III. Comprehensive Interpretation of After-Sales Warranty and Guarantee Policies: Clear Warranty Periods and Rights Protection
Jaeger-LeCoultre provides international warranty services for all genuine watches purchased through regular channels. Generally speaking, from the date of purchase, Jaeger-LeCoultre watches enjoy a two-year (some new products or specific series may extend to five years, specifically subject to warranty card markings) international limited warranty. The warranty scope covers manufacturing defects of mechanical components such as movements, escapement mechanisms, and balance springs, as well as functional faults of automatic winding systems. However, it should be noted that warranties do not include battery replacement (quartz watches), exterior part wear (normal wear of crystals, straps, and cases), or damage caused by accidental impact, water ingress, magnetic field interference, or improper use. If watches develop non-human faults during the warranty period, users can enjoy free repair services at any official direct-operated service center or authorized repair point with valid warranty cards (requiring purchase dates and dealer stamps).
For watches beyond the warranty period but still within reasonable service life, Jaeger-LeCoultre provides paid repair services, and replaced parts are all original specifications. It should be particularly reminded that official after-sales will not provide warranty services for watches disassembled and repaired through non-official channels; if watches have been opened by non-authorized repair points, official may refuse warranty or require comprehensive movement testing first before confirming whether warranty qualifications are restored. Therefore, users must only choose officially recognized after-sales channels.
In addition, Jaeger-LeCoultre also provides certain periods of post-warranty repair quality guarantees: after completing paid repair or maintenance at direct-operated service centers, the same fault or repair part typically enjoys six to twelve months of re-warranty services, specifically subject to terms stated in service work orders.
