Chopard enriches its range with a barrel-shaped chronometer in 18k rose gold, designed like an exceptional wine, leaning on the best of Chopard watch-making expertise. Ultra-thin, gracefully curved and displaying rare elegance, the L.U.C Heritage Grand Cru is one of few tonneau-shaped watches to have an automatic winding movement of the same shape, the L.U.C 97.01-L. It is a reference to the pocket watches created by Louis-Ulysse Chopard. Just as a grand cru wine is classified and certified, the excellent craftsmanship is anointed with the Geneva Seal and its chronometer-grade precision by the COSC. Fitted with Chopard's Twin technology, it offers a comfortable 65 hours of autonomy. Unique in many ways, the L.U.C Heritage Grand Cru is for the distinguished man who collects great wines and exceptional watches: a true modern-day epicurean, the contemporary Chopard gentleman.

Fully developed, produced and assembled in the Chopard Fine Watchmaking workshops, this COSC-certified chronometer, the self-wound L.U.C 97.01-L mechanical movement, is the first tonneau-shaped caliber developed by the Chopard Manufacture in 1997. It oscillates at a rate of 28,800 vibrations per hour (4 Hz) and offers a 65-hour power reserve thanks to Twin technology, a system invented by Chopard that combines two coaxial barrels and represents a particularly remarkable technical feat in light of the extreme slenderness of its 3.3 mm-thick movement. This movement is wound by a micro-rotor in 22-carat gold.
