Mechanical watches rely on the clockwork to provide power, through the gear to time. Mechanical watch is divided into manual winding and automatic winding. As the structure is more complex, the phenotype is more heavy. Because of the characteristics of travel time principle, subject to gravity, mechanical friction, temperature changes, the use of such factors as the impact of error so relatively large quartz watch. Quartz watches rely on the battery to power the extremely stable high-frequency vibration of quartz crystal as a benchmark, so the quartz watch travel time is more accurate, the cost is relatively low, it can be described as inexpensive. Of course, the appearance of quartz watch, although the impact on the traditional mechanical watch large, but still can not completely replace the mechanical watch, many men or collectors still like the traditional sense of mechanical watches.
