The Bordier brothers were established watchmakers by 1794; by 1815, they were involved in the creation of the Grand Mézel. In 1794, they formed a partnership with Roux and Romand, founding the company Bordier, Roux, Romand & Cie. From 1794 to 1811, they focused on producing self-winding repeater watches and intricate skeleton perpetual calendar watches, often adorned with enamel paintings, pearls, and precious stones.
