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 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.

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 indica
tion as to actual use of the watch in the presence of moisture
and wetness, and in or under water. Recommendations for use
in connection 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 stays properly waterresistant, you
should have it checked by an IWC service centre at least once
a year. Your watch should also be tested after exposure to
un usually harsh conditions. If the tests are not carried out as
stipulated, or if the watch is opened by unauthorized persons,
IWC will accept 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.

If your watch has a strap made of leather, textile or rubber with
a leather or textile inlay, make sure that the highquality strap
does not come into contact with water, oily substances, solvents,
cleaning agents or cosmetic products. This way you can prevent
discoloration and premature ageing of the material.
