Chopard presents two new versions of its L.U.C Perpetual Twin: one in steel, with a blue dial, and one in 18-carat rose gold, a material used for the first time on this model, with a grey dial. Visible through the sapphire caseback is the self-winding mechanical movement, L.U.C. 96.22-L calibre, with an integrated 22-carat gold micro-rotor, which has made it possible to keep the thickness of the entire mechanism to just 6 mm, and two barrels to ensure a 65-hour power reserve. This same movement has been chronometer-certified by the Contrôle Officiel Suisse des Chronomètres (Cosc), a guarantee of maximum precision and reliability.
