Lot Essay

Mugnier le Jeune
Son of Mugnier l'Ainé, Parisian watchmaker working for Abraham-Louis Breguet (1747-1823).
Mugnier le Jeune is Horloger de l'Empereur (Watchmaker of the Emperor), Napoleon I (1769-1821), Emperor of the French (1804-1815), then Horloger de S.A.R. Monsieur frère du roi (Watchmaker of HRH the King's brother), the future Charles X (1757-1836), King of France and Navarre (1824-1830).
When he signed "Horloger de S. M. I. et R." or "Horloger de LL. MM. II. et RR." this referred to Horloger de Sa Majesté Impériale et Royale (Watchmaker of His Imperial and Royal Majesty) or Horloger de Leurs Majestés Impériales et Royales (Watchmaker of their Imperial and Royal Majesties), title given to Napoleon I and his wife. He created several extraordinary watches with automatic winding and various other watch complications (see: Sabrier, Jean-Claude, La montre à remontage automatique, XVIIIe - XXIe siècles, Paris, Editions Cercle d'Art, 2011, pp. 112-115). The watches known by Mugnier are all in the vein of the best accomplishments of Abraham-Louis Breguet.
A certain Lepinte succeeded him in 1840. He was active until around 1850.
