Cartier Ballon Bleu WE902077 Silver Diamond 18k Rose Gold Stainless Steel Women's Wristwatch 33 mm

Launched in 2007, the Ballon Bleu collection revolutionised Cartier’s design language and has long been admired for its modern romance. Its name is drawn from the French words “ballon,” evoking the soft roundness of a floating balloon, and “bleu,” a tribute to the winding crown adorned with a luminous blue sapphire cabochon. Crafted from a blend of 18k rose gold and stainless steel, its most striking feature is the radiant diamond-set bezel, which encircles the dial like a halo of light. The "secret" of the design lies in the integrated crown guard, which creates a unique indentation in the dial at 3 o'clock, making it feel intimate.
