Resistance to magnetic fieldsUpdated 25 days ago

All SERICA watches offer protection against everyday magnetic fields. However, the Ref. 5303 provides a superior level of resistance thanks to a soft iron inner cage, allowing it to withstand magnetic fields stronger than 50,000 A/m. This makes it a particularly reliable tool in demanding environments.

Other references in the SERICA collection, although not equipped with this cage, are still designed to resist common magnetic fields encountered in daily life (electronic devices, bags with magnetic clasps, etc.).

To avoid in all cases:

• Prolonged contact with powerful magnetic sources (speakers, electric motors, industrial equipment).
• Repeated exposure to intense fields, such as those generated by industrial scanners or MRI machines.

A strong magnetic field can affect the accuracy of a mechanical movement. If in doubt or in case of unusual behavior (sudden gain or loss of time), our customer service is available to perform a quick and risk-free demagnetization of your watch.
