This site tells about revolutions in time keeping.My favorite page on this site tells about the quartz watch.Hereís how it works:it has a tiny quartz crystal in it.Two iron bars squish the crystal like Jell-O but the crystal is not crushed.It has a quartz shaped element. (I donít know what this element is.)And it also has a quartz oscillator.For more information visit http://www.britannica.com/clockworks/main.html
