Audemars Piguet Royal Oak 37

This is the Audemars Piguet Royal Oak ref. 15551ST. This is a 37mm Royal Oak that has added glamour without losing the plot: the diamonds trace the iconic octagonal bezel rather than overwhelm it, and the deep blue tapisserie dial underneath is the one everyone actually wants. This is the current-generation Royal Oak with the 5900 movement. 37mm is a sweet spot for APs — big enough to wear with presence, sized to work on any wrist. This particular version is in excellent preowned condition with some minor surface marks on the bracelet and clasp - not very noticeable. No major wear to note. Originally purchased December 2025 - Includes the original box.
