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 nat-
ural 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 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 Department in Schaffhausen.
