The replica royal oak 26574OR is a perpetual calendar in full 18K rose gold — one of the more complex functions AP puts into the 41mm case. Four sub-dials track day, date, month and moon phase without needing a manual correction until 2100. The blue dial against warm rose gold creates a contrast that works in person better than it photographs. Cal. 5134 runs at 19,800 vph with a 52-hour reserve, which is conservative but reliable for a movement this thin.
Perpetual Calendar in Practice
The 26574 perpetual calendar uses four recessed sub-dials arranged symmetrically across the face. Day at 9, date at 3, month at 12, moon phase at 6. Each sub-dial sits slightly below the main dial surface with its own miniature hand. The layout keeps things legible despite the density of information — nothing overlaps, nothing crowds.
What separates this from a standard annual calendar is the leap year mechanism. The Cal. 5134 tracks the 28/30/31-day cycle automatically and accounts for February in leap years. You set it once and leave it alone. The only correction needed is a single-day adjustment on March 1, 2100 — a problem for someone else.

Blue on Rose Gold
The .02 dial designation on this replica royal oak 26574OR indicates the blue variant. Against 18K rose gold, blue dials shift tone depending on the light — almost black indoors, distinctly blue under daylight. The pink gold applied markers and hands pick up warmth from the case and bracelet, which ties the whole piece together visually. The Grande Tapisserie pattern on the main dial surface catches light at every angle.
The steel version of this same reference — the 26574ST — offers the same movement and layout at a lower price point and roughly half the weight on the wrist. Rose gold adds density and presence that steel cannot replicate. For details on delivery timelines, see our shipping page.
