The tourbillon is one of the most emblematic complications there is and remains closely linked to the Maison Breguet, since it was invented by Abraham-Louis Breguet. For the Tradition 7047, this invention is paired with a fusee-chain system designed to optimise the rate regularity of the watch by ensuring constant torque, whatever its winding level is. This manually-wound watch is also subject to a patent application concerning its power reserve: indicated at 10 o’clock, it features a reducer differential allowing it to be displayed on the barrel drum.
