The Cartier Ballon Bleu de Cartier WSBB0015 is a strikingly modern interpretation of Cartier’s iconic Ballon Bleu collection. Featuring a 40mm stainless steel case with a black ADLC (Amorphous Diamond-Like Carbon) coating, this timepiece combines timeless elegance with contemporary design. The deep black dial is accented by bold Roman numerals, sword-shaped hands, and Cartier’s signature rail-track minute markers. The fluted crown, adorned with a synthetic blue spinel cabochon, adds a refined touch. Powered by an automatic movement, the WSBB0015 is perfect for those who seek a watch that blends tradition with modernity.
