For BaselWorld 2013 Perrelet presented the first chronograph version in its Turbine collection. The distinctive double rotor that gives the watch its name, visible through apertures in the dial, are undisturbed by the addition of the chronograph complication thanks to an innovative 60-minute counter located on a central sapphire disc. The 47mm model is available in stainless steel or pink gold with DLC accents on the bezel ring and is powered by the P-361 chronograph calibre.
