Quartz WatchesQuartz watches are the most common kind of watches. Under the conditions in a watch quartz crystals vibrate over 32,000 times a second. Monitoring these vibrations ensures really accurate time keeping. Quartz watches lose only about 10 seconds of time a month. Quartz watch batteries also only require replacing once every one or two years.
Analog Quartz Watches
Analogue watch faces have numbers, Roman numerals, or tick marks indicating intervals of time while digital faces provide an exact readout in hours, minutes and seconds.
Digital Quartz Watches
Digital watches often have extra features such as depth sensors, Global Positioning System (GPS), altimeters, calculators, phone books, and compasses.
Get Ready to Wind Mechanical Watches
Mechanical watches run from a spring called the mainspring. This powers an oscillator which usually vibrates 28,000 times an hour. Mechanical watches often require more skill and time to build than Quartz watches and so cost a little more. Mechanical watches can be manual where you wind the watch yourself or automatic.
Automatic Mechanical Watches
Automatic mechanical watches use a rotor swing which responds to motion, winding the mainspring running the watch. Automatic mechanical watches often come with a transparent or partially-transparent display so you can see the rotor in action. If you wear an automatic mechanical watch for more than 12 hours per day, your motion will keep the watch mechanism running. You'll need to wind your watch if you don't wear it for a few days.
