Breguet was founded in 1775 by Abraham-Louis Breguet, a Swiss watchmaker born to Huguenot parents in Neuchâtel. He studied watchmaking for ten years under Ferdinand Berthoud and Jean-Antoine Lépine before setting up his own watchmaking business at 51 Quai de l'Horloge on the Île de la Cité in Paris. On 26 June 1801, the tourbillon was patented by Abraham-Louis Breguet. He conceived the idea of a new type of regulator called "the Tourbillon", around 1795. The French Interior Minister granted Breguet a patent which would last for a ten year period for his invention. Breguet creates the most complicated pocket watch ever created for Marie Antoinette. The self-winding watch includes a minute repeater, a full perpetual calendar, the equation of time, a power reserve indicator, a metallic thermometer, an on-command independent seconds hand, a small sweep seconds hand, a lever escapement, a gold Breguet overcoil and a shockproofing. It has been likened to shrinking a cathedral clock into a pocket watch. Unfortunately, it would take 44 years to create this elaborate timepiece—it had to be finished by Abraham-Louis Breguet’s son—and Marie Antoinette would never live to see it. She was beheaded during the French Revolution on October 16, 1793. 1812: Breguet created the first wristwatch for the Queen of Naples. Officially begun in 1810, the ultra-thin repeating watch, which was oval in shape, came equipped with a thermometer and was the first watch to be mounted on the wrist. Its bracelet was made of hair entwined with gold thread.
