automatic watch doesn't work？？？

What if the automatic watch doesn't work? There are many reasons why a mechanical watch won't work, such as bumps, misalignment of the movement gears, magnetization of the watch, long shelf life, and dry sludge, which can all cause the mechanical watch to fail.
What if the automatic watch doesn't work? Mechanical watches can generally be divided into the following two types: manual and automatic chaining watches. Manual chained watches rely on hand power, and if the watch suddenly stops moving, you have to consider a lack of power. Manual chained watches should be strung at the same time every day as much as possible to ensure that the watch has sufficient energy to operate in the next 24 hours.
The principle of an automatic winding watch is to operate under the action of an automatic winding mechanism that automatically rotates in any direction and can tighten the spring. Generally, a fully automatic watch should be worn on the hand for more than 8 hours per day to supplement the amount of spring, but it is not absolute. Therefore, if you do not wear it for a long time, or if you do not exercise enough after wearing it, it can also lead to the mechanical watch not moving. In such cases, manual winding can be used to solve the problem. It is worth noting that if you have not worn an automatic winding watch for more than 40 hours, you should turn the crown 20 times to restart the drive system of the movement when you wear it again.
If the reason why the mechanical watch does not work is not due to insufficient kinetic energy, it is because the mechanical watch has failed and needs to be sent to a professional maintenance personnel for repair. Remember not to disassemble the mechanical watch yourself.
Whether it is a manual or automatic chain up watch, its principle is driven by mechanical gears and springs, which inevitably cause friction during rotation. Therefore, it is necessary to add oil and lubrication after a long time of use to reduce the wear rate of parts.
