Watch Authenticity
How can I ensure the authenticity of a timepiece?
To determine whether or not your watch is authentic, please contact an official Patek Philippe retailer. If you are unable to provide the case and movement numbers thanks to a Certificate of Origin or an Extract from the Archives, you may need to remove the case back of the watch to find out the number, a delicate intervention that can only be carried out by an Authorized Retailer or an Authorized Service Center.
What is the current resale value of my timepiece?
Patek Philippe cannot provide information of this kind. We recomment that you contact an auction house or a dealer specialized in selling and buying older timepieces.
Where can I find the movement and case numbers?
The case back of your timepiece must be removed to see the movement number. The movement number is engraved in the movement of your watch. The case number is engraved on the inside of the case back. The removal of the case back of a wristwatch or pocket watch should only be performed by an Authorized Retailer or an Authorized Service Center.
How can I replace a lost Certificate of Origin?
The Certificate of Origin can unfortunately never be re-issued. Please contact your Official Patek Philippe Retailer from whom you purchased your timepiece for assistance.
