This replica Royal-Oak 26579CE is the Royal Oak Perpetual Calendar in ceramic, sharing the same case construction approach as the 26579CB but in a different ceramic color execution. The CE code marks the black ceramic version; the CB is white ceramic with a blue dial and the CS is blue ceramic. At 41mm the case houses the full perpetual calendar complication: day, date, month, astronomical moon phase, and leap year tracking, all operating autonomously without manual correction for decades. Ceramic as a case material for a grand complication represents a modern evolution of what the Royal Oak can be.

Ceramic achieves scratch resistance that surpasses both steel and gold. The material maintains its surface condition over years of daily wear in a way that metal cannot, which matters for a complicated watch intended to be worn for decades.

What Collectors Notice

The 26579CE sits alongside the 26579CB in the ceramic perpetual calendar sub-family, and the distinction between them comes down to surface color and finish. Collectors tracking AP reference numbers read the CE suffix as black ceramic, the first ceramic Royal Oak Perpetual Calendar, introduced in 2017. The perpetual calendar layout follows the same four-subdial arrangement as every Royal Oak perpetual, with moon phase at 6 o’clock and leap year indication integrated into the dial design. The finishing on ceramic bracelet links mirrors the satin and polish pattern of metal links, translated into a non-metallic medium. Compare this against the 15500ST blue dial to see the same case shape in conventional steel. The full Royal Oak range shows how AP distributes complications across every available material.

This vs Other Versions

Choosing between the CE and CB ceramic perpetual calendars comes down to color preference and wardrobe alignment. Both offer the same lightweight scratch-resistance advantage over metal, and both house identical perpetual calendar mechanics. The CE version adds another option for collectors who want a ceramic Royal Oak perpetual calendar in all-black ceramic rather than the white CB or the blue CS. Material choice at this complication level is about personal alignment, not technical superiority, since the calendar module inside does not change. This replica Royal-Oak 26579CE brings that ceramic perpetual calendar experience in a variant that broadens the options beyond all-black.
