Quartz watches are made of quartz resonators. They are divided into electronic quartz watches and mechanical quartz watches. There are three kinds of quartz watches: pointer watches, digital watches and double explicit watches. Quartz watches are powered by batteries.
In terms of composition, the pointer quartz watch is the same as the pointer quartz clock, and the digital quartz watch is the same as the digital quartz clock.
1. Quartz watch's time-hand is jumping one by one, and the time-hand is very accurate. Generally, the monthly difference is less than 15 seconds, and there are three and two needles.
2. The integrated circuit is used in the machine core. The structure is much simpler than that of the machine core of the mechanical watch, and the assembly is very simple.
3. Easy to use, wear without winding, a battery can generally be used for 2-3 years. But some quartz watches use lithium batteries with a service life of about 7-8 years.
4. Quartz watches are relatively cheaper than mechanical watches (the same style as the brand), but some high-end brand quartz watches are expensive because of the good brand, good appearance materials (18K gold or diamonds or precious metals), excellent design.
1. Different from quartz watches, mechanical watches run continuously and uninterruptedly.
2. Because of the complexity of the machine core of the mechanical meter, the travel time error is relatively large (depending on the brand) generally within the permissible range of +45 seconds. The error of the observatory core is small, and the error of one day is normal within - 4/+6 seconds. The running time error of mechanical watches can not be accumulated. Watches need to be debugged after a period of time.
3. The process is fine and easy to use. It can walk for more than 36 hours with full spring.
4. The service life of the machine core is long, and the luxury machine watch has the value of collecting.
5. Appearance is thicker and heavier than quartz watches (depending on the brand). Some brands of hand-operated mechanical watches are also thin.
