Watches and clocks are often found stopped with the mainspring fully wound, which led to a myth that winding a spring-driven timepiece all the way up damages it. [16] Several problems can cause this type of breakdown, but it is never due to "overwinding", as timepieces are designed to handle being wound up all the way.
A grandfather clock (also a longcase clock, tall-case clock, grandfather's clock, hall clock or floor clock) is a tall, freestanding, weight-driven pendulum clock, with the pendulum held inside the tower or waist of the case. Clocks of this style are commonly 1.8–2.4 metres (6–8 feet) tall with an enclosed pendulum and weights, suspended by ...
Keys of various sizes for winding up mainsprings on clocks Mechanism of a Wall Clock, Ansonia Co. 1904. Often power for the device is stored within it, via a winding device that applies mechanical stress to an energy-storage mechanism such as a mainspring, thus involving some form of escapement; in other cases, hand power may be utilized.

Winding and setting In order to function as time keepers, and to prevent damage to clockwork, clocks must be regularly wound. An established winding schedule eliminates the threat of over-winding."Traditionally, the job of winding the clocks was given to an horologist or a trained individual.
The core of the keyless mechanism is a gear on the watch's winding stem, the clutch (or castle wheel in Britain), with two sets of axial gear teeth on it, which slides in and out. When the stem is pushed in, a lever slides the clutch out, and the outer set of teeth engages a small wheel train which turns the mainspring arbor, winding the ...
It is usually a planetary gear mechanism (epicyclic gearing) in the base of the fusee "cone" which then provides turning power in the opposite direction to the 'winding up' direction therefore keeping the watch or clock running during winding. Most fusee clocks and watches include a 'winding stop' mechanism to prevent the mainspring and fusee ...
He made clocks that would run up to one year on a winding. He also made precision astronomical regulator clocks based on the torsion pendulum, but only four were sold. The German Anton Harder apparently independently invented and patented the torsion clock in 1879-1880. [ 4 ]
