Measuring 42 mm in diameter and 13 mm thick, the Ballon Bleu de Cartier WGBB0023 is crafted in 18k yellow gold, complete with a matching 18k yellow gold bracelet. The fluted crown is set with a blue cabochon-shaped sapphire — a signature detail that gives the collection its distinctive character.
The silvered guilloché and lacquered opaline dial is appointed with Roman numerals and blued-steel sword-shaped hands, offering a refined contrast against the warm gold case. A sapphire crystal protects the dial, and the watch carries a water resistance rating of 3 bar (approximately 30 meters).
Powering the piece is Cartier's Caliber 1847 MC, a manufacture mechanical movement with automatic winding. As with all pieces in the Ballon Bleu collection, slight variations in stone count or carat weight may occur from one example to the next.
