Every watch factory in that era was more accurate in comparing the mechanical watches of each other, but Seiko suddenly published the quartz movement watch, the accuracy is several times higher than the mechanical watch, and does not need to be corrected frequently. The market has brought no small impact. Under the quartz storm, the Swiss traditional watchmaking industry plummeted, the company closed down, and a large number of employees were laid off. During the quartz storm, more than 90,000 watch operators in Switzerland were unemployed. From the current point of view, mechanical and quartz watches are beneficial. Mechanical watch: The manual winding watch usually drives the watch by turning the crown to provide energy for the barrel. The driving process is the most traditional winding mode by mechanical principle and construction. There are some problems with micro-days, but the advantage is that the whole machine does not need to worry about IC performance. If you maintain it once every two years, you can continue to use it. Therefore, regardless of the price, the family is usually mechanical. Table Quartz watch: Accurately, because the battery is supplied with power to the quartz crystal, a stable oscillation signal is generated, which is transmitted to the IC integrated circuit board to push the gear train to complete the operation, but it is often necessary to worry about battery leakage, quartz tube oscillation, and IC performance. The problems are therefore pros and cons.
