This Ballon Bleu de Cartier reference WSBB0028 presents the collection's signature round steel case at 36mm with a 12.1mm profile. The fluted crown is set with a cabochon synthetic spinel, a hallmark detail that defines the Ballon Bleu silhouette, while a scratch-resistant sapphire crystal protects the dial beneath.
The silver guilloché opaline dial is read through Roman numeral hour markers and blued-steel sword-shaped hands, with the automatic mechanical movement delivering hours, minutes, and seconds. The case offers water resistance to 3 bar (approximately 30 meters).
A black alligator leather strap with a steel deployant buckle completes the watch. This example is Swiss Made, dated 2024, and accompanied by its original box and papers.
