The clock is housed in a vertical wooden case of complex shape, finished in black lacquer and adorned with gilded moldings and openwork overlays. The tiered plinth stands on a gilded metal base with four protruding feet. The vertical ribs of the case are decorated with cast gilded hermae supporting a shaped cornice. On the front, an arched glazed door encloses the dial plate. Below the cornice on the lateral sides are shaped windows covered with openwork cast grilles; above the cornice are massive folding handles surrounded by openwork overlays. The top side of the case is fashioned as a vaulted dome with openwork overlays and a gilded pine cone on the summit, with similar cones mounted on the corners of the case. On the back of the case, a glazed door encloses the clock movement. The main dial is a silver chapter ring with minute divisions, two blued central hands, Roman numerals for the hours, and Arabic numerals near the five-minute intervals. Inside the ring are three winding arbors for the key, a shaped window with the master's name on a silver plate, and a square calendar aperture near six o'clock. In the corners of the square section of the dial plate are circular scales for a stopwatch, a days-of-the-week indicator, strike silent controls, and music controls. Inside the rings are painted female portraits symbolizing the four times of day—dawn, day, twilight, and night. The upper arched part of the plate is spanned by an arcuate scale with the names of twelve melodies and an indicator hand. Beneath the arch is a lunar calendar with a circular scale divided into twenty-nine and a half days. Inside the ring is a recess featuring a rotating sphere, one half of which is silvered and the other blue. The position of the sphere displays the phases of the Moon. The rotation axis of the sphere serves as the calendar indicator. The clock movement has an eight-day winding capacity, verge escapement, a pendulum, and three fusees—for the time, quarter strike, and the musical mechanism. The musical mechanism, with a cylinder, thirteen bells, and twenty-five hammers, activates every hour and consecutively plays one of the twelve melodies. A separate bell with a hammer serves for the hour and half-hour strike. Cords exiting through holes on the right and left sides of the case serve to activate the repeater and the musical mechanism. Visible through the glazed arched door is the backplate of the movement, adorned with engraving featuring the master's name “Roger Dunster”, along with the bells and the musical cylinder. The clock is mounted on a downward-tapering dark polished rectangular pedestal with a rotating top section.
