Description
At the heart of the Audemars Piguet Royal Oak Perpetual Calendar 26674ST.OO.1320ST.01 beats a movement engineered to track the complexities of our calendar system through 2100, requiring no adjustment for leap years across multiple centuries. The 2025 production features a striking blue “Grande Tapisserie” dial housed within a 29.6mm stainless steel case, showcasing Audemars Piguet’s mastery of both horological mechanics and the iconic waffle-pattern texture that defines Royal Oak aesthetics. This reference represents the perfect convergence of perpetual calendar complications and the architectural brilliance of Gérald Genta’s legendary 1972 design, delivered in an unworn example complete with factory documentation.
Key Features & Specifications
Grande Tapisserie Dial Artistry — The blue “Grande Tapisserie” finish employs a larger waffle pattern than the traditional Petite Tapisserie, creating deeper shadows and more pronounced geometric depth that emphasizes the dial’s architectural character while housing seven distinct calendar indications.
Perpetual Calendar Complication — Tracks day, date, month, leap year cycle, astronomical moon phases, and week indication through 2100 without manual correction, representing one of haute horlogerie’s most sophisticated achievements in mechanical calendar calculation.
Integrated Steel Construction — The 29.6mm stainless steel case flows seamlessly into the matching integrated bracelet, maintaining the Royal Oak’s signature alternating brushed and polished surfaces across case, bezel, and links.
55-Hour Power Reserve — The ultra-thin 4.1mm movement maintains consistent timekeeping and calendar accuracy across more than two full days, essential for the reliable operation of complex perpetual calendar mechanisms.
2025 Production Provenance — Unworn condition with complete box and papers documentation, representing the latest evolution of Audemars Piguet’s perpetual calendar expertise in the modern Royal Oak architecture.
50-Meter Water Resistance — Engineered to withstand daily wear while protecting the intricate perpetual calendar movement, secured by the signature AP folding clasp system.
