The water-resistance of IWC watches is stated in bar and not in metres. Metres, which
are often used elsewhere in the watch industry to indicate water-resistance, cannot
be equated with dive depth because of the test procedures that are frequently used.
Water-resistance shown in metres provides no indication 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 water-resistance of your watch can be found on the Inter-
net at www.iwc.com/water-resistance. 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 unusually 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 water-resist-
ance test whenever your IWC watch is opened and serviced.
