Jaeger-LeCoultre Customer Service

A Jaeger-LeCoultre timepiece is a high-precision instrument that operates 24 
hours a day, or 8,760 hours a year. It is therefore essential to have it serviced 
once every three years in order to guarantee its good working order and its 
durability. If signifi cant variations occur in the settings, it may be necessary to have 
the movement serviced.

It is also necessary to have the water-resistance of the watch checked once 
every two years, or prior to any period during which it will be subjected to 
prolonged and/or regular immersion.

Maintenance and repair work must be entrusted to an authorised Jaeger-
LeCoultre retailer, or to a Jaeger-LeCoultre Boutique or authorised Jaeger-
LeCoultre Service Centre. The list of our points of sale and service centres is 
available on our website: www.jaeger-lecoultre.com.  You will also fi nd this infor-
mation at the end of this document, under the heading “Where to entrust my 
timepiece for maintenance?”

Our authorised Service Centres are staffed by watchmakers trained at the 
Jaeger-LeCoultre Manufacture, and have the workshops, tools and parts required 
for the repair and maintenance of Jaeger-LeCoultre watches and clocks.

In certain cases, especially for operations requiring special tools and parts, the 
Service Centres will send your watch to the Jaeger-LeCoultre Manufacture in 
Switzerland to have the necessary work carried out.
