Quartz watch is a battery-driven electronic watch, its core component is a quartz crystal, quartz crystal through a stable circuit to accurately time. Say something about quartz watches: The history of quartz watches: The first quartz watch was introduced in 1967 by the Swiss company Svoka. It uses electronic oscillators and quartz crystal technology, and its accuracy is much higher than that of traditional mechanical watches. Advantages of quartz watches: quartz watches have high accuracy, and the error is within a few seconds per month, while the error of mechanical watches may reach a few minutes. In addition, the quartz watch also has the advantages of simple structure, easy maintenance, good seismic performance and so on. The working principle of the quartz watch: The circuit of the quartz watch includes an electronic oscillator and a quartz crystal. The quartz crystal will oscillate under the action of the electric field to generate a high-precision time base signal. The electronic oscillator converts the time base signal into an electrical signal that drives the needle. Classification of quartz watches: quartz watches can be divided into men's watches, women's watches, children's watches and other types according to the shape, and can be divided into ordinary quartz watches, multifunctional quartz watches, solar quartz watches and other types according to the function. Quartz watch maintenance: quartz watch maintenance is relatively simple, need to pay attention to avoid the impact of collision, water, temperature changes and other factors, while the need to pay attention to replace the battery and regular cleaning case, watchband and other components. In short, the quartz watch is a high precision, simple structure, easy to maintain electronic wrist watch, has a high practical value and collection value.
