Silver, gilded silver and filigree, Holland, The Hague, 1665-70, made by H.C. Breghtel

The clock is in the form of a temple with a cupola surmounted by an allegorical figure representing Time. Beneath the pierced dome, twelve reliefs separated by pilasters represent the Signs of the Zodiac.

The four sides are designed as triumphal arches flanked by Corinthian columns; the front and sides contain dials and the back has a door providing access to the movement. The pedestal of the clock is embellished with a series of plaques representing the seasons in pastoral settings; the ages of man in domestic contexts and appropriate mythological scenes. The clock is mounted on four ball feet covered with acanthus foliage, each foot is on a shaped square moulded base.

The surface of the case is decorated with applied pierced embossed and filigree silver, partly gilt, representing scrolling foliage, swags of flowers, cornucopia and classical heads. The eight-day movement strikes the hours on a bell in the top of the cupola.
