Magnetism, what can get magnetized?

[Nimettomana]

Hi all,

So my post is slightly related to the earlier thread, but wanted to ask. If I were to purchase a Rolex Datejust or an Oyster Perpetual, or then my favorite the GMT Master II, what kind of problems would I face with magnetism? All of them have the blue Parachrom hairspring, what other parts are ever likely to get magnetized?


BTW, who here would opine that the Oyster Perpetual, red grape would not be suitable for men?

Thanks a lot.
