Magnetization can indeed impact automatic watches, as with all mechanical timepieces. When these watches come into contact with potent magnetic fields, their metal components may become magnetized. This magnetization can lead to the watch running too quickly, too slowly, or it may even halt its operation altogether.
The susceptibility of an automatic watch to magnetization hinges on various aspects. These include the intensity of the magnetic field, the craftsmanship of the movement, and the types of materials used in building the watch.
In summary, though automatic watches can be influenced by magnetic fields, the extent of this impact can greatly differ based on multiple elements. If magnetization is a concern, regular servicing of your watch can help maintain its accuracy and overall performance.
