Rolex Counterfeit Serial Number Check

Counterfeit Rolex watches tend to carry the same numbering again and again. Enter a serial number, and the clasp code if you have it, to see whether they fit the numbering our team has recorded on counterfeit watches.

How to read the result

Result What it means What to do next
Strong match The serial number and the clasp code together fit numbering we have recorded on counterfeit watches. This is a serious warning sign, though not proof on its own. Do not buy or sell the watch until it has been inspected in person.
Possible match The serial number fits numbering we have recorded on counterfeit watches. A small number of genuine watches fit by chance, so this is a warning sign, not proof. Add the clasp code if you left it out, and have the watch inspected before you buy or sell.
No match The serial number does not fit our records. Our records cover only some of the counterfeits in circulation, so this does not confirm the watch is genuine. Work through the other checks in our guide on how to spot a fake Rolex.

Where to find the numbers

  • Serial number. On watches made from about 2011, it is 8 letters and digits engraved on the inner ring around the dial at 6 o'clock. See the Rolex serial number chart for where to look on older watches and how to date them.
  • Clasp code. Stamped inside the clasp, close to the hinge. See the Rolex clasp code chart.

What this check can and cannot tell you

  • It compares numbers with our records. It does not examine the watch, and a result is never proof either way.
  • It covers 8-character serial numbers. Older watches with shorter serial numbers are outside its scope. Send us the number and we will look into it.
  • The serial number comes first. A clasp code is checked only together with a serial number, because a clasp code on its own says very little.
  • Our records are private. We do not publish the numbering we hold, because that would help counterfeiters avoid it.
  • Checks are recorded. We keep a record of the numbers entered so we can spot patterns and improve our records.

The only dependable way to authenticate a Rolex is a physical inspection. Every watch sold by Crescent Watch Guys is inspected and guaranteed authentic. If you have a watch you are unsure about, contact our Houston team.
