Breguet is a Swiss-French luxury watch, clock and jewelry manufacturer founded by Abraham-Louis Breguet in Paris in 1775. Since 1999, it has been a subsidiary of the Swiss Swatch Group. Headquartered in L'Abbaye, Switzerland, Breguet is one of the oldest surviving watchmaking brands and a pioneer of numerous watchmaking technologies such as the tourbillon, which was invented by Abraham Breguet in 1801. Abraham Breguet also invented and produced the world's first self-winding watch (the Perpétuelle) in 1780, as well as the world's first wristwatch in 1810 (the Breguet No.2639, for Caroline Bonaparte, Queen of Naples). Breguet is a highly regarded watch manufacturer. Over the years, notable Breguet patrons and timepiece owners include King George III, Queen Victoria, Alexandre I of Russia, Napoléon Bonaparte, Ettore Bugatti, Sir Winston Churchill, Sergei Rachmaninoff, Gioachino Rossini, Arthur Rubinstein and so on. In particular, the Breguet & Fils, Paris No. 2667 (1814) pocket watch ranks as one of the world's most expensive watches ever sold at auction, fetching US$4.69 million (CHF 4,339,000) in Geneva in May 2012. The Breguet Sympathique Clock No.128 & 5009 (Duc d'Orléans Breguet Sympathique), on the other hand, currently holds the title of the most expensive Breguet timepiece ever sold at auction, fetching US$6.80 million in New York in December 2012.
