Editors’ Notes

Cartier's 'Ballon Bleu' reference is named for the 36mm round case that's modeled on the shape of a balloon, along with the blue cabochon nestled at the side, which gives the illusion it's floating. Impeccably crafted from 18-karat rose gold, this timepiece flaunts a sunray silvered dial encrusted with 21 brilliant-cut diamonds that make it all the more striking. It features blued steel sword-shaped hands that beautifully complement the alligator strap.

All Cartier watches still within the initial 2-year warranty period under the original International Limited Warranty will be eligible to benefit from a 6-year extension, for a total of 8 years warranty.
