IWC Schaffhausen BIG PILOT’S WATCH PERPETUAL CALENDAR Instrucciones De Operación página 19

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.
The patina which develops over time protects the metal. It is caused by oxidation, and is similar to the
tarnish which can be seen on items made of silver. The environment to which the metal is exposed
and how often it is used affects how quickly the metal darkens. This is a natural process influenced
by skin contact, humidity, exposure to the elements, etc.
– The surface will not darken uniformly; darker areas and blemishes may develop.
– Bronze is a traditional material which is not as resistant to corrosion as those often used in the
watchmaking industry such as stainless steel, titanium, gold and platinum.
– Skin contact will cause bronze to develop a typical metallic odour when worn (similar to that of
coins).

NOTE SERVICING YOUR
BIG PILOT'S WATCH PERPETUAL CALENDAR
Although the parts in this watch are all manufactured from top-quality materials, a number of compo-
nents 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 regularly
removed. For this reason, we recommend that you have your watch serviced approximately every
5 years. Please contact an authorized IWC Official Agent.
