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.
