Housed in an 18k rose gold (750/1000) case measuring 40mm in diameter and 12.4mm thick, the Ballon Bleu de Cartier WGBB0039 carries the brand's hallmark fluted crown set with a sapphire cabochon — the detail that gives the collection its distinctive silhouette. A sapphire crystal protects the dial, and the watch offers water resistance to 3 bar, approximately 30 meters or 100 feet.
The silvered guilloché dial is paired with blued-steel sword-shaped hands, while a calendar aperture sits neatly at 3 o'clock. Power comes from Cartier's manufacture mechanical movement with automatic winding, caliber 1847 MC. The watch is fitted with an 18k rose gold (750/1000) interchangeable bracelet.
This example is presented as a full set, complete with its original box and papers.
