Breguet is a Swiss watch manufacturer founded by Abraham-Louis Breguet in Paris in 1775, headquartered at L'Abbaye in the Vallee de Joux and owned by the Swatch Group since 1999. Its principal collections are the Classique, Tradition, Marine, Type XX, Reine de Naples and Heritage. Abraham-Louis Breguet patented the tourbillon in 1801 and delivered what is regarded as the first wristwatch in 1812 to Caroline Murat, Queen of Naples. The guilloche dial, the blued-steel Breguet hand and the Breguet overcoil are all his inventions and remain industry standards.
