International Warranty

Longines is delighted you have chosen a timepiece from its collection, which lives up to the brand’s long-established know-how, based on research combined with technical excellence and timeless elegance.

La Compagnie des Montres Longines, Francillon S.A. grants you, with effect from the purchase date, a twenty-four (24) month warranty on all LONGINES® watches models and a five (5) year warranty on the mechanical watches purchased from January 1, 2021, under the terms set out in this warranty. All watches bought form the Collector’s Corner and all watch straps and bracelets are covered by a 24 month international warranty for any material or manufacturing defects.

The Longines international warranty covers defects in materials and manufacturing that exist at the time of delivery of the Longines watch purchased (“defects”). The warranty takes effect only if the warranty certificate has been dated and fully completed by an official Longines dealer (“valid warranty certificate”). During the term of the warranty and on presenting the valid warranty certificate, you are entitled to have any defect repaired free of charge. In the event that repairs cannot restore your Longines watch to full working order, La Compagnie des Montres Longines, Francillon S.A. undertakes to replace it with an identical Longines watch or another Longines watch with similar characteristics.

The warranty for the replacement watch expires on the same date as the warranty for the replaced watch.


The warranty is only valid if the warranty certificate enclosed with your Longines® watch upon purchase is dated, fully and correctly completed and stamped by an official Longines® retailer.

Longines Watch Co. Francillon Ltd, will not accept under warranty any watch which do not match these conditions.
PS: Please read carefully our international guarantee in our instruction for use manual.
