Notes
Lépine was the first maker in France to use Arabic numerals for the hours in place of the traditional Roman chapters. This watch
is a good example of this new style of dial.
Jean-Antoine Lépine (1720-1814).
He was born on 18 November 1720 at Challex, a small village a
few kilometers north of Geneva. After having worked for some
time at the establishment of Decrose, at the Grand Saconnex in
the suburbs of Geneva, he arrived in Paris in 1744. A workman
for André Charles Caron, King's Clockmaker, he married his
employer's daughter in 1756 and was received Master in 1765.
He was appointed "Horloger du Roi" (King's Clockmaker)
about 1765. In 1766 he succeeded Caron, and appears on the
list of Paris clockmakers of that year as: Jean-Antoine Lépine,
Hger du Roy, rue Saint Denis, Place Saint Eustache. In 1772,
Lépine established himself in the Place Dauphine, in 1778-
1779, Quai de l'Horloge du Palais, then in the rue des Fossés
Saint Germain l'Auxerrois near the Louvre in 1781, and finally
at 12 Place des Victoires in 1789. In 1782, his daughter Pauline
married one of his workmen, Claude-Pierre Raguet, with whom
he formed a partnership in 1792. In 1763 he invented a new
repeating mechanism for watches, which was published in
the Mémoires de l'Académie des Sciences in 1766. His new
caliber, of a revolutionary conception, replacing the rear plate
by bridges, was invented about 1770. The different moving
parts could thenceforward be dismounted separately, which
made maintenance and repair much easier. Also, the use of a
dead-beat escapement, less sensitive to variations in the driving
force than the recoil escapement hitherto in use, allowed him to
suppress the fusee. This new layout was improved by Breguet
who adopted it from 1790 for most of his watches. Lépine was
responsible for a number of other inventions, one of them
being the virgule escapement, a simplification of the double
virgule escapement invented by his father-in-law and used by
his brother-in-law Pierre Augustin Caron (who became famous
under the name of Beaumarchais). He also developed a new
form of case, ?à charnières perdues? (with concealed hinges)
and a fixed bezel. Lépine remained faithful to his country of
origin, and went often to the Gex countryside, more particularly
to Ferney where Voltaire had set up a watch manufactory in
1770. Friendly relations were established between Lépine and
the philosopher, and though we do not know the exact role he
played in the Ferney manufactory, it seems that he had a hand
in its organization. It is certain that he gave commissions to
the workshops there until 1792. An unsigned memoir of 1784
reports that Lépine stayed in Ferney for 18 months, and that he
had watch movements made there to a value of 90,000 livres a
year. After his retirement in about 1793, although he had lost his
sight, Lépine continued to be active in the firm managed by his
son-in-law, and this until his death on 31 May 1814,at the age of 93.
