Rolex has been engraving their watches with a unique number since the early 1020’s. You can use this number as a tool in order to identify the production year of your watch. This number can be located by removing the bracelet with a small screw driver or spring bar tool, and looking at the case of the watch between the lugs, just below the 6 o’clock end of the watch. It is a five to seven digit number.
The chart below can be used as a reference:
|ROLEX SERIAL NUMBER||PRODUCTION YEAR|
|CLASP CODE: LT||2009|
|CLASP CODE: E6R, R5||2010|
