Indisputably, Abraham-Louis Breguet is one of the most important watchmakers of all times. Many of his patents are in use this very day. The master set up his workshop in Paris in 1775. As a respected person at court—at a later time by the imperial family of Napoleon—he succeeded with a whole number of masterpieces. Among other things, he invented the tourbillon and the gong spring for repeating watches. His heirs carried on the family’s legacy. To this day, watches are manufactured that are committed to the famous tradition of Brequets horology. The best known models among these are: Grande Complication, Aeronavale Type XX, Heritage, Flying Tourbillon, Marine and the Classique series.
