The Cartier Ballon Bleu Tourbillon W1580002 is an extraordinary timepiece that elevates the Ballon Bleu collection to new horological heights. This model features a 46mm 18k white gold case with a substantial yet refined presence. At its heart is the Cartier Caliber 9452 MC, a hand-wound mechanical movement certified with the Geneva Seal, showcasing an exquisite flying tourbillon complication visible at 6 o’clock. The silvered guilloché dial is adorned with bold Roman numerals and blued steel sword-shaped hands, maintaining the classic Cartier aesthetic. The signature fluted crown, set with a blue sapphire cabochon, enhances the iconic design. The watch is paired with a luxurious black alligator leather strap, secured by an 18k white gold deployant buckle. A sapphire crystal protects the dial, while the case provides a water resistance of 30 meters. This Ballon Bleu model is a symbol of technical mastery and prestige, appealing to collectors who appreciate fine complications.
