Pre-owned Cartier Ballon Bleu W4BB0016 (2013 – 2023) takes one of Cartier’s most recognizable designs and adds a layer of mechanical complexity with a chronograph. The Ballon Bleu, introduced in 2007, is known for its rounded case, soft curves, and signature crown set into a “bubble” guard that flows seamlessly into the caseband. This model keeps that DNA but integrates chronograph pushers on either side of the crown, giving it a slightly sportier profile without losing its refined feel. The dark dial features a guilloché center framed by bold Roman numerals, while the layout is reworked to accommodate two sub-dials at 3 and 6 o’clock, with the date moved over to 9. At 33mm, the steel case is compact and elegant, paired with a leather strap for a more classic look. Shop Cartier Watches Shop Cartier Ballon Bleu Watches
