For 20 years, Chopard Manufacture has been creating the watches in the L.U.C collection. This year at Baselworld 2016, Chopard is once again shaking up the classic codes of complicated Haute Horlogerie by introducing the new L.U.C Perpetual Twin, an all steel chronometer-certified perpetual calendar. The L.U.C Perpetual Twin is endowed with the mechanical excellence of Chopard complications while housing its perpetual calendar movement within a stainless steel 43 mm case.
