The L.U.C XP Tonneau in white gold displays the hours, minutes, small seconds, and a date shown through a window at 6 o’clock. All these functions are driven by the ultra-thin, self-winding L.U.C. Calibre 3.97. Entirely designed, developed, fine-tuned and produced in-house, this movement is a mere 3.30 mm thick – a technical detail that incorporates an off-centred micro-rotor and a double barrel (based on patented Chopard Twin® technology) supplying an over 65-hour power reserve.
Chronometer-certified by the COSC, the movement follows the contours of the case housing it – a rare distinctive feature matching the demands of Haute Horlogerie. The L.U.C 3.97 proprietary movement can be admired through the sapphire crystal case. The slender, slightly curving case makes a perfect fit on the wrist and is available in 18-carat rose or white gold with satin-brushed and polished finishing.
