Measuring 42mm, the rhodiumized 18k white gold case of this Ballon Bleu de Cartier is set with 210 brilliant-cut diamonds totaling 3.38 carats, and features Cartier's signature fluted crown crowned by a sapphire cabochon. The caliber 430 MC manufacture manual winding mechanical movement powers the watch, delivering a refined mechanical heartbeat within this jeweled exterior.
The 18k white gold NAC-treated dial continues the diamond theme with 123 vibrant brilliant-cut diamonds totaling 3.46 carats, while blued-steel sword-shaped hands track the hours with elegant precision. A black semi-matte alligator skin strap secures the watch via a rhodiumized 18k white gold double adjustable folding buckle, itself set with 43 brilliant-cut diamonds totaling 0.42 carats — extending the diamond work from case to clasp.
Water resistance is rated to 3 bar (approximately 30 meters / 100 feet). As a limited edition of 100 individually numbered examples, carat weight and stone count may vary slightly from piece to piece, consistent with Cartier's approach to handcrafted jeweled timepieces.
