iwc AQUATIMER CHRONOGRAPH Bedienungsanleitung Seite 30

Servicing your Aquatimer 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.
