This new Pilo & Co Genève Pièce d'Exception PW01 is inhabited by a movement called Calibre Manufacture Maison PW01, a mechanical self-winding movement with 27 rubies vibrating at 28,800 vibrations per hour (4 Hertz). This exceptional timepiece is the perfect reinterpretation of a micromechanical package of simple complications in the "watchmaking of the fundamentals" mode: Day-Date (day and date indication), GMT (second time zone) and a 40-hour power reserve indicator. Pure chronometry with a Côte de Genève finish, driven by a deep black oscillating weight and encased in a 44 mm diameter case.
