Only two other clocks of this type are known to exist, one in a Swiss private collection, the other in the Musée International d'Horlogerie in La Chauxde- Fonds. The clock is exceptionally well-made, the double barrel and double fusee arrangement for the music assuring long duration. The heavy, compacted brass movement is typical of Jaquet-Droz, the case is also exceptionally well made. During this period Jaquet-Droz was the only maker in Switzerland producing complicated musical clocks.
