Breguet

Abraham-Louis Breguet spearheaded a number of inventions, including the over-coil hairspring and the tourbillon, which he first invented in 1795 and patented in 1801. It is no coincidence that he remains the most cited reference point for accomplished watchmakers centuries later, from George Daniels to François-Paul Journe.
