In 2015, 20 years after its launch, Perrelet is celebrating the anniversary of its emblematic Double Rotor concept.
In 1995, as a tribute to Abraham-Louis Perrelet, inventor of the automatic movement in 1777 and to perpetuate a longstanding tradition of avant-garde horology, the Perrelet watchmakers presented the first Double Rotor P-181 caliber automatically wound by an oscillating weight and stemming from more than five years of research and development. From a technical standpoint the Double Rotor constituted a major watchmaking breakthrough, since the mechanism derived its energy from two rotors.
With the First Class Double Rotor Skeleton, equipped with an in-house manufacture movement, Caliber P-481, Perrelet associates the horological tradition of its innovative Double Rotor concept with its skeleton-work expertise.
