Robert Osmond, maître-fondeur en terre et sable in 1746 and appointed juré des fondeurs in 1756, often signed his pieces. Influenced by the bronzier Caffieri, Osmond was one of the first to interpret the new neo-classical style. His work was much in demand among sophisticated collectors and aristocratic patrons. As a result, his atelier flourished in the early 1760s. Assisted by his nephew Jean-Bapiste Osmond, maître-fondeur in 1764, who succeeded him on his death in 1789, the Osmonds included most of the avant-garde elite of French society amongst their clients.
The design of the present clock is No.110 in Osmond's Livre de Desseins of 1775, now housed in the Bibliothèque Doucet, Paris (H. Ottomeyer/P. Pröschel et al., Vergoldete Bronzen, Munich, 1986, vol.I, p.228.)
Elie Barbezat, émailleur en cadrans, settled in rue Bertin Poir and flourished from 1768-1776. His dials appear on clocks by Peignat, Robin and Ragot.
Denis-Francois Dubois was appointed maître in 1767. During the period 1772-1778 he is recorded at premises in rue des Cordeliers.
