The clocks are housed in a polished rectangular black wooden case on a shaped stepped pedestal. Decorative columns made of black wood with thin facets, bases, and capitals made of yellow metal are positioned at the outer corners of the case. The case is topped with a flat roof featuring a decorative cornice, on which sits a black wooden structure in the shape of a sarcophagus. Wooden finials are placed at the corners of the roof. The sides of the sarcophagus are closed with an engraved openwork gilded grille. Crowned with a decorative four-pitched gilded grille with a finial on top, the structure features arched windows on the sides that are closed with the same type of openwork engraved grilles. On the sides, beneath the cornice, are folding decorative handles for carrying. The reverse side of the case is closed with a glass door. The front side of the clock features an arched brass dial shield, behind a glass door with an arched gilded frame. The shield is adorned with engraved images of branches, leaves, and fantastic creatures. The central focus of the shield is a wide circular dial with minute markings and Arabic numerals at five-minute intervals, black Roman numerals for the hours with images of royal lilies between them, a quarter-hour scale, and two openwork central hands. Along the outer edge of the dial are levers for silencing, chiming, and music. Inside the ring, near six o’clock, there is a square calendar window, above which, near three o’clock and around nine o’clock, are round holes with square pins for the winding key. The axis of the hands features a curved window for the pendulum movement indicator. The window displays an inscription in English providing the name of the clockmaker "Simon Decharms" and the place of manufacture – London. In the corners of the square part of the dial shield are small circular dials with hands – a time regulator with Arabic numerals, a melody switch with French inscriptions, a day of the week indicator with French names, and a current month indicator with names in French and Arabic numerals for the number of days in the month. In the arched part of the dial shield is the limb of the lunar calendar with Arabic numerals for the days. Inside the limb is a circular window showing the phases of the moon. Hour intervals are struck by hammers on a large bell, and the quarter hours are chimed with six hammers on six smaller bells. The music mechanism contains a carillon consisting of twelve bells and twenty-four hammers. The program carrier is a brass cylinder with pins. The set includes six cylinders, each containing two melodies. The number of the cylinder and the titles of the melodies encoded on it are engraved on the end sides:
• No. 1 Grenadiers March, Lelibuero
• No. 2 Room for a Rover, A Jigg
• No. 3 Old Woman Poor & Blind, A Minuet
• No. 4 The Dame of Honour, The Rummer
• No. 5 Amiable Vaingueur, The Conceit
• No. 6 A Trumpet, A Trumpet Minuet
The interchangeable cylinders are stored in a pull-out drawer inside the pedestal. The drawer opens from the reverse side of the case. The clock mechanisms are powered by three springs with three fusees. The clock features an eight-day winding and a spindle escapement with a pendulum on a spring suspension. The spring for the chiming mechanism is wound using a cord on the left side of the case, while a cord on the right side activates the chime. Included in the set are a winding key and a key for the doors.
