What is Authenticity Guarantee for Watches?

eBay’s Authenticity Guarantee is a service designed to help buyers shop with confidence. Our third-party authenticators physically inspect all eligible items before they are shipped to the buyer.

How does Authenticity Guarantee work?

It’s easy! Browse and shop eBay’s listings with the “Authenticity Guarantee” badge. When you buy an eligible item, the seller sends the item directly to a third-party authenticator. The authenticator will thoroughly inspect and verify your item’s authenticity before it is shipped to you safely via two-day shipping with a signature required paid for by eBay! 

Will I be charged a fee for Authenticity Guarantee?

No. Through the Authenticity Guarantee service, eBay covers the cost of authentication, as well as two-day, secure shipping from the third-party authenticator facility to the buyer.

What items are “eligible” for Authenticity Guarantee? 

Currently, watches listed in the primary category of wristwatches and sold for $2,000.00 USD or more are eligible for the Authenticity Guarantee service. In addition, Auction items in the wristwatch category that are expected to sell above $2,000.00 USD are also included in the service. 

Smart watches, watch parts, and accessories are not eligible for authentication. Items specified as customized will not be authenticated. Customized is defined as original brand parts that have been replaced with non-brand parts, or parts not original to the model or era, or components that are modified from the original design. Listings that offer only local pickup or items shipped to P.O. Boxes will not be eligible for Authenticity Guarantee. Any item purchased using an offline payment method will not be eligible for Authenticity Guarantee. 

Only items purchased on are eligible for Authenticity Guarantee. Items that are listed on from select sellers located in Japan, United Kingdom, and Germany for delivery to a buyer located within the US are eligible for Authenticity Guarantee provided that items comply with international import laws including CITES - check back for additional countries to be added. However, items that ship to a buyer address outside the continental U.S. are not eligible for the service.

Listings that offer only local pickup or items shipped to P.O. Boxes will not be eligible for Authenticity Guarantee.

Are vintage watches eligible for Authenticity Guarantee?

A vintage watch is eligible for the Authenticity Guarantee service, if all eligibility criteria are met. Vintage watches which are verified as authentic by the third-party authentication partner may contain replacement parts that are not from the original manufacturer if the original manufacturer no longer makes that part. 

Vintage timepieces and many used watches may not be water resistant to their original rating. Please consult a watchmaker before exposing your watch to water. Mechanical watches are more delicate than other types of watches. Take care before undertaking any activity which might place shock on the watch.

What happens at the authenticator?

After the eBay authentication partner receives the watch, the authentication partner first confirms the item and collateral materials are consistent with the listing title, description, and images. Then they will perform a multi-point physical authentication inspection. Finally, a security tag will be attached to the watch.

The eBay authentication partner does not verify the timekeeping accuracy of your watch. Vintage and many used watches may require servicing by an experienced watchmaker to restore accurate timekeeping. If you have any questions about the functions or warranty of your watch, please refer to the seller’s description. The Authenticity Guarantee does not offer a warranty.

Who is providing the authentication services?

eBay has partnered with leading industry experts whose services and capabilities have been thoroughly vetted. The authentication partners are leaders in their industry, with years of experience, brand certified watchmakers and technicians, using advanced technical equipment in a state-of-the-art facility.

How long will the authentication process take? How long until I get my item?

After you purchase your eligible item, the seller is required to send the item to eBay’s third-party authentication partner, who will process your item within two business days of receipt. Once authenticity is verified, the item will be shipped to you with two-day secure delivery including signature confirmation.

How do I track the status of my item?

The order status will be updated in your “My eBay” purchase history and in the View Order Details section. The shipping status can be seen on My eBay Purchase History. The authentication status can be seen on View Order Details. You will also receive an order update email when your item was inspected by our third-party authentication partner as part of the Authenticity Guarantee service.

Will I receive the original packaging with my purchase?

Yes, if the seller has included original packaging as described in the listing, all components will be sent to you.

What if the item does not pass inspection?

If the item’s authenticity cannot be verified or the item’s condition is not consistent with its listing, it will be returned to the seller, and the buyer will be issued a full refund to their original payment method.

Can I return items purchased with Authenticity Guarantee? 

Buyers can return an item if the Seller accepts returns, as stated in the listing, and the return takes place within the Seller’s return window. If the Seller does not accept returns or the return is submitted outside the return window, this will be considered final sale and cannot be returned. 

What is Final Sale?

For Watches that are eligible for Authenticity Guarantee, an item is considered Final Sale when:

  • Item is not eligible for escrow as a payment method.
  • Item condition is “New with tags” or “New without tags.”
  • Seller return policy for the item is “No returns,” or the item’s return window has closed.

Once an eligible item passes authentication through Authenticity Guarantee, sellers have completed their obligation to the buyer for that transaction and that item cannot be returned.

Transactions that meet this criteria are exempt from Significantly Not as Described (SNAD) claims under eBay’s Money Back Guarantee policy.

Will imported items going through Authenticity Guarantee be subject to Duties and Taxes?

International shipment of items may be subject to customs processing and additional charges.

My item was sent back to the seller because it wouldn’t clear customs. What do I do now?

If your item is returned, the seller should work with the carrier and/or broker selected when originally exported the item to the US.

Sellers declare the item’s customs value and must comply with customs declaration laws.

Buyers should be aware of possible: delays from customs inspection, import duties and taxes which buyers must pay and brokerage fees payable at the point of delivery.

Are authenticated items protected by the eBay Money Back Guarantee? 

For authenticated items, eBay Money Back Guarantee only covers items returned within the seller’s return window and items that satisfy the eBay Money Back Guarantee eligibility requirements and are not received or that arrive damaged.

How does the return process work?

If returns are offered on the listing of the item you purchased, the item will first be sent to eBay’s authentication partner. Within two business days of receiving the item, the authenticator will inspect to confirm that the item returned matches the item originally sent to you by verifying the authenticity and condition. In addition, the security tag must be attached to the item and untampered to be eligible for a return. Once verified by the authentication partner, it will be shipped to the Seller and a refund will be processed. The seller or buyer (as defined by the listing) is responsible for shipping costs to the authenticator, and eBay covers the shipping cost to the Seller.

Why was the item sent back to me by the authenticator after I opened a return?

If the third-party authenticator determines the returned item is not the same item, is not in the same condition, or the security tag has been tampered with or removed, it will be sent back to the buyer.

Is there an authentication card? 

Yes, all items verified as authentic come with a card which provides details about the item such as brand, model, reference number, movement type, case material, bracelet type, and serial number, as applicable. 

Can I choose to not have my item authenticated?
