Notes

This watch is considered as a commemorative watch as it seems to be a tribute paid to his father Julien Le Roy, when Pierre was awarded in 1770 the double prize of the Académie Royale des Sciences, for the best method of finding the longitude at sea. An identical watch No. 4540, is described and illustrated by W. Posner in Antiquarian Horology, June 1970, cover and pp. 431-432 (an off-print copy is coming with the watch).
