Since its founding in 1875, Audemars Piguet has been synonymous with Swiss watchmaking excellence. Each timepiece not only embodies meticulous craftsmanship but also carries a unique serial number—a subtle yet significant identifier that reveals its authenticity, production details, and historical context. For collectors, understanding these serial numbers is essential in tracing the lineage and verifying the legitimacy of their cherished watches.
Understanding Audemars Piguet Serial Numbers
What Is a Serial Number?
A serial number is a distinct alphanumeric code assigned to each AP watch. This identifier serves multiple purposes:
- Authentication: Confirms the watch’s legitimacy.
- Dating: Indicates the production year.
- Servicing: Assists in maintenance and repairs.
- Valuation: Helps assess market value and provenance.
Where to Find the Serial Number
The location of the serial number varies depending on the watch’s age and model:
- Modern Watches: Typically engraved on the case back or between the lugs.
- Vintage Models: Often found on the movement itself, necessitating professional disassembly.
- Documentation: Warranty cards and certificates usually list the serial number.
Decoding Serial Numbers by Era
Pre-1972: The Numeric Era
Before 1972, AP employed a purely numeric system. These numbers can often be cross-referenced with production records to determine the manufacturing year. For example:
- 1892: Serial numbers 4341–4505
- 1900: Serial numbers 6295–6724
- 1950: Serial numbers 56705–56716
*Due to historical record-keeping practices, some serial numbers may not follow a strict sequential order.
1972–2017: The Alphanumeric Transition
In 1972, coinciding with the launch of the iconic Royal Oak, AP introduced an alphanumeric system:
- A Series: 1972–1975
- B Series: 1976–1979
- C Series: 1980–1986
- D Series: 1987–1994
- E Series: 1994–2000
- F Series: 2001–2007
- G Series: 2008–2010
- H Series: 2011–2012
- I Series: 2013–2015
- J Series: 2016–2017
Each letter denotes a production batch, aiding in dating the watch.
Post-2017: The Randomized System
In 2017, AP transitioned to a more complex, randomized alphanumeric system to enhance security and prevent counterfeiting. This system no longer follows a sequential pattern, making it more challenging to deduce production years without official records.
Movement Numbers: The Heartbeat Identifier
Beyond the case serial number, AP watches also feature a movement number:
- Location: Engraved on the movement’s main plate.
- Purpose: Identifies the specific movement used, crucial for servicing and authenticity.
*Note: Accessing the movement number typically requires opening the case back, which should be done by a professional.*
