Locating the Numbers on Your Rolex
Where to Find the Reference Number
Focus on the 12 o’clock side (top) of the watch case. You will observe a Reference Number located along the case’s edge. Precisely, it is just nestled under the bracelet.
Where to Find the Serial Number
The location varies based on the age of your Rolex:
- Pre-2006 models: Engraved on the 6 o’clock side of the case (opposite the reference number).
- 2006–2008: Located both on the case at 6 o’clock and on the rehaut (the inner ring under the crystal).
- 2010 and onwards: Only engraved on the rehaut at 6 o’clock.
Decoding the Rolex Reference Number
Rolex Reference Numbers, also known as model numbers, are not random digits. They are packed with meaning. Each digit carries unique and specific information about the watch. Ranging from its model family to its materials and bezel style, every bit is explained. Understanding the Reference Numbers can help you verify the authenticity and date of the watch, as well as estimate its market value.
First Digits – Rolex Model Family
What do the Model Digits reveal? The first few digits of a Rolex Reference Number indicate the watch’s model family. For example, “116” typically points to the iconic Rolex Submariner, while “126” corresponds to a modern Datejust model. This prefix is crucial for identifying the overarching series to which the watch belongs, making it easier to compare various styles within a category.
Following the model family digits, the next numerical position often reveals the material of the case. For instance, a “0” indicates stainless steel, while digits like “3” or “8” signify two-tone gold and steel combinations. Solid gold or platinum models are denoted by different numbers as well, such as “6” for platinum.
The final digit in a Reference Number provides specific information about the bezel style. Giving signs that indicate design variations, including smooth, fluted, or gem-set bezels. By decoding these elements, one gains a deeper understanding of a Rolex watch’s unique attributes and features, uncovering its intricacies and ensuring a more comprehensive evaluation of its craftsmanship and provenance.
The initial digits identify the watch’s family or collection.
Here’s a quick guide to popular model prefixes:
Collection Reference Starts With
- Air-King 55, 140, 116
- Date 15, 150, 115
- Datejust 16, 162, 1162
- Day-Date 65, 18, 180, 182, 183
- Daytona 62, 162, 1165
- Explorer 142, 10, 1142, 2142
- Oyster Perpetual 10, 140, 142, 114
- Milgauss 65, 10, 1164
- Sea-Dweller 16, 166, 1166, 1266
- Submariner 55, 140, 1140
- GMT-Master 65, 16, 1675
- GMT-Master II 167, 1167, 1267
- Yacht-Master 166, 686, 696, 1686
- Sky-Dweller 326
Deciphering the Bezel Code
One digit in the reference number denotes the bezel’s style:
- 0 Smooth, domed, or polished
- 1 Engine-turned
- 2 Engraved
- 3 Fluted
- 4 Bark or hand-crafted
- 6 Rotatable
- 7 Specialty or various (e.g., Explorer II)
Understanding the Material Code
Another digit captures the material of your Rolex case:
- 0 Stainless steel
- 1 Stainless steel & Everose Gold
- 2 Stainless steel & Platinum
- 3 Stainless steel & 18k yellow gold
- 4 Stainless steel & 18k white gold
- 5 Everose
- 6 Platinum
- 8 18k yellow gold
- 9 18k white gold
Why the Reference Number Lengths Vary
Older models offered shorter, four-digit reference numbers that
described the models, size, and movement. Modern watches introduce the concept of more detailed,
six-digit Reference Numbers Greater lengths allow extended specificity as the eminent Rolex catalog continues to evolve.
Rolex Serial Numbers and What They Mean
Every Rolex serial number serves as a unique identifier. While post-2009 serials are randomly generated and do not directly reveal the manufacture year, vintage watches (pre-2010) offer more clues. Here’s a brief look at letter prefixes from the early 2000s and their corresponding years.
Rolex Serial Numbers can prove an invaluable tool for verifying the authenticity and digging deeper to determine the approximate production year of the timepiece, especially suited to Vintage Rolex Collectors. For example, a serial number starting with the letter "P" corresponds to watches manufactured in 2000, while a "K" prefix indicates 2001.
Allowing enthusiasts and collectors to trace the origins of their watches provides a historical context that can enhance the overall appreciation of these timeless pieces. With Rolex transitioning to randomized Serial Numbers in 2010, collectors must rely on other factors, such as paperwork, sales receipts, or service records, to confirm a watch’s age.
First Serial Letter Year
G 2009
V 2008
M 2007
Z 2006
D 2005
F 2004/03
Y 2002
K 2001
Special Historical Note
Across most eras, Rolex never duplicated a Serial Number.
However, in 1954, after reaching 999999, Rolex reset to 010000,
making it possible for two authentic vintage pieces to share the same serial number.
Bracelet Clasp Codes Explained
In addition to the main case, Rolex also has a code inscribed on the back of each bracelet clasp. This “clasp code” shows the manufacture date (month and year) of the bracelet itself. It is not very unusual for the bracelet’s date to differ slightly from the watch. Any changes, however, to the clasp after purchase certainly impact the resale value for collectors.
Interpreting Your Numbers with Confidence
Deciphering these engravings adds an extra dimension to Rolex ownership, whether it's collecting, buying, or selling. Interpreting the numbers with confidence enables you to discern the age of the model, its authenticity, and its style, offering a glimpse into the luxury and legacy of your watch.

How do I find my Rolex numbers?

- Both numbers are also recorded on authentic Rolex documentation (“papers”).
What’s the Reference Number used for?
From revealing your watch’s model to its case material and decoding the bezel type, the Reference Number is used to verify the authenticity of describing its size and movement. For example, Submariners carry references like 140, 1140, or 16610.
A crucial identifier for your Rolex watch, everything, including the design details, is specified, serving as a blueprint for your timepiece. Furthermore, the Reference Number helps determine the exact spare parts needed for repairs or maintenance, ensuring the longevity and value of your Rolex.
What’s the Serial Number used for?
A unique identifier, the production year of your Rolex, and the Serial Number particularly help collectors and enthusiasts determine the watch’s approximate age. Playing a crucial role in verifying the authenticity of a Rolex, these align with your official Rolex records and thus cannot be tampered with. Please note that, depending on the production year, the Serial Number will be either engraved on the case between the lugs or on the rehaut.
