well as handbags – mechanical watches are increasingly likely
to come into contact with such magnets and become mag­
netized. 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 pos­
sible 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.
WATER-RESISTANCE
The water­resistance of IWC watches is stated in bar and not in
metres. Metres, which are often used elsewhere in the watch
industry to indicate water­resistance, cannot be equated with
