How does magnetism affect a quartz watch?
It usually doesn’t affect digital quartz watches, but it will affect analog watches. Powerful magnetism can affect the tiny electric motor that turns the hands. Even though your watch may gain or lose time while under the influence of a magnetic field, it’s function will return to normal once the magnetism is removed. Always avoid putting your watch near door magnets, electric appliances, medical equipment, headphones, loudspeakers and other similar type items.
