All the parts in this watch are manufactured from top-quality materials.
Nevertheless, a number of parts are subject to natural wear and tear.
It is particularly important to ensure that points at which wear occurs are
always optimally lubricated and that contamination of the oil caused by
metal-to-metal abrasion is regularly removed. This is why we recommend
that you have a maintenance service carried out on your watch about
every five years. Please contact an approved IWC Official Agent or
send your watch directly to the IWC Customer Service Department in
Schaffhausen.
