WHEN AND HOW SHOULD THE BATTERY BE CHANGED?
The average lifespan of your battery is between two and three years.
We advise you never to leave a used battery inside your watch, since its deterioration may lead to the deterioration of the whole movement.
To change a battery, entrust your watch to a Cartier After-Sales Service at any Cartier boutique or at an authorized dealer's.
As part of the battery changing service, and as required by the Cartier warranty whenever a watch is opened, the Cartier technician will also test the water-resistance of your watch.
