Audemars Piguet’s Caliber AP 1000 is nothing short of a modern horological masterpiece. Designed to be the pinnacle of technical achievement from one of Switzerland’s oldest family-owned watchmakers, this movement redefines what’s possible in wristwatch engineering. Power, complexity, elegance, and a staggering array of functions all come together in a single caliber that represents AP’s cutting-edge research and development.
What Is the Caliber AP 1000?
The AP 1000 is a self-winding mechanical movement created by Audemars Piguet Manufacture to power their most ambitious timepieces—especially flagship ultra-complication wristwatches such as the Code 11.59 Ultra-Complication Universelle. It stands as a testament to AP’s technical expertise and creative engineering ambition.
At its core, the AP 1000 is designed to be a fully integrated, self-winding ultra-complication movement, combining dozens of traditional high complications into a single, beautifully finished unit.

A Theology of Complications
What truly sets the AP 1000 apart is the breadth and depth of its mechanical functions. Rather than focusing on one or two complications, this movement incorporates an incredible array—making it one of the most mechanically accomplished calibre ever produced for a wristwatch.
Grande and Petite Sonnerie
The movement features a grande sonnerie and petite sonnerie, both enhanced by AP’s Supersonnerie chiming technology for greater acoustic clarity and volume. A separate barrel powers the sonnerie system, ensuring the chime performance doesn’t compromise timekeeping accuracy.
Minute Repeater
One of the most beloved high complications, the minute repeater in the AP 1000 is refined with precision gongs and a mechanism attached to a sapphire crystal membrane, which doubles as an acoustic soundboard to enhance the chime’s resonance.
Tourbillon
The inclusion of a tourbillon escapement demonstrates AP’s mastery over one of watchmaking’s most complex regulating mechanisms. This device counteracts gravitational error to improve precision while showcasing dramatic kinetic architecture.
Chronograph Suite
Rather than a simple stopwatch, the AP 1000 offers a flyback chronograph and split-seconds (rattrapante) functions—allowing timing of multiple events with seamless resetting and split timing capabilities.
Perpetual Calendar & Astronomical Functions
Beyond the typical perpetual calendar displays for date, day, month, and year, the movement also includes astronomical moonphase indicators and semi-Gregorian complications—tracking celestial cycles with remarkable precision.
Design and Construction — A Movement Born of R&D
Audemars Piguet started the project that would become the AP 1000 nearly a decade before its release, aiming to push the boundaries of integrated mechanical functionality. This was not merely about stacking complications, but engineering a unified, user-friendly architecture for everyday wear.
A standout innovation is the “Super-Crown” system, which allows the wearer to advance or reverse calendar settings without requiring external pushers—a rare blend of ergonomic design and mechanical ingenuity.
Further elevating the movement’s design, AP engineered its chiming and complication systems around optimized acoustic performance, mechanical efficiency, and visual harmony—crucial in a caliber with over a thousand moving parts.
Where You’ll Find It
The Caliber AP 1000 debuted in the Audemars Piguet Code 11.59 Ultra-Complication Universelle #RD4, a flagship model representing AP’s vision for modern haute horlogerie. These pieces sit at the pinnacle of the brand’s offerings, usually limited in production and commanding prices well into the seven-figure bracket.
Variants like the AP 1000SQ offer a skeletonized design option, allowing collectors to admire the intricacy of the movement’s architecture from both dial and case back.
Why the AP 1000 Matters
The Audemars Piguet Caliber AP 1000 is not simply another movement—it is an achievement in mechanical integration. In an era when many high complications are modular or partially outsourced, the AP 1000 stands as a fully developed in-house unit that mixes traditional craftsmanship with cutting-edge engineering.
For collectors and enthusiasts, it represents the apex of contemporary watchmaking: technical bravura, artisanal finishing, and functional ambition brought together in a wristwatch caliber unlike most others ever made.
