A quarter-century after the launch of the first L.U.C Quattro timepiece in 2000, Chopard Manufacture celebrates the 25th anniversary of its Quattro movement by presenting a brand-new edition in ethical 18-carat rose gold, featuring a 39-millimetre case reshaped in line with the latest L.U.C aesthetic. A major innovation in the field of Haute Horlogerie, the exclusive Chopard Quattro technology has earned the L.U.C collection major recognition thanks to the first calibre powered by four series-coupled barrels stacked in pairs and containing exactly 1.885 metres of springs. This configuration – the only one of its kind in the world – enables an exceptional total power reserve of 216 hours (9 days), delivered with constant force to the escapement. The regularity of operation is ensured by a balance oscillating at a rate of 28,800 vibrations per hour, a guarantee of impeccable precision chronometer-certified by the COSC. Recognition by the Poinçon de Genève quality hallmark confirms the refinement of this L.U.C Quattro timepiece both technically and aesthetically.
