Quartz movement:

The energy for a quartz watch is supplied by a battery that lasts for several years. The battery supplies energy to the quartz, which measures time. The average battery life for J12 quartz watches is two to four years depending on the model, and two years for other collections.

Never leave an expired battery in your watch, as it could leak and damage the movement.

Self-winding mechanical movement:

A Self-winding, or Automatic movement has a rotor activated by gravity as the wrist moves around to keep the movement wound.  A fully wound movement has an approximate 42 hour power reserve and will run most accurately.  If the movement has come to a full stop wind the watch before wearing.  It is recommended to wind a watch weekly.

For optimal precision and reliability, we recommend that you avoid:

• Magnetic fields (magnets, loudspeakers, tablets, smartphones, etc.);
• High impacts (sports requiring sudden movements such as tennis or golf).

The watch must be perfectly adjusted to your wrist. A poorly fitting bracelet results in the loss of the watch’s autonomy (self-winding capacity).
