A mechanical watch is a watch that uses a clockwork mechanism to measure the passage of time, as opposed to quartz watches which function using the vibration modes of a piezoelectric quartz tuning fork, or radio watches, which are quartz watches synchronized to an atomic clock via radio waves. A mechanical watch is driven by a mainspring which ...
The spiral balance spring is visible at top. A balance wheel, or balance, is the timekeeping device used in mechanical watches and small clocks, analogous to the pendulum in a pendulum clock. It is a weighted wheel that rotates back and forth, being returned toward its center position by a spiral torsion spring, known as the balance spring or ...
Verge and foliot escapement from De Vick tower clock, built in Paris, 1379, by Henri de Vick. The verge (or crown wheel) escapement is the earliest known type of mechanical escapement, the mechanism in a mechanical clock that controls its rate by allowing the gear train to advance at regular intervals or 'ticks'.

It was used from the 15th century to the early 20th century to improve timekeeping by equalizing the ...
Wheel train. In horology, a wheel train (or just train) is the gear train of a mechanical watch or clock. [ 1] Although the term is used for other types of gear trains, the long history of mechanical timepieces has created a traditional terminology for their gear trains which is not used in other applications of gears .
An automatic watch, also known as a self-winding watch or simply an automatic, is a mechanical watch where the natural motion of the wearer provides energy to wind the mainspring, making manual winding unnecessary if worn enough. [ 1] It is distinguished from a manual watch in that a manual watch must have its mainspring wound by hand at ...
This makes it inconvenient to use if the watch is being worn on the right wrist. Some manufacturers offer "left-hand drive", aka "destro", configured watches which move the crown to the left side [86] making wearing the watch easier for left-handed individuals. A rarer configuration is the bullhead watch.
