A unique and exceptional neoclassical urn clock by Paul Rimbault, London, circa 1770. This singular example of a pendule � cercles tournants stands as a masterpiece of English clockmaking and design from the Georgian period.The ormolu case is of remarkable quality, with a richly ornamented square plinth base containing the movement, surmounted by an elegant lidded urn with bold scrolled handles terminating in anthemion motifs.
