Magnetic-resistant wristwatch

Magnetically resistant

— strong magnetic fields can adversely affect the performance of any watch. Mechanical models are especially sensitive to them (see "Type of mechanism") — in such devices there are many small moving parts, the magnetization of which can lead to a complete stop of the movement. However, for quartz watches, such effects are undesirable. So magnetic protection can be found in all kinds of mechanisms; it is usually implemented due to the special design of the case, and in mechanical models — also through the use of special anti-magnetic materials.

Note that this feature significantly affects the cost; at the same time, most household sources of magnetic fields (speakers, mobile phones, magnetic fasteners on clothes and accessories, etc.) are not so powerful as to seriously damage even an ordinary clockwork. So it makes sense to specifically look for magnetically resistant watches mainly for use in special conditions. For example, such a watch can be useful to a physician working with a magnetic resonance imaging scanner, or an engineer maintaining equipment at a power plant.
