If you own a Rolex or are planning to buy one, understanding the significance of the watch’s reference and serial number is crucial. These numbers are not just random digits — they are the key to unlocking vital information about your timepiece, including its model, production year, and most importantly, its authenticity.
Whether you're a new collector, a seasoned enthusiast, or simply verifying your watch before resale or servicing, learning where to locate these numbers can save you time and money.
In this guide, we’ll walk you through how to easily find both the reference and serial number on your Rolex watch.
Where Can I Find the Reference and Serial Number on My Rolex Watch?
If you have an older Rolex (made before 2005), the reference number and serial number are engraved between the lugs — these are the parts of the case where the bracelet or strap connects. You’ll find the reference number at the top (12 o'clock side) and the serial number at the bottom (6 o'clock side). To see them, the bracelet needs to be carefully removed, which should only be done by a professional to avoid damage.
For newer Rolex watches made after 2008, locating the serial number is a breeze. It’s engraved on the inner bezel — the ring inside the watch face — near the 6 o’clock position. The reference number is still located at the 12 o'clock position between the lugs. This makes the process of identifying your Rolex much simpler and more accessible.
If you have the original paperwork or warranty card that came with your Rolex, both numbers will be listed there. This is the easiest and safest way to check them.
It's important to note that removing parts of your watch yourself can lead to scratches or damage. If you're unsure, it's always best to visit a trusted expert like LXY Philly.
These numbers are crucial — they help verify your Rolex’s model, age, and authenticity, which is especially useful for collectors or anyone looking to sell or service their watch. Professional guidance ensures the safety and integrity of your timepiece.
Rolex Watches Made Before 2005
If your Rolex was made before 2005, you’ll find the reference and serial numbers engraved between the lugs — the small arms on the watch case where the bracelet or strap connects. To view these numbers, the bracelet must be carefully removed. The reference number (which tells you the model) is engraved near the 12 o’clock side, and the serial number (which is unique to your watch) is located near the 6 o’clock side. Because this process requires precision, it’s best to have a trained watchmaker do it to avoid scratching or damaging your Rolex.
Rolex Watches Made After 2005
For watches made after 2005, things are easier. The reference and serial numbers are usually listed on the original warranty card or paperwork. If you still have the documents, there’s no need to take the watch apart. But if you don’t have the papers, you can still find the serial number engraved on the inner bezel (the ring inside the dial) at the 6 o’clock position. The reference number is still between the lugs at 12 o’clock and requires bracelet removal.
These numbers are important — they help confirm that your Rolex is genuine, determine when it was made, and make sure any service or repair uses the correct parts. Always consult a trusted watch expert if you need help finding them.
What Can the Reference Number Tell You About Your Rolex?
The reference number on a Rolex isn’t just a random set of digits — it actually gives you useful information about the watch.
-
The first few numbers usually tell you the model or type of Rolex you have, like a Submariner, Datejust, or Daytona.
-
The second-to-last number often shows the style of the bezel, such as whether it’s fluted, smooth, rotating, or engine-turned.
-
The last number usually reveals the material used for the case — whether it’s stainless steel, gold, two-tone, or platinum.
Keep in mind that this is a general guide. Some models and production years may have slight differences or exceptions in how these numbers are used. Rolex has made updates and changes over time, so the meaning of the digits can vary depending on the era and specific watch model.
