Ballon Bleu de Cartier
The Ballon Bleu de Cartier collection has quickly become an icon. Taking its name from the spherical ‘balloon’ shape of the case, it gives volume to the circle and is undeniably elegant, with a design that is in perfect harmony with those who wear it and the world that surrounds it. With roman numerals, classic guilloche and distinctive sword-shaped hands, as well as the distinctive blue sapphire cabochon enclosed by an arc of metal, it has become a celebrated icon in the world of watches.
