The new Breguet Classique Double Tourbillon ref. 5345 ‘Quai de l’Horloge’ blends mechanical virtuosity with aesthetic mastery. Entirely visible, the movement reveals two tourbillons that set the whole plate in motion through a central differential. Each component is hand-finished, while the back of the movement is engraved with the “House on the Quai”, the Parisian building where Abraham-Louis Breguet fulfilled his life’s work. Like a delicately chased sculpture, the entire exposed mechanism pivots around its axis at the rate of one full turn every 12 hours.
