Stamped with the famous Geneva Seal – a sign of quality crafting in the respect of watchmaking tradition –, the hand-wound L.U.C 02.14-L movement is equipped with two barrels that are superimposed and doubled in series. This patented Quattro® technology offers an autonomy of more than 9 days (216 hours) and a constant power regularity that enables this Imperiale Tourbillon model to fulfill all the criteria required to obtain the certificate issued by the Contrôle Officiel Suisse des Chronomètres (COSC). It reveals the hours, minutes and small seconds on the 1-minute tourbillon at 6 o’clock and a power reserve indicator magnificently brought to the forefront at 12 o’clock within a circular arc set with diamonds and amethysts.
