As a result of the ever greater prevalence in recent years of very
strong magnets made from rare­earth alloys (for example neo­
dymium­iron­boron) – these are found in objects such as loud­
speakers, jewellery and fasteners on mobile­phone 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 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 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
soft­iron 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.

WAT E R - R E S I STA N C E
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 dive
depth because of the test procedures that are frequently used.
Water­resistance shown in metres provides no indication as to
actual use of the watch in the presence of moisture and wet­
ness, and in or under water. Recommendations for use in connec­
tion with the water­resistance of your watch can be found on the
Internet at www.iwc.com/water­resistance. Your authorized IWC
Official Agent will also be pleased to provide you with information.
To ensure that your watch continues to function perfectly, you
should have it checked by an IWC service centre at least once a
year. Your watch should also be tested after exposure to unusu­
ally harsh conditions. If the tests are not carried out as stipulated,
or if the watch is opened by unauthorized persons, IWC will ac­
cept no warranty or liability claims.
Recommendation: Your authorized IWC Official Agent must carry
out a water­resistance test whenever your IWC watch is opened
and serviced.
