Cartier's 'Ballon Bleu' 40mm watch has an elegant circular bezel, which is reminiscent of a hot air balloon, hence the name. Powered by a precise automatic movement, it has a date window at 3 o'clock and blued sunray-brushed dial to match the spinel crystal cabochon. Both the case and bracelet are crafted from polished stainless steel, so it makes a most elegant choice of timepiece. We offer a two-year warranty for all working parts and manufacturing faults for luxury watches.
