Notes

Although it was made after the death of Louis Berthoud, under the direction of his pupil Henri Motel, the movement of this chronometer is identical to that produced by the eminent maker as early as 1800.This chronometer is mentioned by J.-C. Sabrier in La Longitude en mer à l'heure de Louis Berthoud et de Henri Motel, Antiquorum Editions, Geneva, 1993, p. 184.This chronometer was previously in the Léon Leroy Collection as attested by the sticker inside the cover.
