Watchuwant is now WatchBox! Subscribe for the best luxury watch content. The Ballon Bleu de Cartier is the breadwinner for the juggernaut Richemont Group's number-one moneymaker. And luxury watches like this Cartier Ballon Bleu "Chocolate Guilloche" Automatic are the reason. At 42mm in polished stainless steel and 18-karat rose gold, this feels like the watch Louis Cartier would have designed had he lived in the post-Y2K world. Consider the magnitude of the Ballon Bleu's success; no branch of the Richemont Swiss luxury conglomerate - the second largest in the world - thrills more customers than Cartier, and no Cartier watch is more coveted than the Ballon Bleu. Since its 2006 launch, the Cartier Ballon Bleu has defined "lighting in a bottle" throughout the watch industry. Particularly scintillating (and galling from the perspective of envious Swatch and Rolex execs) has been the Ballon Bleu's performance on the now paramount Hong Kong/Chinese market. More than a successful watch, the Cartier Ballon Bleu has become a full-featured line of diverse sizes, materials, and complications. At 42mm in versatile polished steel and warm rose gold, the Cartier Ballon Bleu Automatic boasts immense presence on the wrist. From a visual standpoint, few dress watches pack a comparable impact without resorting to gimmicks or faddish hooks. The Ballon Bleu pulls off an aesthetic coup simply by balancing the interplay of its many compound curves, the all-of-a-piece flow from case to bezel to sapphire, and the minimal lugs that enable the watch to assume the appearance of an organic silver extension of the wrist itself. Beneath the Ballon Bleu's already-iconic crown guard, an enormous blue sapphire cabochon sits atop the oversized round crown. The gemstone’s rich “bleu” luster is evocative of Cartier’s roots as a jeweler par excellence and confirms the Paris maison’s status as a master of fine materials. Due to the even and broad stance of the Cartier Ballon Bleu case, even the 42mm variant sits lightly upon the skin. The slight curvature of the case back allows the Ballon Bleu to nestle gently on the skin without the bruise-inducing pressure points created by some steel sports watches of comparable size. The Cartier Ballon Bleu in 42mm distributes its weight gently, and the barely-there lugs enable this full-sized model fit comfortably even on wrists as small as 6" in diameter. This Cartier Ballon Bleu features a dial that is unmistakably Cartier but completely unique within the Ballon Bleu lineup. Chocolate guilloche cuts (Cartier's own term!), bold copper Roman numerals, the signature rose gold broadsword hands, and artful integration of date and inboard minute track complete the image of traditional Cartier elegance. With tones of gold, tobacco, and cocoa, this dial will bring a smile to your face even as it makes your mouth water... Already considered a modern classic and a permanent pillar of the house Louis built, the Cartier Ballon Bleu is the world's favorite watch from the number one name in Francophone fashion.
