Cartier Ballon Bleu 42mm Stainless Steel WSBB0025 BLUE ROMAN BLUE CROCODILE

The Cartier Ballon Bleu de Cartier in this specific 42mm stainless steel configuration with a blue Roman numeral dial and matching blue crocodile strap represents a particularly sophisticated execution of the collection’s signature design language. The defining feature is the rounded case with its convex synthetic sapphire crystal, which creates a distinctive optical distortion at the edges. The fluted crown guard, housing a blue synthetic sapphire cabochon, is seamlessly integrated into the caseband, preserving the watch’s elegant and fluid silhouette. The silvered opaline dial features classic Roman numerals, with the III, VI, IX, and XII rendered in a larger, more pronounced font. The sword-shaped blued steel hands provide excellent legibility against the dial’s clean backdrop. The strap is genuine blue crocodile leather, fitted with a double-adjustable folding buckle for a secure and comfortable fit.

Powering this timepiece is the Cartier Calibre 1847 MC, an automatic movement that operates at a frequency of 28,800 vibrations per hour and offers a 42-hour power reserve. This movement is engineered for reliability and features a paramagnetic alloy balance spring, enhancing its resistance to magnetic fields. The watch functions as a time-only piece, with central hours, minutes, and a subsidiary seconds dial at the 6 o’clock position. This focus on essential timekeeping underscores the model’s classic and uncluttered design philosophy. The movement’s construction prioritizes longevity and serviceability, consistent with Cartier’s approach to its core collection watches.

This particular example is in mint condition, showing no visible signs of wear on the case, lugs, crystal, or strap. The case retains its original brushed and polished finishes, with all edges remaining sharp. It is accompanied by its official papers, which confirm its authenticity and provide documentation for service history. The Ballon Bleu 42mm remains a cornerstone of Cartier’s watchmaking catalog, and this specific reference with the blue dial and strap combination is a consistently sought-after variant. Its position in the pre-owned market is strong, as it represents a modern classic from a premier Maison, appealing to collectors who value its impeccable design and the inherent value retention of a well-maintained Cartier.
