Entirely designed, developed and produced by Chopard Manufacture, this mechanical hand-wound L.U.C Calibre 04.01-L also bears the imprint of the passion for motor sports nurtured by Karl-Friedrich Scheufele. Inspired by the mechanical beauty of cars, its design echoes that of an engine block. To protect it from vibrations, it is mounted on silent blocks. Its tourbillon, equipped with an aluminium carriage and a balance spring with Phillips terminal curve, ensures extreme precision guaranteed by the Swiss Official Chronometer Testing Institute (COSC). In addition to the hours and minutes, it displays the small seconds directly on the tourbillon carriage and has a power-reserve indicator at 12 oclock.
