Look closely at the Ballon Bleu watch and you will see that it is more than just a round watch. Dial-side and case back, the watch is rounded, giving it the likeness of a pebble when seen in profile. It is this characteristic that marks and unites the collection, above all others. This design cue is unique to the Ballon Bleu, making it distinct from Cartier’s other noble watches.

Contrary to what one might assume, the pebble-shape does not make this watch difficult to wear. Instead, it gives a Ballon Bleu de Cartier watch the appearance of floating magically just above the wrist. In effect, the watch appears to orbit the wrist, to return to the cosmological metaphor.

The mixed watches Cartier “Ballon Blue” is the new best-sellers of the house Cartier. Round index Roman guilloche dial and sword hands – signs of identity of the house – at first glance, this watch seems ultra classic. It deserves, however, that it focuses on one detail in particular. Its funny winder, which gave its name to the line, is decorated with a cabochon sapphire embracing in a circle of gold. An unlikely focused satellite in orbit.
