Rolex Reference Numbers: Ultimate Guide

What kind of Rolex do you have? What is it made of? When was it manufactured? All of these answers, along with a variety of other information, is etched into your watch, via the reference number, the serial number, and the clasp code. If you know what to look for, you can tell a lot about your watch, just by looking at those numbers. Or if you want to know more about your Rolex, you can use those numbers to look up the information you need. Here’s your ultimate guide to Rolex reference numbers, serial numbers, and clasp codes…

What Do The Reference Numbers Mean?

The reference number is located on the watch case, between the lugs, right above the 12. Watches made before the late 70s will have 4-digit reference numbers. If your watch was made in the 80s or 90s, it will most likely have a 5-digit reference number. If it was produced since 2000, it will most likely have a 6-digit reference number, often beginning with 1.

The Beginning Numbers

The first few (between two and four) digits of the reference number tells you the watch model: Day-date, Datejust, Daytona, Submariner, etc. The next digit after the model is the Bezel Code. If you want to find this number at a glance, it should be the second to last digit in the reference number. The bezel is the ring that holds the watch crystal in place. The Bezel Code tells you the style of bezel you have. Note that only Rolex dress watches have Bezel Codes. Sports watches do not.

The End Numbers

The final digit in the reference number is the Material Code, which tells you what type of material your watch is made of. Note that if your reference number only has four digits, there is no material code. However, if it has five or six digits, the material code is the last number in the sequence.

The Letters

Some reference numbers are also followed by a string of letters—either two or four. These represent either the color of the bezel or the gems that it uses. Now that we’ve covered the basics, here’s your guide to the reference numbers of Rolexes.

RBOWRainbow Sapphires
GVGlace Verte (Green Crystal)

In addition to the serial number on the watch itself, many Rolexes have identifying numbers on the watch clasp, to let you know the year and month it was manufactured. As with the serial numbers, clasp numbers since 2011 have been randomized, but can be looked up online. For watches manufactured in 2010 or before, however, the letter
code represents the year, and the first number represents the month. So a watch clasp manufactured in February of 2010 would begin with RS2 – RS being the clasp code for 2010, and 2 representing February. Here are the clasp letter codes you need to know:

Country Codes

Finally, let’s talk about the country codes. These are a three-digit code that tell you where your Rolex was manufactured. It’s not on the watch itself, but if you still have the Guaranty Certificate, it should be in the upper left corner. Note that only watches manufactured since 1980 have country codes.
