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
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 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.

The optimal service cycle for your IWC timepiece is exclusive to
your watch and
necessary interval between services will be determined by your
individual wearing habits; frequency of wear, your environment/
s, and the intensity of physical activity you engage in. Your fine
mechanical timepiece is an extension of yourself and will run well
for as long and smoothly as it is treated. Therefore, we simply
recommend you to continue wearing your watch for as long as
pleases you and to only entrust it for a service if you notice a
deviation from the regular performance, function or timekeeping.
It will then be our pleasure to reinstate the premium performance
with the suitable service.
