When he invented the revolutionary automatic self-winding movement in 1777, Abraham-Louis Perrelet could have sat back and rest on his laurels. But he did far from it. His intense passion for the art and science of watchmaking led him to more remarkable patents such as the Perrelet Double Rotor mechanism. Encased in a sleek tonneau or round-shaped stainless steel, gold, or titanium case, it had been interpreted into four versions: the stunning turbine, the lotus themed Diamond Flower, the Titanium, and the Classical collection. The Perrelet Double Rotor has a display caseback showcasing the automatic movement and measures 35mm to 43.5mm with an impressive reliability assured by a 40hr-42hr power reserve. A profound example of fine watchmaking, the Perrelet Double Rotor heralds the time and date in the most innovative way possible.
