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 unusual ly harsh conditions. If the tests are not carried out as
stipu lated, 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.
N O T E
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.
