Replica Ballon Bleu 33661
Replica listings for the 33661 copy the 42mm case shape. The caseback engraving, crown spinel, and dial printing are the common weak points. Many replicas use a clone 2892 or a 2824 clone. The rotor engraving and movement finish do not match Calibre 049. Power reserve is often 38 to 40 hours. The bracelet fit and clasp engraving vary by factory. Water resistance is claimed at 30m but is not tested. A replica has no Cartier warranty and no service network. A local watchmaker may refuse to service it. The date font and the spacing of the Cartier logo are easy tells. The secret signature in the VII numeral is often missing or placed wrong.
