The term Audemars Piguet Ultra-Complication refers to the brand’s most technically ambitious timepieces, which typically combine a minimum of three classic high complications—such as a minute repeater, perpetual calendar, and split-seconds chronograph—into a single, magnificent movement. These creations are the ultimate expression of Audemars Piguet’s historical technical skill, proving their mastery over the most challenging elements of horology. Every Audemars Piguet Ultra-Complication Watch represents years of dedicated research and development, often resulting in patents for new mechanical solutions.


The Research and Development Series: RD#4

The pinnacle of the modern Ultra-Complication line is the revolutionary Audemars Piguet Code 11.59 Ultra-Complication Universelle RD#4. This timepiece, which debuted in the Code 11.59 line, integrates over 40 distinct functions, setting a new benchmark for integrated complexity. A major component of this watch is the innovative Audemars Piguet Supersonnerie technology, which drastically enhances the volume, clarity, and resonance of the minute repeater, making it audible even through the modern watch case. The integration of this vast complexity within the recognizable Code 11.59 architecture makes the Audemars Piguet RD#4 one of the most significant watches in contemporary horology.

Defining the Grande Complication Standard

Before the modern RD series, Audemars Piguet was famous for producing traditional Grande Complication Audemars Piguet models, which typically housed the three essential complications. Today, this ultra-complex category also includes specialized modern innovations like the Audemars Piguet Concept Laptimer, which features a dual-chronograph mechanism allowing successive lap times to be recorded instantly. Watches like the Audemars Piguet Laptimer demonstrate the brand’s commitment to applying ultra-complexity not just to traditional functions, but also to highly specific, modern uses that push mechanical performance limits.

Rarity and Value

These unique pieces are produced in extremely limited quantities, often as one-off or bespoke creations, making the AP Ultra-Complication Price astronomical and largely irrelevant to the standard retail market. Their value is determined by the rarity of their movements, the level of hand-finishing, and their historic significance. These watches are rarely available, and when they do appear, they command prices that place them among the most expensive timepieces in the world.
