This new rendition of the L.U.C XP makes great show of its curvaceous form, with a steel case paired with a silvered dial featuring vertical satin-brushing and large blue numerals. The original, automatic movement – calibre L.U.C 96.53-L – owes its extra-thin 3.30-mm silhouette to a micro-rotor in tungsten. It delivers a power reserve of almost 60 hours, thanks to the two stacked barrels of Chopard's Twin Technology. The end result is a watch measuring a sleek 7.20 mm high that's simply styled and brilliantly up-to-date with the perfect dash of classic charm.
