Cartier describes the Ballon Blue as follows: 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. With the convex curves of the case, guilloché dial, sword-shaped hands, and polished links of the bracelet…the Ballon Bleu watch by Cartier floats through the world of Cartier watch making. This example has a 36mm stainless steel case with the distinct Ballon Blue crown cover. The size allows for wear as a men’s or ladies dress watch. This watch comes with box only.
