Omega has unveiled the production version of the Seamaster Aqua Terra > 15,000 gauss, which has the highest level of magnetism resistance of any wristwatch today. I like this watch. This could be my first Omega in my collection!
Resistant to magnetic fields of over 15,000 gauss (or 1,000,000 A/m or 1.5 Tesla), the Omega Seamaster Aqua Terra > 15’000 gauss is a big technological achievement. It far exceeds the magnetism resistance of other watches, thanks to the use of proprietary non-magnetic alloys for key movement components. This means the movement itself is resistant to magnetism, in contrast to the traditional method of dealing with magnetism, which shields a regular movement via soft iron enclosure. A soft iron cage usually protects against a magnetic field of up to 1000 gauss or 80,000 A/m, but at higher levels of magnetism the soft iron protection is ineffective.
