Detailed explanation-1: -So, Quartz crystals are normally used in quartz clocks etc. is chemically silicon dioxide. Quartz crystals are piezoelectric which means it generates a tiny electric voltage in response to squeezing. The reverse is also true. The quartz crystal oscillates at a precise frequency when a voltage is applied to it.
Detailed explanation-2: -That quartz crystal serves as the oscillator. The battery sends electricity to the quartz crystal through an electronic circuit. The quartz oscillator vibrates quickly and with precise frequency (32, 768 times/second) in response to the electronic charge.
Detailed explanation-3: -Why is quartz used in watches? Quartz is used in watches because it’s at least 100 times more accurate than previous mechanisms and lasts for a very long time.
