Cartier Ballon Bleu WJBB0038

Reference WJBB0038 is a Ballon Bleu in an 18k rose gold case with a diamond-set bezel, in the model's rounded, cushion-shaped 42mm case that departs deliberately from the angular Santos and Tank silhouettes that otherwise define Cartier's watchmaking. The blue cabochon-topped crown, protected by a curved guard integrated into the case rather than sitting exposed, is the detail that gives the entire line its name and remains unchanged across every Ballon Bleu reference Cartier has produced.

The diamonds set into the bezel are cut and matched specifically for this reference, following the case's rounded profile rather than the straight-edged bezels seen on Cartier's more architectural watches, and the rose gold case reads considerably warmer and more jewellery-adjacent than the brand's steel sports references. At 42mm, the case sits large enough to read clearly as a statement piece without losing the rounded, cushion-like proportions that distinguish the Ballon Bleu from every other Cartier line.

Diamond-set gold Ballon Bleu references occupy their own distinct corner of Cartier's catalogue, sourced by buyers who want the brand's watchmaking presented as fine jewellery first and a timepiece second. Bezel stone security is checked especially closely given the value concentrated in the setting. Crown guard function and rose gold surface condition are checked closely, since the curved guard is a moving part unique to this line and worth testing directly. Every piece Clutch sources is independently authenticated through Legit Grails, with condition documented and shared directly before any commitment. Enquire to discuss availability and pricing.
