Chrono-Automatic Edition TOP GUN
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 impor-
tant 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.
