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 movement to be mag-
netized in the close proximity of very
strong magnets. We therefore recom-
mend 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.
INFORMATION ABOUT
MAGNETIC FIELDS
As a result of the ever greater prev-
alence 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 increas-
ingly 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 spe-
cialist. We recommend that you keep
your watch away from such magnets.
