The reason why the Cartier Ballon Bleu is so popular relies entirely on these four secrets

　　Born in 2007, theCartier Ballon Bleuhas developed over just a few short years into one of the favourite wristwatch styles among the fashion circle, celebrities, and trendsetters. There is a reason why the Ballon Bleu is loved by so many people. Furthermore, the rise in popularity of the Cartier Ballon Bleu is inseparable from these four secrets.

　　I. A streamlined case that is neither entirely round nor otherwise

　　The case design of the Ballon Bleu adopts a smooth, streamlined layout, and the overall wristwatch design is rounded and refined. Among replica watches, it is also a major popular classic. Moreover, both the front and back of the wristwatch are slightly rounded and curved. This design is rare in wristwatches, yet it fits the wrist very well, making it more comfortable for the wearer.

　　II. Extra-large cabochon sapphire crown

　　The crown of the Ballon Bleu is set with an extra-large cabochon sapphire, and the crown guard design is also unique, resembling a blue balloon suspended in mid-air.

　　III. Domed crystal glass

　　The crystal glass of the Ballon Bleu is a convex, domed piece; this design can magnify dial details, making it more convenient to read the time. In addition, when viewed in sunlight from different angles, it can also refract different charming lustres.

　　IV. Distinctive dial design

　　The dial of the Ballon Bleu is highly recognisable: guilloché dial, Roman numerals, railway-track minute scale, and blue sword-shaped blued-steel hands, which are consistent with Cartier's aesthetic tradition. Due to the influence of the crown, the Roman numerals deviate from the normal circular track and curve inwards.
