Clocks are devices and instruments used to measure, record and keep time. Clocks help indicate time at any point in any part of the world. Clocks show time in hours, minutes and seconds. Clocks are available in different shapes and sizes. These days’ clocks are used at an item of décor and are available in designer editions that are displayed on mantel pieces or elsewhere in the house. Clocks are basically timepieces with a mechanism and operate on electricity or battery.
