If your watch has a strap made of leather, textile or rubber with
a leather or textile inlay, make sure that the high-quality strap
does not come into contact with water, oily substances, solvents,
cleaning agents or cosmetic products. This way you can prevent
discoloration and premature ageing of the material.

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 important to ensure that the points
at which wear occurs are always well lubricated and that oil con-
taminated 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
or send your watch directly to the IWC Customer Service Depart-
ment in Schaffhausen.
