The Ballon Bleu de Cartier WE902036 is constructed from 18k rose gold, a material chosen for its resistance to tarnishing and its warm hue. The case measures 33mm in diameter and features the model’s signature rounded, convex case profile and fluted crown guard set with a synthetic blue spinel cabochon. The bezel is set with 48 full-cut diamonds, channel-set into the gold, with a total approximate weight of 0.25 carats. The dial is a silvered guilloché finish with black Roman numerals, including the VII replaced by the Cartier signature, and features blued steel sword-shaped hands. The watch is fitted with a genuine brown alligator leather strap and an 18k rose gold ardillon buckle. This combination of materials and traditional finishing techniques results in a classic and heritage-rich aesthetic that has defined the Ballon Bleu collection for years.
This timepiece is powered by the Cartier Calibre 076, a quartz movement. This movement provides accurate timekeeping with minimal maintenance required beyond periodic battery changes. The watch is a time-only model, displaying hours and minutes, with no additional complications. The use of a quartz movement is a practical choice for a piece of this nature, prioritizing reliability and ease of use in a formal watch. The dial’s design is clear and legible, adhering to a traditional layout that has been a staple of the brand’s identity for over a century, making it an enduring and straightforward time-telling instrument.
The watch is presented in mint condition, showing no visible signs of wear on the case, bezel, or crystal. The brown alligator strap is in unworn condition. The watch is accompanied by its presentation box and a valid Cartier warranty card, which serves as the official documentation for authentication and service purposes. Within the current market, the Ballon Bleu remains one of Cartier’s most recognizable and consistently demanded models. This specific configuration, with its diamond bezel and rose gold case, holds its value well due to its timeless design and the enduring appeal of precious materials. It represents a solid entry into luxury watch collecting, offering a blend of traditional Cartier design codes and a robust market position that ensures its long-term collectibility.
