Established in 1775 by the horologist and watchmaker Abraham-Louis Breguet, Breguet is one of the oldest watchmaking manufactures in Switzerland. Breguet is best-known for his invention of the tourbillon, a watch escapement mechanism that helps in the improvement of time accuracy of a watch. Through the centuries, the brand has produced watches for numerous patrons including European royalties, Middle Eastern sultans, writers, composers and world leaders.
