Suggestion: In order to avoid placing unnecessary strain on the movement,
the split-seconds hand should not be left in a stopped position for long
periods. It is essentially only used for the measurement of intermediate times
or for recording a second finish time, and should be resynchronized with the
chronograph seconds hand once again after doing so.
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 pro-
vides 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 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 per-
sons, IWC will accept no warranty or liability claims.
Recommendation: Your authorized IWC Official Agent must carry out a
water-resistance test whenever your IWC watch is opened and serviced.
