To ensure that your watch stays prop­
erly 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.
