30 mm, automatic, ethical rose gold, Lucent Steel™, diamonds. The Happy Sport collection is the emblem of Chopard’s creativity and boldness. Its playful, free-spinning gems, dancing between two sapphire crystals, 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 with a mechanical movement featuring an automatic winding mechanism specially developed for feminine cases.
