Ballon Bleu 42

The Cartier Ballon Bleu 42 reference WSBB0027 presents the collection's hallmark rounded case in 42 mm stainless steel, paired with a silvered guilloché dial dressed with Roman numerals. Powered by the in-house Calibre 1847 MC, it occupies the larger end of the Ballon Bleu size range while retaining the line's characteristic elegance. As a dress watch, it bridges formal refinement with everyday wearability.

The Ballon Bleu de Cartier was introduced in the mid-2000s and quickly became one of the maison's most recognisable contemporary references, distinguished by its domed sapphire crystal, concealed crown set within a protective blue cabochon, and softly cushion-shaped case. The WSBB0027 in stainless steel with the 1847 MC movement was produced from 2016 through 2023, representing a sustained chapter in the line's evolution. The Calibre 1847 MC, developed in-house at Cartier, marked the brand's broader commitment to proprietary movements across its core collections. Among collectors, the 42 mm stainless steel configuration is regarded as the most versatile expression of the Ballon Bleu, suited to both formal and smart-casual contexts.
