The Happy Sport women's diamond watch collection is the emblem of Chopard’s creativity and boldness. Dancing between two sapphire crystals, the playful, free-spinning gems of this green mother-of-pearl and diamond watch have captured the imagination since 1993, when Chopard became the first Maison to combine steel and diamonds. Its watchmaking expertise has enabled Chopard to equip the Happy Sport 30 mm green mother-of-pearl and diamond watch with a mechanical movement with automatic winding specially developed for feminine cases. Little Diamonds Do Great Things.
