TTR3 Perfect chronometry
3Volution: Perfect TimekeepingBy mounting three independent tourbillons inside a large mobile cage, Antoine Preziuso has achieved a tour de force that Breguet himself would have admired.
The hand-winding mechanism of the 3Volution winds a twin barrel that ensures optimal efficiency and a comfortable power-reserve. The last wheel and pinion of the gear-train drives the heart of the system: a circular roller carrying no fewer than three flying tourbillons equidistant from the centre of the roller, with their respective axes forming an equilateral triangle. Each of the three tourbillons performs a complete rotation around its axis in one minute, while the entire roller needs only 2 minutes 15 seconds to complete one revolution. The speed of rotation of each of the tourbil-lons, which constitutes the first factor in enhancing precision, is accelerated by this double revolu-tion. The respective frequencies of the three regulating organs keep step with each other thanks to the resonance achieved by the flange around the circumference of the roller that acts as a resona-ting chamber.
The main principle of the physical phenomenon of resonance is that each oscillator moves in har-mony with the other two in a self-compensating manner, with the three oscillators vibrating at an average, stable and virtually imperturbable rate. Another consequence is that the amplitude of each oscillator is significantly increased when there is resonance.
It all adds up to attaining truly perfect timekeeping precision for the first time in the history of the wrist-watch.
