Perrelet First Class Double Rotor Skeleton

Perrelet introduced its double rotor watches in 1995, and this year it is presenting the First Class Double Rotor Skeleton for its 20th anniversary. The dial-side rotor is connected to the oscillating weight on the caseback side; it has a practical function because the total mass of the rotors is higher and so increases the amount of energy provided to the barrel. But this double rotor is principally a method of making the dial side of the watch more spectacular by displaying the automatic winding function, analogous to the beautiful Jaeger-LeCoultre Master Ultra Thin Minute Repeater Flying Tourbillon with peripheral rotor visible through windows in the dial, and the Dior VIII Grand Bal Fil de Soie with its dialside openwork rotor.

The First Class Double Rotor Skeleton has an in-house skeleton-worked movement, the Calibre P-481, in a 42.5-mm case, thickness 10.7 mm, in stainless steel or 18-karat rose gold. The case has a 50 metre water resistance. The dialside rotor has a new design with Côtes de Genève finish and the pivot jewel in view at the centre. The watch has a sapphire caseback, and an alligator leather strap with folding clasp.
