Abraham-Louis Breguet (1747-1823), set the standard by which all fine watchmaking has since been judged. His career started with a series of breakthroughs: the development of the successful self-winding perpétuelle watches, the introduction of the gongs for repeating watches and the first shock-protection for balance pivots. He later went on to invent the Tourbillon which was patented in 1801. Today, Breguet still make each watch as a model of supreme horological art.
