Cartier's Ballon Bleu WGBB0017 is built around a 42.1mm 18k pink gold case measuring 13mm thick, crowned by the collection's signature fluted crown set with a blue cabochon-shaped sapphire. A sapphire crystal protects the dial, and the watch carries a water resistance rating of 3 bar (approximately 30 meters / 100 feet).
The silvered guilloché lacquered opaline dial is dressed with Roman numerals and blued-steel sword-shaped hands, with a calendar aperture positioned at 3 o'clock. Inside, a self-winding mechanical movement keeps time reliably within this elegant case.
The watch is paired with an alligator-skin strap secured by an 18k pink gold double adjustable folding buckle, completing a look that balances classic Cartier design language with everyday wearability.
