An authentic watch from the luxury watchmaker Cartier, part of one of its most recognizable and elegant collections—the Ballon Bleu. The W6900356 model, crafted entirely from 18-karat yellow gold, embodies the quintessence of Cartier’s classic style—harmonious proportions, a soft case line, and a distinctive crown with a cabochon create a unique, timeless design.

The Ballon Bleu collection, launched in 2007, is distinguished by its rounded case shape and integrated crown, which subtly “blends” into the case’s silhouette—one of the most distinctive elements of Cartier’s design

Its reference number is W6900356. Water resistance is rated to 30 meters. The set includes the original Cartier box (Cartier travel case) and a full set of documents. First sale in 2015.

Cartier is a legendary French manufactory, defining the concept of a jewelry watch for more than a century. The Ballon Bleu line is considered a symbol of sophistication, class and universal elegance.
