INFORMATION ABOUT MAGNETIC FIELDS
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 and 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 soft-iron inner case provide a higher level of protection against magnetic fields and far
exceed the requirements of DIN standard 8309. Nevertheless, it is still possible for the watch move-
ment 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 timepiece, please contact an authorized
IWC Official Agent to have your watch checked for magnetism.
