Water-resistance
The water-resistance of IWC watches is stated in bar and not in metres. Me-
tres, 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 authorised 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 unauthorised per-
sons, IWC will accept no warranty or liability claims.
Recommendation: Your authorised IWC Official Agent must carry out a wa-
ter-resistance test whenever your IWC watch is opened and serviced.
Servicing your Da Vinci Chronograph Ceramic
Although the parts in this watch are all manufactured from top-quality mate-
rials, a number of components are subject to natural wear and tear. It is par-
ticularly important to ensure that the points at which wear occurs are always
well-lubricated and that oil contaminated by metal abrasion is regularly re-
moved. For this reason, we recommend that you have your watch serviced
approximately every five years. Please contact an authorised IWC Official
Agent or send your watch directly to the IWC Customer Service Department
in Schaffhausen.
