With a convex protective case giving the illusion that the watch is floating above the wearer’s wrist, the Ballon Bleu de Cartier Ladies’ Watch is immediately recognisable. This 33mm diameter model is a stunning example from the Ballon Bleu collection. With a mechanical self-winding movement, the lustrous sapphire crystal spinel is set atop the steel fluted crown and protected by the flowing arc of the casement. The impressive 0. 63 Total Carat Weight of 50 brilliant-cut diamonds are set in the steel bezel that surrounds the radiant sunray effect silvered flinqué dial. This high-performance watch is water resistant to 30 metres, while the dial features bold Roman numerals for enhanced legibility. First released in 2006, the Ballon Bleu de Cartier family is characterised by its spherical balloon shape case and distinctive sapphire cabochon crown, guarded by an arc of precious metal.
