The Finest French Pendulum Clocks presents an illustrated history of French pendulum-clocks, between the time of Louis XIV and the Empire, through their stylistic evolution. It is far from easy to distinguish between a real 18th century clock and a 19th century imitation, properly estimating its commercial value, to which contribute the beauty of the decoration, the quality of materials, the presence of the original clockwork, the state of conservation, the rarity of the piece and its artistry.
