WHY DO MECHANICAL WATCHES NEED TO BE DEMAGNETISED？

Why does a mechanical watch become magnetised?

The proximity of a mechanical watch to a strong magnetic field, for example next to an electrical appliance or a magnetic object where a magnetic field occurs, may lead to the internal balance spring being magnetised. A watch worn normally for more than 2 years is more or less magnetised.

The mechanical watch magnetised why the time is not allowed to go? How to demagnetise a mechanical watch?

After the balance spring sticking, it will lead to swinging fast, thus causing the time to be off. A compass can be used to detect whether the magnetisation.

When a watch is magnetised it will not go away on its own and will need to be demagnetised with a demagnetiser to restore it to normal.

Watch magnetisation and watch magnetisation detection：

Mechanical watches are exposed to too many objects, such as computers, electric toys, mobile phones, magnets, etc., which cause the hairspring to magnetize and stick, thus causing the watch to go too fast, too slow or stop, in which case a demagnetizer is required to eliminate the watch magnetism.

When the mechanical watch is close to the compass (for magnetic detection only) and rotates around the compass, the compass hand follows the rotation of the watch, which means that the watch is magnetised and needs to be demagnetised by a demagnetiser.
