Huygens' maintaining power in use. The weight drive used by Christiaan Huygens in his early clocks acts as a maintaining power. In this layout, the weight which drives the clock is carried on a pulley and the cord (or chain) supporting the weight is wrapped around the main driving wheel on one side and the rewinding wheel on the other.
The components of many clocks are extremely susceptible to water damage. Because of the complexity of these objects, they are very challenging to dry. It may be extremely difficult, depending upon the severity of the water damage, to repair or restore the clock to its correct condition.
A fusee (from the French fusée, wire wound around a spindle) is a cone-shaped pulley with a helical groove around it, wound with a cord or chain attached to the mainspring barrel of antique mechanical watches and clocks.

In older clocks the setting was done by opening the face and manually pushing the minute hand which rotated the cannon pinion ...

The backward motion of the escape wheel during part of the cycle, called recoil, is one of the disadvantages of the anchor escapement.It results in a temporary reversal of the entire wheel train back to the driving weight with each tick of the clock, causing extra wear in the wheel train, excessive wear to the gear teeth, and inaccuracy.
The movement of a digital watch is more commonly known as a module. In modern mass-produced clocks and watches, the same movement is often inserted into many different styles of case. When buying a quality pocketwatch from the mid-19th to the mid-20th century, for example, the customer would select a movement and case individually. Mechanical ...
