Introduced at the 2007 Basel World Fair, this watch represented the maison’s most ambitious design at the time. The rounded sapphire crystal causes the watch to appear as a floating blue balloon when viewed from the crown side.

Presents itself in mint condition with little to no signs of wear. Departing from Cartier’s signature angular and rectangular shapes, the high-polish case features a soft, pillow-like silhouette. The rounded sapphire crystal is elegant from every angle. It is complemented by a playful sunburst blue motif dial.

The functions include hours, minutes, seconds and date. To access the hours and minutes function of the watch, pull out the crown twice and turn either direction. To access the date function of the watch, pull out the crown once and turn either direction. To give power reserve to the watch, simply keep the crown pushed in and turn clockwise.

Comes as a full set, double-boxed with warranty card and white tag.

Powered by a 42-hour power reserve Cartier’s in house Caliber 1847, named after the year the brand was established. Blending heritage, elegance, and innovation, this Ballon Bleu is a reminder to never lose sight of life’s simple joys.
