Abstract

This document specifies the minimum requirements and test methods for magnetic resistant watches. This document applies to magnetic resistant watches designed to withstand daily magnetic fields. Before all, we are exposed to various magnetic fields in daily life and, the watches we wear are also exposed to magnetic fields. Unfortunately, the exposure of watches to strong magnetic fields may influence their accuracy. In the case of mechanical watches, the motion of the spring balance oscillator responsible for the accuracy of the watch may be adversely affected, resulting in an influence on their accuracy. In the case of electronic watches, the rotation of the motor(s) that moves the hand(s) is affected.
