Introduction to Quartz Clock:How Digital Watch Works!!

Quartz Clock or Digital Watch:

  

                                              Inside a quartz clock or watch, the battery sends electricity to the quartz crystal through an electronic circuit. 

                          

                                            The quartz crystal oscillates (vibrates back and forth) at a precise frequency: exactly 32768 times each second. The circuit counts the number of vibrations and uses them to generate regular electric pulses, one per second. 

                                          

                                            These pulses can either power an LCD display(showing the time numerically) or they can drive a small electric motor (a tiny stepping motor, in fact), turning gear wheels that spin the clock's second, minute, and hour hands.
