Anti-magneticsm in New GMTs?

[leopardprey]

Anyone know how much anti-magnetic the new GMTs are? The new Spring that is put inside, Rolex is advertising that it is much less prone to magnetism than the old springs. I knwo the Milgaus is rated to 80,000 A/M just like the IWC Ingeniuer. Most standard swiss mechanical watches (Omega, Rolex) are rated to 4,800 A/M.

Thanks.

Well Chad don't read too much into this new parachrome hair spring. The main reason Rolex is making them,its simply to be 100% self sufficient.Now Rolex for a few years had the facility to make some of there own hair-springs.But the main supplier was Nivarox-Far owned by the Swatch group.Now most watches today have a fairly strong resistance to magnetism.And some specialist watches a lot more,but even if a watch does get magnetised today.Its quite a easy fix to de-magnetise them,and the source of the magnetism would have to be quite strong.But today most of the equipment is shielded to keep magnetism to minimum.Myself if I knew I was going to work in strong magnetic fields then something like a G/shock quartz would do.

Thanks Padi for the info. Is there a simple layman's way to de-magnetize your watch if it becomes magnetized?

Most good watchmakers after a complete strip down and service.After they have reassembled the movement they pass it through a degaussing coil before checking and re-timing watch.To make sure it's not become magnetised its quite a simple process to demagnetise any mechanical watch.

The new "parachrom" hairspring devoloped by Rolex is (according to people I have spoken to in Rolex Geneva) described as being as impervious to magnetic fields!
I will see if I can get some specific details on it`s resistance etc...and get back to you.
