Floating like a balloon and as blue as the sapphire safely nestled in its side, the Ballon Bleu watch by Cartier adds a dash of elegance to male and female wrists alike. Roman numerals are guided on their path by a sapphire cabochon winding mechanism protected by an arc of precious metal. With the convex curves of the case, guilloche dial, sword-shaped hands, and polished or satin-finish links of the bracelet, the Ballon Bleu watch by Cartier floats through the world of Cartier watchmaking.
