Audemars Piguet Royal Oak 26579CE.OO.1225CE.01 Black Ceramic Moon Phase 41mm

The 26579CE.OO.1225CE.01 puts its buying reason on the dial. The calendar indications and moon-phase display create several points of focus, while the black Grande Tapisserie surface gives those elements a coherent background. This is not a quiet time-and-date Royal Oak; it is for a collector who enjoys returning to the dial and finding another indication to read.

The 41mm case gives the display enough room to breathe. Black ceramic keeps the octagon, bezel screws and integrated bracelet in the same visual family, so the watch has presence without relying on a bright metal contrast. Under a cuff it remains controlled; in a casual rotation the moon-phase aperture supplies the detail that makes the watch immediately recognisable.

The APSF Edition uses the listed Clone AP Caliber 5134 configuration. The factory choice matters here because the calendar-led layout is the reason to buy this reference, not an interchangeable movement label. The integrated ceramic bracelet continues the case line into a double-deployant clasp, keeping the dark geometry intact around the wrist.

Compared with the green-dial Royal Oak calendar, this version makes material unity the first impression. The green calendar alternative separates dial and case for a more traditional contrast; the black ceramic 26579CE is the better fit when the display and the case should feel like one composition.

Before dispatch, our QC team reviews octagonal bezel, ceramic screw seating, calendar alignment, moon-phase aperture, bracelet articulation and deployant clasp.
