ROLEX CODES YEARS CLASPS

Rolex Clasp Codes :

On the inside of the clasp hinge is a code that designates the month and year that the clasp/bracelet was manufactured.

When examing watches at an AD or watch mart, do not be surprised if a bracelet is a few years older than the watch case. In modern Rolex watches, it is rare to find a clasp code that is the same year as the watch case.

On the clasp hinge is one two letters followed by a number.

The letters represent the year code, and the numbers signify the month.

A clasp code of OP9 indicates the clasp/bracelet was manufactured in 2006, and the number indicates the month of September.
