WAT E R - R E S I S TA 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 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 Inter net 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
unusual ly 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.
