To ensure that your watch continues to function perfect-
ly, 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 persons, IWC will accept no
warranty or liability claims.
Recommendation: Your authorised IWC Official Agent
must carry out a water-resistance test whenever your
IWC watch is opened and serviced.
Servicing your Ingenieur Chronograph
Although the parts in this watch are all manufactured
from top-quality materials, a number of components are
subject to natural wear and tear. It is particularly impor-
tant to ensure that the points at which wear occurs are
always well-lubricated and that oil contaminated by
metal abrasion is regularly removed. For this reason, we
recommend that you have your watch serviced approxi-
mately every five years. Please contact an authorised
IWC Official Agent or send your watch directly to the
IWC Customer Service Department in Schaffhausen.
