Note: The "Fusée Renversée" was invented by the French Academician Jean-Baptiste Le Roy, son of the celebrated Julien Le Roy and brother of the eminent Pierre Le Roy who was almost alone in using it. It was recorded in Mémoires de l' Académie Royale des Science for 1763, and was intended to balance the friction between the pivots of the fusee. hl the watch now offered for sale, it was more probably used in order to set the fusee in such a very thin movement. In the Cole's resilient escapement, invented in 1830, the actions of lock, lift and draw are the saine as though the teeth were shaped in dotted lises. The draw continues until the pallet strikes the inclined part of the tooth which serves as an elastic banking. A very similar movement by J.F. Cole was sold by Sotheby's on 19 June 1972, lot 182.
