Cartier Ballon Bleu De Cartier Automatic 40mm Stainless Steel Ref. WSBB0039

The Cartier Ballon Bleu de Cartier Ref. WSBB0039 combines French elegance with Swiss precision and is one of the most distinctive designs in haute horlogerie. The gently curved stainless steel case, with its signature crown protected by an arch and the blue cabochon, gives the watch its flowing, "floating" silhouette—a look that is instantly recognizable as Cartier. With a 40mm diameter, the Ballon Bleu makes a statement while remaining understated and easy to pair with any style.

The silver-tone guilloché dial features Roman numerals, fine railway minute track, and elegant sword-shaped hands—classic Cartier codes that come together particularly harmoniously here. Viewed through the domed sapphire crystal, the design appears three-dimensional and vibrant; the date window at 3 o'clock blends discreetly into the overall design. The polished stainless steel bracelet completes the design language, providing a confident, premium feel on the wrist.

Inside beats the in-house 1847 MC automatic movement—built for reliable precision in everyday wear. The Ballon Bleu is also well-suited for daily life thanks to its scratch-resistant sapphire crystal and water resistance up to 30 m. With a case height of just approx. 12.4 mm, it sits comfortably flat on the wrist and transitions effortlessly from a business meeting to dinner. A watch that combines luxury, comfort, and iconic status in a timeless package.
