Royal Oak Selfwinding 15500ST (Blue Dial)
The 41mm Royal Oak Selfwinding 15500ST, successor to the 15400ST, defines the integrated-bracelet steel sports watch with its Gerald Genta octagonal bezel and "Grande Tapisserie" blue dial. The price shown is the original boutique list price rather than a secondary-market quote: Royal Oak steel demand has consistently outstripped supply, pushing this reference well above retail. Because the brushed-and-polished case and bracelet show wear readily, condition is decisive, and a full set with box and certificate of the in-house Calibre 4302 movement earns the strongest valuation. Authentication is critical given the prevalence of high-quality fakes.
A good time to buy — it's at its lowest price on record, right around its 90-day average.
