Pre-owned Ballon Bleu de Cartier ref. WSBB0049 (2021) is one of Cartier’s most distinctive modern collections. The Ballon Bleu came to market in 2007 and was a departure from the brand’s signature rectangular designs, featuring instead a graceful round case and an integrated winding crown set with a blue cabochon and protected by an elegant crescent-shaped crown guard that flows seamlessly into the case. This clever design shares space with the date on this model, adding to the collection’s famous aesthetic. This 42mm stainless steel example features a silver dial with Cartier’s signature Roman numeral hour markers, blued steel sword-shaped hands, and a finely detailed guilloché center that adds depth and texture to the display. Powering the watch is Cartier’s caliber 1847 MC automatic movement, with the “MC” designation signifying that it is a Manufacture Cartier movement developed and produced in-house. The result is a refined everyday luxury watch that perfectly balances contemporary styling with the timeless design language for which Cartier is known.
