The Lever Escapement is a crucial mechanism used in mechanical watches and clocks. It regulates the release of energy from the mainspring, allowing the gear train to move at a controlled rate. This ensures accurate timekeeping by dividing time into equal intervals. Invented in the 18th century, the lever escapement consists of a lever, a pallet fork, and a gear called the escape wheel. When the escape wheel turns, it engages with the pallet fork, which then releases the gear train in precise increments. This design significantly improved the accuracy of timepieces compared to earlier mechanisms.
