Digital electronic watch is a very common type of watch. Because of its simple use, accurate timing and many functions, it is loved by the majority of young people. In daily use, people will inevitably use improperly, which may easily cause the digital electronic watch to malfunction.

1. The battery of the watch is out of power and the watch stops working: at this time, a new battery should be replaced. The old battery should be taken out in time, so as not to cause the movement to be corroded by the running liquid for too long.
2. The LCD panel of the digital watch has expired and cannot continue to display: the LCD panel will gradually decline during use, resulting in failure. For popular digital watches below 100 yuan, the service life of the LCD panel is about five years, and the service life of the LCD panel of a better digital watch is five to seven years, and it needs to be replaced when it expires.
3. Button failure: For digital watches with better quality, the buttons generally do not fail, and pressing the wrong button will not damage the performance of the watch. But for popular digital watches, if you press too hard, the watch buttons will fail.
4. The battery leaks, causing the circuit of the watch to be blocked: the battery quality is not good, or the watch is frozen by high temperature and low temperature, which will cause the battery to leak. This fluid can corrode the contacts of the power path, causing malfunction.
