Certified is our new certification service whereby verified watchmakers check and certify the authenticity of watches to provide customers on our marketplace with a worry-free buying experience.

1. Look for listings with the Certified icon
Certified watches can be identified by the green "C" icon in the search results and in the listing. You can also filter search results to only view Certified watches. On the listing page, you can see whether Certified is already included or whether it's an optional add-on to your purchase.

2. Certification by verified watchmakers
Before you receive your watch, it will be checked and certified by a verified watchmaker. Among other things, the watchmaker checks whether your watch matches the listing information and whether it complies with our definition of authenticity.
3. Receive your watch and digital certificate of authenticity
After successful certification, you can rest assured your new watch is genuine. This is confirmed by a certificate of authenticity, which you can access digitally after receiving your watch.

Chrono24 Buyer Protection offers complete security for your payment. If you purchase from a professional dealer, we will hold the purchase amount in our escrow account for 14 days after you receive your watch.

If you aren't satisfied with your purchase, you can exercise your statutory right to withdraw and return the watch to the dealer within 14 days for any reason.
If you purchase from a private seller, we will hold the purchase amount in our escrow account for 7 days after you receive your watch. Please note, however, that private sellers are not legally mandated to accept returns.
