what is quartz movement

A quartz movement is a type of watch movement that uses an electronic oscillator regulated by a quartz crystal to keep time. The quartz crystal oscillator creates a signal with a very precise frequency, which allows quartz clocks and watches to be accurate to within a half second per day. Quartz movements are powered by a battery and require no winding. They are very accurate and require minimal maintenance aside from battery replacements. Quartz movements tend to be low-cost since they are battery-powered and have few moving parts. The strength of quartz movements lies with their impact resistance, and they are much simpler than mechanical movements. The inhibition-compensation logic of some quartz movements can be regulated by service centers with the help of a professional precision timer and adjustment terminal after leaving the factory.
