Quartz quartz watches belong to the second generation of watches, generally refers to watches that use batteries and quartz oscillators to calculate and display time, and its movement is made of quartz frequency. The common quartz watches nowadays can be divided into pointer type quartz watches and digital quartz watches. Within the normal temperature range, the best feature of a quartz watch is its accuracy, with a monthly error within about ±15-20 seconds.
Among them, quartz watches are further divided into:Pointer quartz watches: use battery power to generate the frequency of the quartz, and then use the IC board to de-frequency and control the coil and magnetic carriage, so that it drives the gear train and turns the hands, whose hour and minute hands are largely driven by electricity.Digital quartz watches: The basic principle is the same as a pointer-type quartz watch, but instead of a gear train, it directly displays the time with an LCD chip.
