a piezoelectric element excites the resonant frequency of a small quartz crystal, locking on that frequency by resonant feedback. From there it's just electronic counting of the driver oscillations.

A good quartz clock/watch uses a mini quartz crystal. This then uses a battery to send enough energy to make the quartz vibrate once per second. The output of a quartz clock is 32768Hz per second that can be divided by 2 15 times. Plz like this???

Quartz crystals are piezoelectric (convert mechanical stress to electrical energy and vice versa), and have very stable resonant frequencies. In a quartz clock, a quartz crystal with a specific resonant frequency (typically in the kilohertz or megahertz range) is used to control the electronics. For e.g. the output of a 32kHz crystal (actually 32768Hz) can be run through 15 divide-by-2 stages to give a very precise one pulse per second.

the quartz crystal holds a charge for exactly 1 second... intrestingly a good example of one is sitting in front of you theres a quartz crystal timeing your system right now
