First introduced in 2007, its rounded case, integrated crown guard and signature Roman numeral dial have since become hallmarks of the maison’s contemporary design language. The name “Ballon Bleu” refers to the blue sapphire cabochon nestled within its protective arc — a detail that gives the watch its poetic name and instantly recognisable silhouette. This reference 3009 features a 28 mm stainless steel pebble-shaped case, whose softly domed sapphire crystal merges effortlessly with the polished convex bezel and rounded caseback. The integrated crown guard gently sweeps around the iconic sapphire cabochon crown, creating a harmonious, sculptural form that feels fluid from every angle. The white dial bears Cartier’s painted Roman numerals in black and elegant blued steel sword hands, perfectly balancing classical refinement with modern curves. The III numeral subtly curves inward — a design flourish to accommodate the crown guard. Completing the piece is a stainless steel bracelet with alternating brushed and polished links, secured by a concealed butterfly clasp that maintains the bracelet’s sleek, uninterrupted profile. Inside ticks a precise Swiss quartz movement, ensuring everyday reliability within Cartier’s timeless aesthetic. This Ballon Bleu comes with its original Cartier box, offering a classy presentation of this beautiful watch.
