An electric clock is a clock that is powered by electricity, as opposed to a mechanical clock which is powered by a hanging weight or a mainspring. The term is often applied to the electrically powered mechanical clocks that were used before quartz clocks replaced them in the 1980s. The first experimental electric clocks were constructed around 1840, but they were not widely manufactured until mains electric power became available in the 1890s. In the 1930s the synchronous electric clock replaced mechanical clocks as the most widely used type of clock.

Famous quotes containing the words electric and/or clock:
“Flabby, bald, lobotomized,
he drifted in a sheepish calm,
where no agonizing reappraisal
jarred his concentration of the electric chair—
hanging like an oasis in his air
of lost connections. . . .”
—Robert Lowell (1917–1977)
“We are hardly ever grateful for a fine clock or watch when it goes right, and we pay attention to it only when it falters, for then we are caught by surprise. It ought to be the other way about.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
