Cartier Ballon Bleu 28mm – Steel WE902073 SILVER DIAMOND STEEL

The Ballon Bleu de Cartier is a distinctive and sought-after collection, first introduced in 2007. Its design is immediately recognizable by the convex curves of its case and the protective, fluted crown guard that houses a synthetic spinel cabochon. This particular reference, WE902073, is a 28mm model in stainless steel, a size and material combination that has proven to be highly collectible. The dial is finished in silvered opaline and features a diamond-set chapter ring, with Roman numerals that are a signature Cartier element. The finishing on the case combines polished and brushed surfaces, with particular attention paid to the seamless integration of the case with the bracelet. The bracelet itself is a five-row link design in solid steel, secured by a double-folding deployant clasp.

This watch is powered by Cartier’s caliber 076, a quartz movement. This movement selection prioritizes accuracy and low maintenance, a practical feature for a daily-wear timepiece. The complication is time-only, displaying hours and minutes, which maintains the clean, uncluttered aesthetic of the dial. The sapphire crystal is slightly convex, following the profile of the case, and provides a clear view of the dial’s layout, including the diamond-set markers and the blued steel sword-shaped hands. The water resistance is rated to 30 meters, suitable for everyday splashes.

The watch is in mint condition, showing no visible signs of wear on the case, crystal, or bracelet. It is accompanied by its official papers, which confirm its authenticity and are a critical component for its long-term value. As a limited production model from a major maison, this Ballon Bleu holds a strong position in the pre-owned market. The combination of its iconic design, desirable steel construction, and diamond-set dial makes it an exclusive piece that is both a reliable personal timepiece and a sound acquisition for a collector focused on modern Cartier references. Its value is supported by its documented provenance and its condition, which is as close to new as a previously owned watch can be.
