The movement of quartz watch is mainly composed of quartz resonator, integrated circuit, battery and other parts, and its structure is relatively simple. Compared with the complicated mechanical structure of mechanical watches, quartz watches have fewer parts and are easier to assemble. There is no need to wind it regularly like a mechanical watch, as long as the battery has enough power, it can keep normal operation. An ordinary quartz watch battery can generally last for 2-3 years, while some quartz watches using lithium batteries can last for about 7-8 years..syi
