Although the parts in this watch are all manufactured from top­quality materials, a
number of components are subject to natural wear and tear. It is particularly important
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 approximately every five years. Please contact
an authorized IWC Official Agent or send your watch directly to the IWC Customer
Service Department in Schaffhausen.
