Perrelet celebrates the 20th anniversary of its emblematic Double Rotor by raising this fundamental invention to fresh peaks of refinement. Issued in limited series of 250 for its steel version, and 77 for the pink gold variation, the First Class Double Rotor Skeleton anniversary collection combines the watchmaking genius of this automatic winding system with the art of skeleton-working. Thanks to this ingenious alliance, the openworked dial enables the eye to travel into the heart of the mechanism, lulled by the natural rhythm of the second rotor. The pink gold Double Rotor features a new design with a Côtes de Genève finish and a special engraving to mark this jubilee. Loyal to the original model, the Manufacture Perrelet P-481 calibre has maintained the visible ruby in its centre to give a lively touch to this creation. Embodying a new generation of timepieces, this collection exudes a fascinating creative audacity while remaining firmly attached to the fundamental values of the House of Perrelet.
