As a result of the ever greater prevalence in recent years of very
strong magnets made from rare-earth alloys (e.g. neodymium-iron-
boron) – these are found in objects such as loudspeakers, jewellery
and fasteners on mobile-phone cases and handbags – mechan-
ical watches are increasingly likely to come into contact with such
magnets and become 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
protection against magnetic fields and far exceed the require-
ments of DIN standard 8309. Nevertheless, it is still possible for
the watch movement to become magnetized in close proximity to
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.
