This reference is valued for its combination of a stainless steel case and bracelet with a skeletonized tourbillon movement, a pairing typically reserved for precious metals or titanium. It houses the manual-wind Calibre 2924, which measures 4.46mm thick, allowing for a total case height of 8.95mm. The openworked architecture features slate grey bridges and a visible mainspring barrel at the one o'clock position. On the secondary market, this reference typically trades in the mid-to-high six-figure range, often between $450,000 and $650,000 depending on condition and provenance. A notable auction result occurred in 2021 when a specimen sold for approximately $770,000, reflecting the scarcity of steel-cased complications within the Royal Oak lineage compared to their gold counterparts.", "score": 202}]}
