A quartz clock operates by a piece of quartz crystal. The crystal's wavelength gives off a signal which is read by a digital logic circuit. This signal is then translated into increments of time. The digital data is converted to hours, minutes and seconds.

the piezo-eletric property of a crystal is the principle of quartz clock
The frequency of a vibrating quartz crystal is far more stable than older means of time measurement.
It's a tiny crystal of quartz that provides a constant input to the clock IC. When stimulated by electricity, quartz oscillates at a steady frequency of 32768 vibrations per second. This known, accurate vibration is used to make the internal clock work.
A crystal oscillator is a circuit that generates the clock signal that controls the timing of a typical computer. As you may have already guessed, the frequency is mainly controlled by a highly pure crystal of quartz (silicon dioxide).
When a tiny alternating voltage is applied across a quartz crystal it oscillates very precisely. The oscillations can therefore be used as a clock.
A quartz clock is a clock that uses an electronic oscillator that is regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks are at least an order of magnitude more accurate than good mechanical clocks. Generally, some form of digital logiccounts the cycles of this signal and provides anumeric time display, usually in units of hours,minutes, and seconds. Since the 1970s, they have become the most widely used timekeeping technology.
Walter G. Cady built the first quartz crystal oscillator in 1921. However, the properties of quartz making this possible were first discovered by Jacques and Pierre Curie in 1880.
In 1927 Warren Morrison developed a very large and accurate clock by testing the vibrations of a quartz crystal from an electrical circuit. In 1504 Peter Heinlein Nuremberg created the very first wrist watch in Germany.
