More than fifty years after Gérald Genta sketched an octagon overnight, the Royal Oak remains the watch that justified every steel sports watch that followed it. The 15510ST is the reference as it stands today: 41 mm, the in-house calibre 4302 behind sapphire, and the blue “Grande Tapisserie” dial that reads as the model's signature.

What separates a fine Royal Oak from an ordinary one is finishing — the knife-edge bevels, the interplay of brushed and polished surfaces across case and bracelet. An unworn example preserves all of it, exactly as Le Brassus intended.

This watch is offered unworn and complete. For the collector beginning with Audemars Piguet, there is no better first chapter.

Unworn, with protective films in place and bracelet unsized. Complete with original box, certificate and booklets.
