As a result of the ever greater prevalence in recent years of
very strong magnets made from rare-earth alloys (for example
neodymium-iron-boron) – these are found in objects such as loud-
speakers, jewellery and fasteners on mobile-phone cases and
handbags – mechanical watches are increasingly likely to come
into contact with such magnets and be magnetized. This can lead
to the watch rate being permanently affected, a problem that can
only be resolved by a process of demagnetization carried out by
a specialist. We recommend that you keep your watch away from
such magnets.
Watches with a soft-iron inner case provide a higher level of protec-
tion against magnetic fields and far exceed the requirements of
DIN standard 8309. Nevertheless, it is still possible for the watch
movement to be magnetized in the close proximity of very strong
magnets. We therefore recommend that watches with a soft-
iron inner case also be kept away from direct contact with strong
magnets.
Should there be a sudden change in the precision of your time-
piece, please contact an authorized IWC Official Agent to have
your watch checked for magnetism.
