mechanical clock

A mechanical clock is a machine that displays time by linking a device with regular movements to a counting mechanism. The core of a mechanical clock is the escapement, which controls the energy transfer from the power source (a weight or spring) to the counting mechanism. Early clocks, like the verge escapement, were large and often housed in towers. Improvements, such as the pendulum and the anchor escapement, significantly increased accuracy. Portable clocks emerged with the invention of spring-driven mechanisms around 1450. Modern mechanical clocks, while less common than electronic ones, are descendants of these historical innovations.12
