An English Longcase Clock, often known as a Grandfather Clock, is a tall freestanding clock housed within a timber case and powered by a weight-driven mechanical movement. Produced from the late seventeenth century onwards, English longcase clocks are celebrated for their finely crafted oak, walnut or mahogany cases, painted or brass dials and exceptional clockmaking. They remain among the most iconic and desirable forms of antique timepiece. *Related Terms*\ Eight-Day Clock, Brass Dial, Clock Movement, Grandfather Clock, Longcase Clock, Weight-Driven Clock.
