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