Certificates of authenticity


Every Longines watch made since 1867 has been meticulously issued with a serial number. Based on these records, Longines can offer a service acclaimed by devotees of the brand all over the world. We can issue an excerpt of a watch record from our Archives once we are provided with some good quality photographs and the serial number of the watch.
We can also issue a Certificate of Authenticity signed by the company president. Please note that the watch must be shipped to us for authentication by one of our watchmakers before we can issue the Certificate. These documents display the information from the record in the Longines archives pertaining to each timepiece. Both of these services are offered free of charge, however shipping costs and import duties linked to the sending of a watch for authentication are at customer’s charge.

Should you wish to obtain either of these documents, please contact Longines via the " Contact Us " form on the website www.longines.com. Select the reason for contacting us as follows: "Historical information on a Longines watch". Complete all fields and indicate the subject of your request.
