Audemars Piguet Royal Oak Perpetual Calendar Ceramic 26615CE

In-Depth Review

The Audemars Piguet Royal Oak Perpetual Calendar in black ceramic, reference 26615CE.OO.1239CE.01, represents a bold material evolution for one of watchmaking's most iconic complications. While the Royal Oak Perpetual Calendar has existed in various metals since the 1980s, this 2022 ceramic iteration brings a dramatic aesthetic shift. The 41mm case and integrated bracelet are crafted entirely from black ceramic, a material that is significantly harder and more scratch-resistant than stainless steel while being notably lighter. The blue dial against the matte black ceramic creates a striking contrast that gives the watch a thoroughly contemporary character without abandoning the octagonal bezel and tapisserie pattern that define the Royal Oak.

The automatic Caliber 5134 driving this perpetual calendar handles day, date, month, moonphase, and leap year indications with the precision and reliability that Audemars Piguet has refined over decades of perpetual calendar production. At 20 meters of water resistance, this is not a dive watch, but the ceramic construction makes it remarkably resilient for daily wear. The watch targets the collector who wants a perpetual calendar as a statement piece rather than a safe-deposit-box trophy. Its closest competitors are the Patek Philippe Nautilus Perpetual Calendar 5740 in white gold and the Vacheron Constantin Overseas Perpetual Calendar, though both are precious metal pieces that carry a very different visual weight.

Priced at $105,000 MSRP with a secondary market value of approximately $115,000, the 26615CE demonstrates the kind of modest premium that indicates genuine collector demand without speculative mania. The ceramic case material is technically challenging to manufacture to Royal Oak tolerances, and the full ceramic bracelet with its alternating finishes required significant investment from AP to produce. For the collector seeking a perpetual calendar that can be worn daily without the anxiety of scratching precious metal, and who wants a visual presence that stands apart from the stainless steel and gold crowd, this ceramic Royal Oak Perpetual Calendar is one of the most compelling modern offerings from Le Brassus.
