Charles Oudin, pupil of Breguet and one of his best foremen, devised the equation of time to fit the ‘Montres de souscription’. He was established in business on his own behalf in the Palais Royal, Galerie de Pierre from circa 1804 to 1825, was succeeded by his son who transferred the firm to Galerie Montpensier 1830-1840 and subsequently took Detouche into partnership. A. Charpentier was successor to Oudin Fils, son of Charles, with the signature: ‘Charles Oudin à Paris, Horloger de L.L. M.M., l’Empereur et l’Impératrice de Russie’. To accompany the display at the 1862 Exhibition in London, Oudin-Charpentier produced a book entitled: ‘Catalogue of Chief Exhibits by Oudin-Charpentier, principal clockmakers to their Majesties the Queen and King of Spain and to the Imperial Navy’. Considering the quality of Oudin’s work, it is surprising so little is recorded about his life.
