Housed in a 42mm steel case measuring 13mm thick, the Ballon Bleu WSBB0025 features Cartier's hallmark fluted crown set with a cabochon-shaped synthetic spinel. The blue dial is dressed with Roman numerals and sword-shaped hands, protected by a sapphire crystal, and the watch carries a water resistance rating of 3 bar (approximately 30 meters).
Power comes from the Manufacture mechanical movement with automatic winding, caliber 1847 MC — a movement developed in-house at Cartier's workshops. The combination of a steel case and a matching steel double adjustable folding buckle gives the watch a cohesive, considered finish.
The watch is presented on a blue alligator-skin strap, lending a tonal elegance that complements the dial. Reference WSBB0025 carries the Cartier model designation Ballon Bleu de Cartier.
