One more new one from Cartier, the Ballon Bleu Extra-Flat is has a 40mm rose-gold case with a slim 6.9 mm thickness. A white gold model is also offered, though I really like the aesthetic Cartier has achieved with the rose gold/gray combination. Similar to the Ballon Bleu flying tourbillon (though without the enamlling), the dial has attractive flinqué style decoration on the dial, applied Roman numerals, slender sword-shaped hands, and the blue sapphire cabochon crown protected by a curved arch that gave the original Ballon Bleu watch its name. The manual wind movement is the 430MC (base Piaget). Price on this piece is $19,500.
