Guide to Audemars Piguet Serial Numbers & Reference Numbers

How to Find Your Serial Number

Like many products, watches are furnished with serial numbers and reference numbers. Serial numbers are unique to each watch and can sometimes be used to date the production period. On the other hand, reference numbers (also known as model numbers) denote the specific model, and in some cases, they can also reveal other details such as material, size, color, bracelet type, and so on. When shopping for high-end watches, it’s important to have a basic understanding of serial numbers and reference numbers. This is especially vital when purchasing pre-owned luxury watches to ensure that what you’re buying is indeed correct. Every brand has a unique system, so here’s a comprehensive guide to understanding Audemars Piguet serial numbers and reference numbers.

Audemars Piguet Case Numbers

Do you ask yourself, what year is my Audemars Piguet Watch?

Every watch produced by Audemars Piguet features unique case and movement numbers, and the brand keeps a record of these numbers. In fact, you can order an Audemars Piguet Extract of the Archives with the watch’s serial number. The movement number is engraved on the mainplate of the movement, which can only be seen if the watch has a transparent caseback or if the back of the watch is removed. Conversely, the AP case number — also known as the Audemars Piguet serial number — is engraved on the outside of the caseback. Since 1972, AP serial numbers start with a letter followed by numbers. This alphanumeric engraving is unique to each Audemars Piguet watch, and letters can estimate when a watch was produced. The serial number can also be found on the warranty certificate or warranty card.

How to Find Your Serial Number This is not official AP data, but rather, approximations compiled by watch collectors and enthusiast over the years. Above are the series lettering, as originally posted on Rolexforums: It’s important to note that sometime in 2019 (around the 4th quarter), Audemars Piguet stopped using sequential case numbers and switched to random case numbers. Therefore, if the watch has a random case/serial number, it cannot be used to date its approximate production period. Some AP watches also have the sequential production number above the case number, which starts with “No” followed by numbers. This indicates the nth piece (for example, the 500th piece) produced of that particular model in that particular metal. Sometime in 2017 with the J serial, AP stopped engraving the No number on the casebacks of its watches. When shopping for high-end watches, it’s important to have a basic understanding of serial numbers and reference numbers. This is especially vital when purchasing pre-owned luxury watches to ensure that what you’re buying is indeed correct. Every brand has a unique system, so here’s a comprehensive guide to understanding Audemars Piguet serial numbers and reference numbers.

Audemars Piguet Reference Numbers

The complete reference number of an AP watch not only tells you the specific model (for example a Royal Oak or a Millenary) but also includes material, collection, and dial codes.

An Audemars Piguet reference number is typically structured like this: #####XX.XX.####XX.## where # represents a number and X represents a letter. For example, 15400ST.OO.1220ST.02.

The first numbers are the model number followed by letters that denote the case material. The most common letters you’ll find in Audemars Piguet reference numbers are as follows:

BA – Yellow Gold
BC – White Gold
CB – White Ceramic
CE – Black Ceramic
IO – Titanium and Ceramic
OR – Rose Gold
PT – Platinum
RO – Rose Gold and Ceramic
SA – Steel and Yellow Gold
SO – Steel and Ceramic
SR – Steel and Rose Gold
ST – Stainless Steel
TI – Titanium

The next pair of letters in the AP reference number is the bezel code. The most common bezel codes in Audemars Piguet reference numbers are as follows:

OO – Smooth Bezel
ZZ – Diamond-Set Bezel
YG/YY – Colored Gemstone-Set Bezel
GG – Frosted (Hammered) Gold Bezel

The following set of numbers and letters is the bracelet and/or strap code. Again, the letters denote the material of the bracelet, which in many instances matches the case material letters. However, there are a few additional non-metal bracelet material abbreviations to know:

CA – Rubber Strap
CR – Leather Strap
KB – Rubber-Coated Strap
VE – Calfskin Strap

Finally, the last two numbers in an Audemars Piguet reference number is a dial code, which is different for each model.
While the entire AP reference number is composed of 17 digits, each model is often referred to only by the first set of alphanumeric codes. For example, ref. 15400ST, ref. 26420SO, and ref. 15210BC.
Audemars Piguet reference numbers are not engraved on the watch, but you can usually find them on the watch’s accompanying paperwork.

Buying Audemars Piguet Watches

Unless you’re buying an Audemars Piguet straight from an authorized dealer or AP boutique, there’s always a risk of ending up with a replica, modded, or franken-watch model. This is especially true when looking at secondhand Audemars Piguet since the values of these ultra-luxury watches are so high right now.

This is why it’s important to understand Audemars Piguet serial numbers and reference numbers. The more you know, the better equipped you are to make the right choices when purchasing an Audemars Piguet watch.

And remember to always “buy the seller” — only buy luxury watches from reputable, trustworthy, and knowledgeable dealers, such as Precision Watches, to ensure that you are getting what you’re paying for, safely and securely.
