When and how should the battery be changed?

The average lifespan of a battery is two years for both desk clocks and travel clocks. However, excessive use of the hour-striking function may shorten this average lifespan.

We advise you never to leave a used battery inside your clock, since its deterioration may lead to the deterioration of the whole movement.

To change a battery, please contact a Cartier After-Sales Service at any Cartier boutique or at an authorised dealer.
