– Setting the watch back another 12 hours the following morning between 2 a.m. and 11 a.m. will
synchronize the date display with the local date.
INFORMATION ABOUT MAGNETIC FIELDS
As a result of the ever greater prevalence in recent years of very strong magnets made from rare-earth
alloys (e.g. neodymium-iron-boron) – these are found in objects such as loudspeakers and mobile
phones and fasteners on jewellery as well as handbags – mechanical watches are increasingly likely to
come into contact with such magnets and become magnetized. This can lead to the watch rate being
permanently affected, a problem that can only be resolved by a process of demagnetization carried
out by a specialist. We recommend that you keep your watch away from such magnets.
Watches with a soft-iron inner case provide a higher level of protection against magnetic fields and far
exceed the requirements of DIN standard 8309. Nevertheless, it is still possible for the watch move-
ment to become magnetized in close proximity to very strong magnets. We therefore recommend
that watches with a soft-iron inner case also be kept away from direct contact with strong magnets.
Should there be a sudden change in the precision of your timepiece, please contact an authorized
IWC Official Agent to have your watch checked for magnetism.

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 un usually 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.
