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 ...

The gravity remontoire was invented by Swiss clockmaker Jost Bürgi around 1595. Usually the "Kalenderuhr" (three month running, springdriven, calendar-desk-clock) Bürgi is considered the oldest surviving clock with a remontoire, even if it does not provide power to the escapement during the few seconds of the daily cycle where the remontoire weight gets wound up by the spring.

The same timeline seems to apply in Europe, where mechanical escapements were used in clocks by that time. Up to the 15th century, clockwork was driven by water, weights, or other roundabout, relatively primitive means, but in 1430 a clock was presented to Philip the Good, Duke of Burgundy, that was driven by a spring. This became a standard ...
Clockwise motion (abbreviated CW) proceeds in the same direction as a clock's hands relative to the observer: from the top to the right, then down and then to the left, and back up to the top. The opposite sense of rotation or revolution is (in Commonwealth English ) anticlockwise ( ACW ) or (in North American English ) counterclockwise ( CCW ...
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 GIF is slowed down to make the mechanism movement easier to see. A Roskopf , pin-lever , or pin-pallet escapement is an inexpensive, less accurate version of the lever escapement , used in mechanical alarm clocks , kitchen timers , mantel clocks and, until the 1970s, cheap watches now known as pin lever watches .
In many clocks, the outer end is attached to a stationary post. The spring is wound up by turning the arbor, and after winding its force turns the arbor the other way to run the clock. The disadvantage of this open spring arrangement is that while the mainspring is being wound, its drive force is removed from the clock movement, so the clock ...
