In 1976, Ronald Kurowski, a talented Chopard designer, became fascinated with the sparkle of unset diamonds. A dream was born: that of creating a watch where diamonds could enjoy total freedom of movement. The dream was to become reality in the shape of «Happy Diamonds» an innovative concept allowing diamonds to move freely thanks to a dial inserted between two sapphire watch crystals. Originally the first “Happy Diamond” was a model for men but it then inaugurated a new watch collection designed for women.
