Notes

Although signed "Julien Le Roy", this watch was made by his son Pierre after his death (the cock pierced and engraved "J.L.R." was used by Pierre Le Roy after the death of his father). The invention of the fusée renversée '-vas due to Jean Baptiste Le Roy, the second son of Julien and a member of the Académie Royale des Sciences. The invention is recorded in Mémoires de l'Académie Royale des Sciences for 1763. See Ch. Allix and G. Brusa : Antiquarian Horolo, y, June 1968 and June 1972 in which the watch is described and illustrated.
