In 1794, they took Roux and Romand into partnership, establishing the company Bordier, Roux, Romand & Cie. Between 1794 and 1811, they were specialised in automaton repeating watches as well as complicated or skeletonised watches, with perpetual calendar, often decorated with painted enamels, pearls and gemstones.
