Watchmaker Abraham-Louis Perrelet was a watchmaker extraordinaire in the 1770s. In 1777, he invented the automatic movement that works via a rotating rotor—the basis for all automatic watches today. Perrelet was re-established in the late 20th century, and in 1995 released its Double Rotor caliber with two rotors, one on the dial side. That was followed by the Turbine model four years later, which has become another signature for the Perrelet. The watch features turbine-like blades and a lower dial spins around revealing itself through the blades.
