Charles Oudin, a talented and innovative watch and clockmaker, was a student of Abraham-Louis Breguet. Oudin excelled in creating watches with the Equation of Time feature and developed a version of this complication that could be integrated into Breguet’s souscription watches. By 1805, he had established his workshop at the Palais Royal, Galerie de Pierre. In 1819, one of Oudin’s Equation of Time watches was showcased at the Paris Exhibition.
