Floating like a balloon and as blue as the cabochon 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 deep blue winding mechanism. The convex curves of the case, guilloche dial, sword-shaped hands, and polished or satin-finish links of the bracelet ensure that the Ballon Bleu watch by Cartier floats within the world of Cartier watchmaking.
