SERVICING YOUR
PILOT'S WATCH PERPETUAL CALENDAR CHRONOGR APH
Although the parts in this watch are all manufactured from top-quality materials, a number of compo-
nents 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
5 years. Please contact an authorized IWC Official Agent.
