the watch's subsequent ownership or service history.

How accurate is dating a Vacheron Constantin watch by serial number?

Verified when obtained via the official Extract from the Archives; estimated at best when relying only on unofficial public serial charts, which exist online but are not authoritative in the way the manufacturer's own archive is.

Where are Vacheron Constantin production records held?

Vacheron Constantin holds one of the more complete surviving manufacturer archives in the Swiss trade, covering much of its production since the late eighteenth century, and offers an official 'Extract from the Archives' certificate referencing these original records, generally keyed to the movement number.

Limits

What the number does not prove

Do not assume a case and movement pairing is the original factory configuration simply because both carry period-plausible numbers — request the extract to confirm the recorded pairing where authentication matters.
Do not treat the archive extract as proof of unbroken originality of every component; it documents the recorded original specification, not an inspection of the watch as it exists today.
