Audemars Piguet Royal Oak Perpetual Calendar White Ceramic 26579CB.OO.1225CB.01 — Haute Horlogerie in Daring White

Redefining technical brilliance with modern aesthetics, the Audemars Piguet Royal Oak Perpetual Calendar Ref. 26579CB.OO.1225CB.01 is a bold masterpiece crafted entirely in white ceramic, housing one of the most revered complications in horology, the perpetual calendar. This reference is an emblem of avant-garde design meeting traditional craftsmanship, dressed in an ice-white armor with a mesmerizing “Grande Tapisserie” blue dial.

Crafted in hand-finished white ceramic, this Royal Oak Perpetual Calendar features day, date, month, astronomical moon, and week of the year. The leap year indication — pioneered by Audemars Piguet in 1955 — is also featured on the “Grande Tapisserie” decorated dial.

The Royal Oak Perpetual Calendar in white ceramic stands as a technical and design milestone. Not only is it incredibly challenging to craft such a complex case and bracelet in ceramic—requiring up to five times more machining than steel, but it’s also ultra-wearable due to its lightweight, scratch-resistant properties. Combined with the highly intricate Calibre 5134, this reference balances sport-luxury with horological prestige like few others. 

Functions: Perpetual calendar (day, date, month, leap year), week indication, moon phase

The layout of the perpetual calendar is impeccably symmetrical:

Week of the year tracked around the outer chapter ring with a central hand

The blue dial is decorated with AP’s signature “Grande Tapisserie” guilloché pattern, offering dramatic contrast against the white ceramic case and white print on subdials. Applied white gold hour markers and luminescent Royal Oak hands add legibility and elegance.
