Audemars Piguet Royal Oak 26579CE White Ceramic Modification ✈️
- Case & Bracelet: CNC original‑data developed German‑imported white ceramic case and bracelet – color and texture perfectly match the genuine.
- Movement: Upgraded with a genuine 2120 caliber, modified to achieve full perpetual calendar functionality, including week indication.
- Dial, Hands & Moon Phase: Top‑tier aftermarket dial, hands, and moon phase developed from original data.
This is a high‑end custom build of the AP Royal Oak 26579CE, the highly sought‑after white ceramic perpetual calendar. The modifications are both ambitious and technically sophisticated:
- Case: The use of German‑imported white ceramic with original‑data CNC machining ensures the correct milky‑white hue, fine brushing, and polished bevels – critical details that distinguish this reference from standard steel or gold models.
- Movement: The heart of this build is a genuine AP 2120 caliber, one of the thinnest automatic movements ever made. It has been extensively modified to incorporate a full perpetual calendar module, featuring date, day, month, moon phase, leap year, and even week indication (displayed via a central hand and the outer chapter ring). This is no small feat – the original 2120 did not have a week display. Achieving this function in a custom build is a testament to the watchmaker’s skill and demonstrates the potential of the 2120 platform beyond its original design.
- Dial & Hands: The top‑tier aftermarket dial, hands, and moon phase disc are developed from original data, replicating the iconic blue “Grande Tapisserie” pattern, silver sub‑dials, and the precise layout of the perpetual calendar.
Why this matters:
The genuine 26579CE, introduced in 2019, was the first Royal Oak to feature a ceramic case and bracelet combined with a perpetual calendar, and it quickly became a modern classic. However, its retail price (around $80,000+) and limited availability make it inaccessible to many collectors. This custom build offers a compelling alternative: a solid white ceramic case and bracelet, a genuine AP 2120 movement upgraded to full perpetual calendar functionality, and meticulously crafted dial components. For collectors who value both the aesthetic purity of white ceramic and the mechanical complexity of a perpetual calendar, this build delivers a near‑factory experience at a fraction of the cost. The addition of the week display – a signature feature of the 5134 caliber – sets this build apart and highlights the careful attention to detail.
A white ceramic AP Royal Oak perpetual calendar with a real 2120 movement inside, upgraded to do everything the original 5134 does – date, day, month, moon, leap year, and even the week number on the outer ring. The case is spot‑on German ceramic, and the dial is top‑tier aftermarket. This is a serious build for collectors who want the look and function of the 26579CE without the sticker shock.
