Watches with a soft­iron inner case provide a higher
level of protection against magnetic fields and far ex­
ceed the requirements of DIN standard 8309. Never­
theless, it is still possible for the watch movement to
be magnetized in the close proximity of very strong
magnets. We therefore recommend that watches with
a soft­iron inner case also be kept away from direct
contact with strong magnets.
Should there be a sudden change in the precision of
your timepiece, please contact an authorized IWC
Official Agent to have your watch checked for mag­
netism.
