Servicing your Portuguese Perpetual Calendar 24 | 25
Although the parts in this watch are all manufactured from top-quality ma-
terials, 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 regu-
larly 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.
Effective from February 2010.
