A clock with case in the form of an urn or classical vase. The urns may be of marble, porcelain, crystal or patinated bronze, usually set with gilt-bronze mounts and often made with a paired calendar in the same form. Most vase clocks are revolving-band clocks, but they may also be fitted with a conventional dial like the Sevres porcelain clock. They were usually of the highest quality and are often found in a dazzling garniture de cheminee, the urn clock flanked by candelabra of similar form.
