Cartier · Family: Ballon Bleu de Cartier
The Cartier Ballon Bleu de Cartier WSBB0049 is the 42mm steel version of the line that in 2007 introduced Cartier's rounded, domed case with a protective arc over the crown — one of the most recognizable designs in the maison's current catalog. It runs the in-house automatic Caliber 1847 MC with a silver guilloché dial. Cazador has no verified price observations (n=0) for this reference as of today.

Cartier was founded in Paris in 1847 and, over a century and a half later, introduced the Ballon Bleu de Cartier line in 2007, with a design that broke from the maison's tradition of rectangular or flat round cases. Its distinctive feature is the metal arc running across the case to protect the cabochon-topped crown, giving the overall silhouette the rounded, ball-like profile that gives the line its name.
This reference, the WSBB0049, is the 42mm steel version with a silver guilloché dial, an in-house automatic movement (Caliber 1847 MC), and blued sword-shaped steel hands — a design vocabulary shared with other Cartier lines such as the Tank.
Water resistance sits at 3 bar (roughly 30 meters), a modest figure consistent with its role as a dress watch for daily wear rather than a sporting tool. The sapphire crystal and interchangeable steel bracelet round out a proposition that, since its launch, has become one of the most recognizable lines in Cartier's current catalog alongside the Tank and the Santos.
