This incredible Royal Oak "Double Balance Openwork" is absolutely breathtaking. Available to VIP clients through the Boutique only, the demand for the 15407 was so intense that it is now impossible to get from AP. The large 41mm Royal Oak case houses AP's fully skeletonised 3132 calibre movement with two balance wheels mounted opposite one another on the rose bridge for improved precision. Finished in a deep rhodium grey, this unique movement (with its 22ct gold rotor) has a full 45 hour power reserve. In outstanding, crisp condition and totally complete with its original Audemars Piguet box and papers from 2017, this is not one to be missed...
