The Ballon Bleu de Cartier is a graceful timepiece that truly testifies to Cartier's watchmaking mastery. Housed inside a 33mm stainless steel case with a sapphire crystal and solid caseback, it finds its power in a mechanical movement with automatic winding. The case features a fluted crown set with a cabochon synthetic spinel and is offered with a silver guilloché dial that makes it an opulent offering. For contrast, it features blued-steel sword-shaped hands and black Roman numeral hour markers. The case comes paired with a sapphire crystal and offers a water resistance of up to 30 meters. The self winding movement powering the Ballon Bleu de Cartier enables functions like hours, minutes, and seconds.
