IWC 책자의 한 내용입니다.

protection against magnetic fields

Like many of the Pilot's Watches, some of the models in the ingenieur family also offer optimum protection aginst the effects of external magnetic fields in the form of a soft-iron inner case.
The inner back plate, casing ring and dial are made from pure iron and are particularly adept at conducting magnetic flux lines around the movement.
This combination prevents magnetic fields from reaching the movement and guarantees maximum precision in both normal and extreme situations.
Depending on the model in question, the protection provided here - of up th 80,000 Ampere/metres - exceeds the Swiss norm for "antimagnetic watches" by more than sixteen-fold.
