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
loudspeakers, 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 car-
ried 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 pro-
tection 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.
