Milgauss: Anti-Magnetic Question

[wuyeah]

Hello guys,

Since Milgauss is the only Rolex watch in the line-up advertise about it is being Anti-Magnetic watch. As of this year, 2012, many new Rolex models have upgraded with parachrome hair spring such as DayDate, Submariner..etc.

My question is, Is Milgauss more anti-magnetic than other models that equipped with parachrom hairspring? If it is, what other design details features in Milgauss more anti-magnetic than other? is it the extra back plate or there are more besides parachrome + back plate combo that are not advertised that people should know about?

Is it possible that Milgauss' uniqueness that is no longer as speical as it used to?

I am just curious....
