Perrelet Watch Turbine XL. A1051/1.  Recognised as the most distinguishing design from the brand, the Perrelet Turbine XL watch collection is inspired by the double rotor movement that displays an oscillating weight positioned on the front of the dial. This propeller style finish draws its aesthetic from the field of aeronautics and the breathtaking visuals that show when you move your wrist are mesmerising.  The bold 48mm stainless steel and black PVD case of this Perrelet Turbine XL watch embraces the P-331 automatic movement that was made completely in house by the brand. The striking black turbine rotor defines the model and spins captivatingly over a matching black under dial while the Arabic numerals and propeller styled hands are decorated in a luminous paint. To complete the watch, a black rubber strap is added alongside a matching stainless steel and black PVD clasp.
