A testament to Chopard Manufacture's perfect mastery of Haute Horlogerie, the L.U.C. Chrono One in 18-carat rose gold is powered by the chronometer-certified L.U.C Calibre 03.03-L, comprising a complication which is the most complex to produce: a fully integrated chronograph with a column-wheel system, visible through the bevelled transparent case back.
