When and how should the battery be changed?

The average lifespan of a battery is two years for both desk clocks and travel clocks.

We advise you not to leave an old battery inside your clock, since its deterioration may damage the movement.

To change a battery, entrust your clock to a Cartier boutique or authorized retailer.
