The first works in the series were launched in April 2009. They consist of videos in which sweepers move around trash to create the analog clock hands ("Sweeper's clock"), [1] a person behind a translucent screen paints a digital clock, and grandfather clocks in which a man behind a screen paints the analog hands.

The Clock is a film by video artist Christian Marclay.It is a looped 24-hour video supercut (montage of scenes from film and television) that feature clocks or timepieces. . The artwork itself functions as a clock: its presentation is synchronized with the local time, resulting in the time shown in a scene being the actual t
A mechanical movement contains all the moving parts of a watch or clock except the hands, and in the case of pendulum clocks, the pendulum and driving weights. The movement is made of the following components: [2] Power source Either a mainspring, or a weight suspended from a cord wrapped around a pulley.
The best-known surviving example is the Münster astronomical clock, whose hands move counterclockwise. Occasionally, clocks whose hands revolve counterclockwise are sold as a novelty. One historic Jewish clock was built that way in the Jewish Town Hall in Prague in the 18th century, using right-to-left reading in the Hebrew language.
The clock mechanism has three main components – the astronomical dial, representing the position of the Sun and Moon in the sky and displaying various astronomical details; statues of various Catholic saints stand on either side of the clock; "The Walk of the Apostles", an hourly show of moving Apostle figures and other sculptures, notably a ...
In striking clocks, the striking train is a gear train that moves a hammer to strike the hours on a gong. It is usually driven by a separate but identical power source to the going train. In antique clocks, to save costs, it was often identical to the going train, and mounted parallel to it on the left side when facing the front of the clock. [11]
The escapement is a mechanism in a mechanical clock that maintains the swing of the pendulum by giving it a small push each swing, and allows the clock's wheels to advance a fixed amount with each swing, moving the clock's hands forward. The anchor escapement was so named because one of its principal parts is shaped vaguely like a ship's anchor.
Relation between the speed and the Lorentz factor γ (and hence the time dilation of moving clocks). Time dilation as predicted by special relativity is often verified by means of particle lifetime experiments. According to special relativity, the rate of a clock C traveling between two synchronized laboratory clocks A and B, as seen by a ...
