Location of the Serial Number: On most Rolex watches, the serial number is engraved between the lugs at the 6 o’clock position. You’ll need to remove the bracelet to see it. Newer models (post-2005) have the serial number engraved on the rehaut (the inner bezel) for easier visibility.

Decoding the Serial Number: Rolex serial numbers are alphanumeric and can indicate the production year of the watch. For example, serial numbers starting with “G” were produced in 2010, while those starting with “2” were made in 2021. Online databases and Rolex experts can help decode these numbers.

Verifying Authenticity: The serial number is a key tool in verifying a Rolex’s authenticity. Counterfeit watches often have poorly engraved or incorrect serial numbers. Always cross-check the serial number with Rolex records or consult an authorized dealer.

Rolex Model Number: In addition to the serial number, Rolex watches have a model number (also called a reference number) engraved between the lugs at the 12 o’clock position. This number identifies the specific model and its features.

Importance for Buyers: When purchasing a Rolex, always verify the serial and model numbers. This ensures you’re getting a genuine timepiece and helps you understand its history and value.
