Is the mechanical watch good? Give good and bad reasons.

The quality of mechanical watches varies from person to person. What is suitable is the best. ?

Mechanical watches can usually be divided into the following two types: manual winding list and automatic watch. The power source of these two machines is driven by the clockwork in the movement, which drives the gear and then pushes the watch hands, but the power source is different. Hand-made mechanical watches are all wound manually, and the thickness of the movement is thinner than that of ordinary self-winding watches, so the weight of the whole watch is relatively light. Self-winding watches use the power generated by the swing of the automatic disk at the bottom of the movement to drive the spring to generate energy, but the relative thickness of the watch book will be thicker than that of ordinary manual winding watches. The advantage of mechanical watches is that they can be used for a long time after regular maintenance and oil washing; But the disadvantage is that the error is larger than that of quartz watch, which is caused by the influence of watch quality and gravity on the movement in the watch. Usually, the error of mechanical watches is calculated by how many seconds are different every day, while the error of quartz watches is calculated by how many seconds are different every month.
