Check your watch’s serial for signs of a superclone.
Buying pre-owned? Superclones have become hard to spot by eye, but their serials are not random: factories reuse the same patterns across fakes. We monitor the shops that sell them and find those patterns, to help you avoid a counterfeit before you pay.

Why smart buyers check the serial first.
A SerialRisk check is the fastest first step with any pre-owned Rolex. It shows you whether a watch needs a closer look.
Superclones fool the eye
Today’s superclones copy the case, the dial, the weight and even the movement, well enough to fool trained eyes. That is why the serial number has become a signal no inspection should skip.
Counterfeit serials are not random
The factories behind these counterfeits give a whole batch of replicas the same serial pattern. SerialRisk monitors the shops that sell them and uncovers those patterns, so you can buy with more confidence.
Automated check in seconds
Opening a caseback needs a watchmaker, special tools, an appointment and the watch already in your hands. A serial check runs automatically and answers in seconds: before you pay, or at every intake if you are a dealer.
Make serial screening part of every intake.
Screen your whole stock in one go and every incoming watch via API - one more signal for keeping fakes out of your inventory.

Before you pay for a check.
Yes. The exact serial does not have to be in our records for a check to return a signal.
Replica factories reuse structures, character positions and generation rules across production batches. A previously unseen serial that follows one of those structures returns a Pattern signal, and the result shows what matched.
One more check before you buy the watch.
Check the serial against known counterfeit records and recurring pattern signals.
