WATER- RESISTANCE
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 Internet 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 stays properly water-resistant, 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 un authorized
persons, IWC will accept no warranty or liability claims.
Recommendation: Your authorized IWC Official Agent must carry out a water-resistance test when-
ever your IWC watch is opened and serviced.
