Older viewers could recall the dangling weights and/or coiled springtimes that made use of to drive clocks mechanically. They used rotational pressure (torque) to a major equipment, which in turn triggered various other gears to turn at various, thoroughly determined rates. Calibrated pendulum and escapement mixes prevented the equipments from freewheeling.
