Many watchmakers researched the perpetual movement of a mechanism that, once set in motion, would continue to function indefinitely. But it was Abraham-Louis Perrelet who had the idea of harnessing the energy produced by the natural movements of the person wearing the timekeeper and, in 1777, developed the first automatic watch in the history of watchmaking. By placing the movement at the center of their development projects, the Perrelet engineers developed what was to become one of the mechanisms especially typical of the watch industry, the “Double Rotor.” This unique, patented creation represents the essence of Perrelet’s brand identity.
The Perrelet calibre P-181 with automatic winding displays two rotors, one on the dial side and the other on the side of the movement. The combination of the two perfectly synchronized rotors feeds the going barrel so the mechanism has a source of energy that is continuous and amplified. The rotor situated on the dial side also enables a constant control of the good functioning of the watch.
The cases with their fluid, dynamic lines—in steel, gold or titanium—house refined dials that are readily legible and display an attractive central motif. The Double Rotor becomes mobile and turns on its own axis at the slightest movement, as when worn on its owner’s arm. Calibre P-181 can appear to be both technological or poetic, and sportive or classical. The Double Rotor is represented in four different families of Perrelet Watches: Turbine, Diamond Flower, Double Rotor Titanium and Classical.
The latest creation is the surprising Turbine. This is certainly the most dynamic interpretation of the Double Rotor, since it completely covers the dial. Consequently, the Turbine, whose design is protected, produces a spectacular optical effect by means of a lower dial. It is an effect which, only on this model, is reinforced by the exceptional dissociation of the two rotors.
