Hi. I have one swiss chronograph quartz watches. It use ETA G10.711 movement. Lately, it is not keeping a good time, it starts loosing time around 1-2 minutes within a week. My friend told me my watch had been magnetized. i had test put that watch around a compass, yes the compass hand start moving when my watch is around it. Reading at a forum , demagnetized the mechanical movement is quite common but the quartz movement has a magnet component and demagnetized it could damage the movement itself. Maybe I have to demagnetized only the case and bracelet maybe while taking the movement off. Anyone here ever use demagnetized procedure? maybe for the Quartz watches.
