The difference between electronic watch and machinery
That is, the power system of mechanical watches is clockwork, and the workmanship is quite complicated, which requires a lot of time for famous teachers to build. But electronic watches are relatively simple in workmanship, so electronic watches are relatively cheap, and good mechanical watches sell tens of thousands or even millions.
White-collar workers, business people, buy a mechanical one. If you are cute, lively and like non-mainstream, buy an electronic one.
