Which Citizen quartz watch is the most accurate time keeper?
Quartz is a crystalline mineral, silicon dioxide, that is found in abundance in the earth’s crust and is the principal component of sand. The quartz used in watches is synthetic, or man-made. Watch manufacturers use synthetic quartz crystals rather than natural ones because they have more consistent properties. A quartz watch is one that measures time by means of a paper-thin piece of synthetic quartz. The quartz vibrates very quickly in response to an electric charge; it is these vibrations that enable the watch to keep time. Quartz watches have either an analog dial, with rotating hands, or a digital display, which shows the time with numbers. Most analog watches have quartz movements. All digital ones do.
