Abraham-Louis Breguet or Br̩guet (10 January 1747 Р17 September 1823), born in Neuch̢tel in Switzerland, made many innovations in the course of a career in watchmaking in France. He studied watchmaking in France and in England and invented different escapement methods, including the tourbillon, and re-winding mechanisms. His watches and clocks are widely regarded as some of the most beautiful and technically-accomplished.
