Hubert Sarton (1748-1828) was Belgium's greatest clockmaker and is renowned for his fine multi-dial skeleton clocks. Born in Liège, he was apprenticed to his uncle, DieudonnÃ© Sarton, in 1762 and by 1768 was working at Pierre Leroy's workshop in Paris. In 1772 Sarton was appointed Court Mechanic to Duke Charles Alexander, Prince of Lorraine. He was commissioned to make several clocks for the Duke, including a superb example with moving dial (The Albert Odmark Collection).
An identical clock is depicted and discussed in Jaques Nève's 'Les Pendules d'Hubert Sarton, 1748-1828, Horloger - Mécanicien, Inventeur', pages 84/85/86.
A world time skeleton clock of very closely related design and signed Sarton is also illustrated in Derek Roberts, Continental and American Skeleton Clocks, Schiffer, 1989, page 178.
