This device functioned as a geared analogue computer after its creation during the first-century BCE timeframe, being somewhat astrolabe-like, and had been designed for calculating astronomical positions and particularly listing eclipses.
While being set, it is turned by the setting mechanism – in modern clocks, a setting knob on the back of the clock. In watches during setting it is turned by the minute wheel, which is turned by the keyless works. In older clocks the setting was done by opening the face and manually pushing the minute hand which rotated the cannon pinion ...
Lavet-type stepping motor of a quartz clock. A black rotor sprocket provides the mechanical output. The Lavet-type stepping motor has widespread use as a drive in electro-mechanical clocks [1] and is a special kind of single-phase stepping motor. Both analog and stepped-movement quartz clocks use the Lavet-type stepping motor (see Quartz clock).
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 ...
