Exemplifying Cartier's timeless elegance, this 2010s Ballon Bleu model, W69004Z2, features an 18K rose gold 36.6mm case and bracelet. Its silver guilloche dial showcases painted roman numerals and blue sword-shaped hands, protected by a scratch-resistant sapphire crystal. A signature blue sapphire cabochon graces the fluted crown. Designed to fit up to a 7-inch wrist, this automatic self-winding watch, while previously worn, stands as a testament to Cartier's unmatched craftsmanship.
