The Trinity College Clock mechanism and the Keeper of the Clock, Dr Hugh Hunt in February 2019. The clock is the subject of a current project coordinated by Dr Hugh Hunt, Fellow of Trinity College Cambridge, calibrating it against the National Physical Laboratory time signal and other variables, including the amplitude of the pendulum, humidity, air temperature, air pressure, and air density.

Older Atmos clock. The first clock powered by changes in atmospheric pressure and temperature was invented by Cornelis Drebbel in the early 17th century. Drebbel built as many as 18 of these, the two most notable being for King James VI & I of Britain, and Rudolf II of Bohemia. The King James clock was known as the Eltham Perpetuum, and was ...
William Hamilton Shortt (1881–1971) was a railway engineer and noted horologist, responsible for the design of the Shortt-Synchronome free pendulum clock, a widely used time standard, employed internationally in observatories in the period between the two World Wars.
Zamboni's clock had a vertical needle supported by a pivot and was so energy efficient that it could operate on one battery for over 50 years. In 1840, Alexander Bain, a Scottish clock and instrument maker was the first to invent and patent a clock powered by electric current. His original electric clock patent is dated October 10, 1840.
The Atmos clock, made by Jaeger-LeCoultre, is a type of torsion pendulum clock that winds itself. The mainspring which powers the clock's wheels is kept wound by small changes in atmospheric pressure and/or local temperature, using a bellows mechanism. Thus no winding key or battery is needed, and it can run for years without human intervention.
A pendulum clock is a clock that uses a pendulum, a swinging weight, as its timekeeping element. The advantage of a pendulum for timekeeping is that it is an approximate harmonic oscillator : It swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates.
A modern LF radio-controlled clock. A radio clock or radio-controlled clock (RCC), and often colloquially (and incorrectly [1]) referred to as an "atomic clock", is a type of quartz clock or watch that is automatically synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock.
On the left is the primary pendulum in its vacuum tank. The Shortt–Synchronome free pendulum clock is a complex precision electromechanical pendulum clock invented in 1921 by British railway engineer William Hamilton Shortt in collaboration with horologist Frank Hope-Jones, [1] and manufactured by the Synchronome Company, Ltd., of London.
