Cartier 18K White Gold Ballon Bleu

When Cartier introduced the Ballon Bleu in 2007, it reimagined the traditional round wristwatch. Rather than relying on conventional case geometry, Cartier created a softly curved silhouette, with its signature blue cabochon crown nestled inside a protective arch.

Reference WE900951 elevates this contemporary design through an 18K white gold case and a double row of brilliant-cut diamonds surrounding its silvered dial.

It is a meeting of Cartier's two historic disciplines: fine jewelry and watchmaking. The result is a timepiece that combines the presence of a substantial 42 mm case with the elegance of the Parisian jewelry house.
