    Note: The ultra rare escapement used in this timepiece was the invention of Robert Robin (1742-1809). Robin was the horologist to Louis XV and this escapement was supposed to combine the advantages of both the lever and chronometer detent. Research shows that in 1695 Louis XIV repealed the Edict of Nantes, driving the Huguenot family of Lesquereux from France. They settled in Fleurier in the Canton of Neuchatel. In the early 1800's V. Aime (husband of Marie Anne Lesquereux) was a manufacturer of watch spring employing 4 or 5 workmen. A son, Leo was born in 1806. Leo made life long friendships with two famous horologists, Arnold Henry Guyot and Auguste Agassiz. L. Lesquereux & Son were working in Columbus, Ohio. Records show that among customers of Borel & Courvoisier was Léon Lesquereux, junior, with his father, the famous botanist and geologist. While the father pursued his scientific work, the son built up an important trade in watches.
