Wall Clock

• Battery Wall Clock
• Mechanical Wall Clock

Wall clocks are the most commonly owned clocks at both home and work. These time pieces come in a variety of different types and can be either mechanical or battery-powered. Some simple wall clocks are powered by battery-powered "quartz" movements, while other, more traditional clocks are powered by wind-up mechanical movements. Both varieties can have chimes that play on the quarter hours and strikes that tune the number of the hour. Some battery clocks even pick up their time over the air from the atomic clock.
