Introduced in 2007, the Ballon Bleu de Cartier has earned its place as a defining shape in the maison's contemporary portfolio. The rounded case and the crown guard that flows into the case profile are hallmarks of the design, and the W3BB0021 expresses them in a two-material combination of stainless steel and a fixed 18kt rose gold bezel that gives the 33mm round case its warm character.
The silver-tone dial is worked in a guilloché pattern, its hand-engraved surface lending depth and texture as light moves across it. Eleven diamond hour markers replace printed indices, while the distinctive blue hands provide clear contrast against the dial. A scratch-resistant sapphire crystal protects the display, and the automatic movement drives the hour and minute functions within.
The watch is presented on a bracelet fastened by a fold clasp and is offered complete with its original box and papers, dated 2024. Swiss made and finished as a luxury timepiece, the Ballon Bleu W3BB0021 is suited to wearers seeking Cartier's characteristic blend of watchmaking and jewellery craft in a versatile, wearable size.
