Overview
The Cartier Ballon Bleu 40 reference WSBB0039 presents the collection's hallmark rounded case in 40 mm stainless steel, paired with a silvered guilloché dial dressed with Roman numerals. Calibre 1847 MC, an in-house movement developed by Cartier, powers the watch with a self-winding mechanism suited to everyday elegance. The result is a dress watch that balances architectural boldness with the restrained refinement expected of the Ballon Bleu line.
History
The Ballon Bleu de Cartier was introduced in the mid-2000s and quickly became one of the maison's most recognisable contemporary references, distinguished by its domed sapphire crystal, concealed crown set within a protective cabochon, and fluid, spherical case profile. The 40 mm stainless steel variant occupies the mid-size position in the line, appealing to collectors who favour a versatile, wearable expression of the design. Reference WSBB0039, with its guilloché silvered dial, entered production in 2019 and continues to represent the Ballon Bleu in its most accessible steel configuration.
