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 authorized dealer's.
