Reference 15514BC.YY.1284BC.04 takes the Royal Oak silhouette into gem-set territory, housing a 41mm case and matching bracelet in 18K white gold. The bezel alternates graded blue sapphires with Swiss-blue topazes to produce a shifting gradient of colour, while the dial itself is composed of graded blue sapphires that carry that same Tapisserie motif across a surface defined entirely by precious stones.
Inside, the self-winding Calibre 4309 keeps time through hours, minutes, and central seconds, supported by a 70-hour power reserve. An AP folding clasp secures the 18K white gold bracelet, and the watch carries a water resistance rating of 20 metres.
This example is presented complete with its original box and papers. The reference 15514BC.YY.1284BC.04 sits at the intersection of haute joaillerie and mechanical watchmaking, offered here with full documentation for the discerning collector.
