Introduced in 2007, the Ballon Bleu de Cartier is known for its rounded case and signature cabochon crown set within a protective arch, creating the look of a floating blue bubble. Designed for both men and women, it comes in steel, gold, or diamond-set versions, with quartz or automatic movements. With Roman numerals, blued-steel hands, and water resistance up to 30? metres, it’s a soft yet striking Cartier icon. Presented on a robust steel bracelet, it features a 36mm case and is water-resistant to 30m. All Cartier watches come with a two-year international guarantee, which can be extended to eight years through Cartier Care, unlocking exclusive benefits and services.
