The watchmaker François Ducommun-dit-Boudry (1763-1839) came from an internationally renowned family of watchmakers in La Chaux-de-Fonds. His father, Abram Ducommun (1723-1797), was a master watchmaker specializing in the manufacture of planetariums and his maternal grandfather, Josué Robert (1691-1771), was the royal court watchmaker of the Prussian King Frederick William I (1688-1740).

Nine such astronomical pendulums are known to date: Three are in private collections; one in patinated bronze, in the Museum of Applied Arts in Milan; another one, but with a brass case, is in the Beyer Clock Museum in Zurich, and three are in the collection of the Musée international d'Horlogerie de la Chaux-de-Fonds, one of which is identical to the one on offer, except for a few details.
