What does "anti-magnetic" mean concerning a watch?

The term "anti-magnetic" in relation to a watch specifically refers to its ability to resist interference from magnetic fields. Watches can be affected by magnetic fields, which can cause inaccuracies in the timekeeping function. Therefore, an anti-magnetic watch is engineered with materials or designs that protect its internal components from the disruptive effects of magnetism. This feature is particularly important for precision timekeeping, as even minor deviations caused by magnetic fields can lead to significant time errors.

Understanding this concept highlights the importance of anti-magnetic properties in the context of professional and everyday usage, especially in environments where magnetic fields are prevalent.
