Editors’ Notes

The 'Ballon Bleu de Cartier' watch is destined to be loved and passed down to the next generation - it's elegant, sophisticated and timeless. Made in Switzerland from polished 18-karat pink gold, this 36mm automatic model is encrusted with 123 brilliant-cut diamonds and defined by a floating sapphire-tipped crown. The dial is punctuated with classic Roman numerals, while the signature blued steel hands are clear and easy to read. The lilac alligator strap makes it the perfect option for both evening and daytime events.

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.
