As a result of the ever greater prevalence in recent years of very
strong magnets made from rareearth alloys (e.g. neodymium
ironboron) – these are found in objects such as loudspeakers,
mobile phones and fasteners on jewellery as well as handbags –
mechanical 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 softiron 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 softiron inner case also be kept away from direct contact
with strong magnets.
Should there be a sudden change in the precision of your
timepiece, please contact an authorized IWC Official Agent to
have your watch checked for magnetism.
