Perrelet First Class Double Rotor & Double Rotor Skeleton
This autumn, Perrelet is enriching its First Class line with two new collections: First Class Double Rotor and First Class Double Rotor Skeleton.
The Double Rotor technology is in the limelight with these timepieces featuring a stainless 42.50 mm-diameter case with pure, sleek lines enhanced by the signature Perrelet fluted pattern on the side. While remaining true to the design of the First Class collection, Perrelet has chosen to subtly evolve the patented Double Rotor concept that has forged its success. The latter, adorned with a “Côtes de Genève” pattern, takes an even larger place on the grained/guilloché white or black dial of the First Class Double Rotor model, or openworked black or white guilloché of the First Class Double Rotor Skeleton. The blued hands lend a touch of color to the purity of the dials, as does the 26th movement jewel elegantly revealed in the center.
In 1995, Perrelet introduced the first Double Rotor P-181 caliber with automatic winding via an oscillating weight. It represented a technical feat in that the mechanism draws its energy from two rotors. The first, referred to as the oscillating weight, is placed under the movement, while the second, known as the upper rotor, is sited at dial level and provides an opportunity to observe the automatic winding function. The perfectly synchronized rotation of the two rotors powers the barrel, thus providing the mechanism with a constant supply of energy. This device ensures winding that is faster, more stable and more efficient than with a classic system.
The First Class Double Rotor is powered by the Double Rotor P-181-H caliber, the first entirely in-house manufactured Double Rotor movement. It is distinguished by its date at 6 o’clock that is visible when the Double Rotor is in action. Perrelet also innovates with the Double Rotor Skeleton P-481 movement, the first to associate the Double Rotor with a manufacture-made skeleton caliber. Both models, equipped with a movement beating at a frequency of 28,800 vph (4HZ) have a 42-hour power reserve. The First Class Double Rotor and Double Rotor Skeleton models are fitted with a brown or black alligator leather strap equipped with a steel folding clasp.
