Breguet is a Swiss 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 developed into a practical solution by Abraham Breguet in 1801, after having been invented by his friend John Arnold. Abraham Breguet also invented and produced the world's first self-winding watch in 1780, as well as the world's first wristwatch in 1810.

Abraham-Louis Breguet, born in Neuchâtel, then a Prussian principality, was a horologist who made many innovations in the course of a career in watchmaking industry. He was the founder of the Breguet company, which is now the luxury watch division of the Swiss Swatch Group.
