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. This means your money is safe until you're sure you're satisfied with your purchase. Only then will we transfer payout to the dealer. 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.

If certification is available for a watch, you'll see the green Certified icon in the search results and in the listing. As we are continually adding new watches to our Certified program, it's worth checking your favorite watches for the Certified icon from time to time.

All Certified watches are comprehensively checked against specific criteria by a verified watchmaker. This is how we guarantee the authenticity of your watch.
The check includes the following:
Authenticity check: We check both the exterior and interior of the watch against our definition of authenticity. See also: How do we define authenticity?
Condition check: We check whether the condition of the watch matches the information in the listing, including the complications, winding mechanism, chronograph function, and more. See also: How do we define authenticity?
Scope of delivery check: All additional items, e.g., original box and papers, are checked for completeness and accordance with the model reference.
Stolen watch check: We check whether the watch's serial number is listed in the leading stolen watches databases. This ensures that there are no thefts reported for the serial number.

Every watchmaker who certifies watches under the Certified program has to meet certain criteria. In this way, we ensure he or she has suitable qualifications and technical equipment. Through individualized audits, we also ensure that watches are tested exclusively by experts and in accordance with our standards. If we discover any discrepancies, we hold the watchmakers accountable. See also: What's the difference between Certified Included and Certified Optional?

If you book Certified as an optional add-on, this usually takes an additional 1–3 business days. Watches that already include certification (Certified Included) can be shipped directly to you without delay. See also: What's the difference between Certified Included and Certified Optional?

The certificate of authenticity is a digital document that cannot be lost, stolen, or damaged. Once you've received the watch, you can find the corresponding certificate in your Chrono24 account. After logging in, you can access it under the "Buy" menu or directly via your Watch Collection.

If Certified is included in your purchase, certification has already taken place and the condition of the watch will match the information in the listing.
If you booked Certified as an add-on, our in-house watchmakers will carry out a thorough check. If they notice the condition of the watch differs from the information in the listing (e.g., additional scratches) or that key replacement parts without a brand name or logo are present (e.g., different bracelet or hands), they will reach out to you.
You typically have three options of how to proceed:
You accept the results of the certification and decide to proceed with buying the watch. In this case, your watch should be ready for dispatch and shipped to you within 1–3 business days.
You decide to withdraw from the purchase due to the discrepancies found. In this case, we'll ship the watch back to the seller and refund you your payment from our escrow account.
At your request, we can contact the seller and suggest adjusting the purchase price. If you agree to a lower price, we'll send you a partial refund from our escrow account after the watch has been delivered.

Returns under the Certified program are subject to our general returns policy. If you buy from a professional dealer, you can exercise your statutory right to withdrawal within 14 days of receiving the watch and get your money back quickly and hassle-free.
Private sellers are not legally mandated to accept returns.

No. Certification is not mandatory if you want to buy a watch on Chrono24. However, if Certified is already included for a particular watch, this service cannot be withdrawn or modified. There are a variety of watches that come with the option of booking Certified as an add-on during the purchase process.

The certificate of authenticity contains information about the make and model of the watch as well as its date of issue. The watch's serial number, production year, and reference number, as well as the Chrono24 transaction (TC) number are included on the certificate. If, during the certification process, the watchmaker notices any deviations from the original in terms of authenticity or replacement parts, these will be listed as additional comments. Only you have access to your digital certificate of authenticity. You can access it in your Chrono24 account.

Together with your Certified watch, you will receive a digital Certificate of Authenticity that includes an Authenticity Guarantee. This guarantee conforms to our definition of authenticity and is valid for one year from the date the certificate is issued. If you suspect that your watch does not meet our definition of authenticity, please contact our support team and they will review your request immediately. Depending on the outcome of this review, we will either reimburse you for the full purchase amount or replace the component in question so that the watch fully meets our definition of authenticity.
