I'm sure you've heard the sketicism surrounding one feature of the new Overseas, which pairs a display-back case with faraday cage. How can one maintain antimagnetic protection without completely enclosing the movement within a soft-iron shell?
The picture above is snipped from a YouTube video found here. Back in 2014, Netherlands clothing designer Anouk Wipprecht premiered this faraday cage dress in a most spectacular fashion; by passing 1 million volts while wearing it . Wipprecht herself wore the dress for this stunt as none of the models were willing.
The principle of a faraday cage is that electromagnetic fields are channelled over the exterior of a conductive metal structure, while the interior remains free of disturbances. As you can see, complete enclosure is not required and, in fact, faraday cages for industrial and research purposes are most often mesh screens.
