The Ballon Bleu de Cartier captures the maison’s mastery of harmony, proportion, and elegance. Instantly recognizable by its rounded silhouette and integrated sapphire cabochon crown, the design seems to float weightlessly against the wrist — a study in balance and refinement. Crafted in 18K rose gold, this 33 mm case radiates warmth and sophistication, complemented by Cartier’s signature silvered guilloché opaline dial with blued-steel sword-shaped hands.

At its heart beats the Cartier Calibre 1847 MC, a self-winding mechanical movement that powers hours, minutes, small seconds, and a date aperture at 3 o’clock. The fluted crown—nestled into the case’s iconic curve—features a cabochon sapphire, symbolizing Cartier’s dedication to beauty in every detail. The watch is fitted with a brown alligator leather strap and an interchangeable 18K rose gold deployant buckle, combining comfort with timeless luxury.
