What year is my Rolex?

To determine what year your Rolex watch is, use the serial number. Normally, you will find the number engraved on the bottom half of the back of the case. Depending on the age and model, the serial number ranges from four to eight digits in length. You can contact Rolex to determine the year that corresponds to the serial number or use an online tool.
