Entirely developed, produced and assembled at the Chopard Fine Watchmaking workshops, and chronometer-certified by the COSC, the manually wound mechanical movement L.U.C 03.10-L beats to a frequency of 28,800 vibrations per hour (4 Hz) and possesses a 60-hour power reserve. The superb hand-finishing of the movement’s components and its exceptional watch performances have enabled it to obtain the Poinçon de Genève, and its precision is confirmed by the Chronometer certificate, issued by the COSC. In addition to displaying the hours and minutes, and the small seconds on the precision moon phase, the watch is equipped with a column wheel and a perpetual calendar that shows the days and a 24-hour counter at 9 o’clock, the months – taking into account leap years – at 3 o’clock, and a large instant date display at 12 o’clock. It features a semi-instantaneous jumping minute counter. It shows the hours and minutes at the center and the small seconds at 6 o’clock with the precision and elegance that characterize Chopard.
