Calibers produced by Breguet (Switzerland)

Breguet is a Swiss luxury watch, clock and jewelry manufacturer founded by Abraham-Louis Breguet in Paris in 1775. 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. 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). Since 1999, it has been a subsidiary of the Swiss Swatch Group.
