Rolex and anti-magnetism

[Solar]

Greetings all:

Any info out there about the general anti-magnetic capabilities of the Sport line of Rolexes? I read about "soft iron cores" from time to time in watch reviews. What is "soft" iron? And how does a ferrous metal like iron prevent the watch from being magnatised? I would have thought iron would attract magnetism? What do I know.............

Anyways, are the Subs/GMTs/SDs fairly proof against magnetic damage as far as mechanical watches go?

Always learning,

Chris

Here's the definition I dug up for soft iron:

A form of iron with a low carbon content that is unable to retain magnetism and is used to make the cores of electromagnets, motors, generators and transformers. (and watches?)

I'd guess that the soft iron would become temporarily magnetized in the presence of a field, preventing the field from reaching and affecting the mainspring?

Thanks Al, much appreciated.

Any field experience out there about the actual anti-magnetic capacity of the sport line of Rolexes? Anyone out there had theirs fried by a magnet (price scanner, speakers, coirdless drill, etc etc).

Cheers,
