Ball Watch Company Engineer M Marvelight NM2128C-S1C-BK. Well thought through anti magnetic timepieces. Most of the BALL watches boast superb anti magnetic cases constructed with corrosion resistant ferritic stainless steel materials. Furthermore, a soft iron inner jacket, consisting of a back plate, a ring surrounding the movement and the dial, protects the inner workings of the watch. This special alloy, reinforced by the shape of the case, prevents magnetic fields from penetrating as far as the movement and having an adverse effect on its accuracy.
