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, take your watch to a Cartier After-Sales Service at any Cartier boutique or at an authorised dealer.

As part of the battery changing service, and as required by the Cartier guarantee whenever a watch is opened, the Cartier technician will also test the water-resistance of your watch.
