Breguet’s archives, kept in Switzerland and in Paris, record the developments that have sustained Breguet watchmaking for more than two centuries. Today Breguet watches are made in the Vallée de Joux, the centre of advanced mechanical horology. The Breguet workshops bring together extraordinary resources to handle the essential aspects of watchmaking. Driven by the same enthusiasim that A.-L. Breguet brought to his art, craftsmen work daily to perfect the timepieces that earn Breguet its position as the architect of fine horology.
