What does the term "anti-magnetic" actually mean within the watch industry? The existing standard is defined thus: if a mechanical watch does not stop when exposed to a magnetic field of 4,800 A/m and subsequently does not deviate by more than 30 seconds per day, it can be called "anti-magnetic". Our watch collections achieve this by a special case design constructed with corrosion-resistant ferrite stainless steel materials and a special inner soft iron jacket consisting of a back plate and a ring surrounding the movement and the dial. This special alloy, reinforced by the shape of the inner case, prevents magnetic fields from penetrating as far as the movement and has no adverse effect on its accuracy.
