An identical clock to the present example was sold, Christie's London, Property of the late George Field Esq., June 12, 1893, Lot 80 for 199gns. 10s. to Wertheimer and then passed into the Greenberg Collection, New York. That particular clock is illustrated in French Clocks op. cit.. The calendar dials of these two clocks are both virtually identical, the present example is signed and dated by Joseph Coteau, Paris 1774 and is a very fine example of what was the best enamelling in the world.
