THE SEAHOLM SOLUTION
THE PROBLEM - A SMALL MAGNET?
Small magnets, like those found in your iPad cover, a refrigerator magnet, or a computer monitor, produce magnetic fields that can compromise an automatic watch. Even frequent high-altitude flying can magnetize a watch that is compliant to 4,800 A/m or ISO 764.
ISO 764 standards fall short of protecting movements in modern times.
THE SOLUTION - MUMetal PROTECTIVE CAGE
The SEAHOLM movement cage to accepts the magnetic charges when exposed to magnetic fields and "release it" once it the fields have been removed. The internal carbon steel and brass parts remain unaffected .Our watches can withstand magnetic forces to 33,500 A/m or 420 Gauss.
This is at least 7 times the ISO standard.
