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.
