1. Watch magnetization: Watch magnetization is one of the common reasons why watches slow down. Even antimagnetic watches cannot be placed next to some electrical appliances, because some parts are not antimagnetic and will be magnetized after a long time. The watch is magnetized, which requires a professional watch maintenance agency to degauss it.
2, lack of power: mechanical watches are divided into manual winding and automatic winding. Lack of power is often an important reason why watches slow down or even stop running. Manual winding of mechanical watches can solve the problem by winding, while automatic winding of watches is mostly due to people who don't wear it for enough time (less than 8- 10 hours a day) or exercise less. Friends or old people in the general office often have mechanical watches slow down due to lack of power.
3. Insufficient maintenance leads to mechanical failure: if you don't pay attention to it in daily use, you will encounter problems such as collision, which will loosen the internal parts of the watch and lead to inaccurate walking. Dust and foreign matter make the teeth of the gear train get stuck with each other, and some watches display too much or too little oil, which will make the electronic watch difficult to use. When you encounter these faults of stepping motor and gear train, clean it, remove foreign objects and refuel. Some parts of the watch core are damaged and need to be replaced.
4. The mechanical watch moves fast first because the position error of the watch is relatively large. For example, the accuracy of walking on the surface of the hand is different from that of walking under the surface, and the lucky error of the facade is relatively large. When worn, the daily error of its comprehensive uniformity is relatively increased. Position error is a close indicator of watch luck performance, and the general change indicator is as small as possible.
5. There is also a common problem when the mechanical watch moves fast, that is, the secondary outer ring of the hairspring rubs the outer column of the hairspring, which is also manifested vertically and dynamically, especially when the watch is knocked before, and the hairspring is most prone to problems after deformation; This sub-position depends on the motion. If the ETA-type men's watch movement is widely used today, it is easier to display the left or upper position of the watch handle on the wrist. In this case, it is necessary to adjust the gap between the secondary outer ring of the hairspring and the outer post of the hairspring, and there should be a reasonable safe distance between them.
