The design for this exceptional clock is a variation on an eighteenth century model attributed to the fondeur-ciseleur François Vion, which depicts the Three Graces, possibly after Falconet, entwined and supporting a sphere containing an orbit movement. The model by François Vion, is thought to have been initially designed around 1765 and is first recorded as having been delivered by the marchand-mercier Simon-Philippe Poirier in 1769 to Madame Du Barry at the Château de Versailles. This clock is now in the collection of the Louvre and is illustrated in P. Verlet, ‘Les Bronzes Dorés Français du XVIIIe siècle’, 1987, p.261 (ill. 296), and p.279 (ill. 308-310).

However it is interesting to note that the original by Vion was the base of inspiration for the current design by Henri Dasson. Dasson presented this model at the 1878 Paris Universal exhibition then in Moscow in 1891. A similar clock dated 1887 by acquired by Cornelius Vanderbilt for his London Hyde Park mansion
