The design of the present clock may be compared to the 'audience clocks' of Antide Janvier, with their simple mahogany cases raised on recumbent ormolu lions and sphinxes. Tardy (p.381) refers to the 'retour d'Egypte' in connection with this model and clearly it is influenced by the popular Egyptian revival style made fashionable after Napoleon's expeditions to Egypt. Roberts (p.93) shows a fine skeletonized table regulator signed Baltazar, dating from circa 1800, and probably this is the same maker as the present clock. A Baltazar is recorded in Pont Saint Michel in 1800 and another, his son, in Rue de la Calandre in 1806; this clock is presumably the work of the former.
