The Oudin dynasty of watchmakers begun with Charles Oudin, a renowned watchmaker and student of Breguet, who established his workshop in Paris at the Palais Tribunat in 1804, then at the Galerie de Pierre from 1810-20. He was succeeded by his son Jean-Charles and Jean-Charles's cousin Joseph Oudin. The house of Oudin specialized amongst others in finely enamelled and jewelled watches, snuff boxes with watches and form watches.
Philippe Prochietto, called Prochet, (Geneva 1825-1890), was a pupil of the renowned Swiss enamel painter G. Lamunière. Prochietto was himself known as an excellent enamel miniature artist who often worked for the famous gold box maker Charles Bruguier. Besides portraits he painted on enamel very fine copies after Old Masters. Examples of his work can be seen in the Musée des Arts Décoratifs in Geneva.
