Tick-tock: A story of watches

Watches remind us of the passage of time, and are also carriers of human civilization and technological development. How were watches with various functions, exquisite craftsmanship, and unique shapes created? How have they developed to this day? In fact, the time of watches, like the time of life, has gone through years of ups and downs. There are always moments when things don't go smoothly, but as long as you find the root of the problem, re-polish and oil it, perform a "major operation", and patiently wait for the opportunity to come, even the most difficult challenges will eventually pass.
