What is a magnetic field?

We are surrounded by magnetic fields, the strength of which varies depending on our environment. If they are strong enough, they may affect the movement of your watch by disturbing its ability to function. A magnetic field may cause a quartz watch to lose several seconds. However, as soon as it emerges from the magnetic field it will regain its normal functioning. Magnetism may disturb mechanical watches and affect their functioning by making the spring of the movement stick. You are therefore recommended to avoid magnetic fields on a permanent basis, or to neutralise them.
