True to the Manufacture's commitment to certified precision, the Chopard 01.15-C self-winding movement, beating at the heart of the Alpine Eagle Summit luxury watches for men and visible through a transparent sapphire crystal caseback, is developed in Chopard's watchmaking workshops and certified by the Official Swiss Chronometer Testing Institute (COSC). When fully wound, the mechanism provides 60 hours of power reserve. From gold smelting to bracelet manufacturing, along with gemsetting, component production and movement assembly, every stage in the making of this Swiss watch collection is performed by Chopard's Artisans of Emotions.
