Advantages and disadvantages of quartz watch and mechanical watch;
Quartz watches are driven by timely vibration, and batteries are needed as power in this process, so when the batteries are dead, quartz watches will stop working.
The service life of an ordinary battery is generally about 2 years, so compared with a mechanical watch, this has become its short board, and the battery needs to be replaced! But the time of quartz watch is very accurate, and the error of one day is between -0.5 and +0.5 seconds.
