Rolex watches are among the most prestigious and sought-after timepieces in the world. Whether purchasing new or pre-owned, buyers often have questions about authenticity and production details. At Miltons Diamonds, we specialize in offering high-quality pre-owned Rolex watches, each with a unique serial number that helps verify its history.
This guide explains the purpose of Rolex serial numbers, where to find them, and how to interpret them—along with tips for selling your pre-owned Rolex.
How to Locate a Rolex Serial Number
To check your Rolex’s serial number, look between the watch casing lugs at the 6 o’clock position. The number is typically engraved and ranges from four to eight digits.
In 2005, Rolex changed the placement of the serial number, moving it to the inner rim (or “rehaut”) of the watch. This adjustment was designed to make counterfeiting more difficult.
Before 2010, serial numbers followed a sequential system, making it easy to determine the production year. However, Rolex later switched to randomized numbering, complicating year identification for watches made after late 2010. In such cases, verifying the watch’s original paperwork is the most reliable method.
Decoding Rolex Serial and Model Numbers
Each Rolex serial number is unique, with some indicating the watch’s production year. While older models can be dated using the serial number, post-2010 Rolex watches require additional documentation for precise verification.
Rolex Model Numbers
Model numbers are found between the casing lugs at the 12 o’clock position. These codes, typically four to six digits long, provide details about the watch type and design.
- The first two to four digits indicate the watch model.
- For five- or six-digit codes, the second-to-last digit often describes the bezel type.
- Some models include letters after the numbers, offering further specifications.
