The 26515OR is where Audemars Piguet stops making watches and starts making arguments for haute horlogerie. This replica royal oak 26515OR presents the double balance wheel openworked movement through a fully skeletonised dial, exposing every bridge, wheel, and spring in the Cal. 3132. Housed in 18K rose gold at 41mm, it is a piece that demands close inspection. The dual balance wheels, visible on the dial side, operate in parallel to improve rate stability. This is not a daily wearer. It is a statement about mechanical ambition.
Two Balance Wheels, One Purpose
The double balance wheel is not a gimmick. Two balance wheels connected by a shared differential absorb positional errors more effectively than a single regulator. When one wheel encounters gravitational interference in a given position, the other compensates. The result is a flatter rate curve across the six standard testing positions.
Audemars Piguet developed this architecture specifically for the Royal Oak platform. The Cal. 3132 measures approximately 5.5mm in height, keeping the overall case thickness at 10.4mm despite housing considerably more mechanical complexity than a time-only movement.

Rose Gold and Open Architecture
The 18K rose gold case and bracelet give the 26515OR a warmth that complements the mechanical theatre of the skeletonised dial. Every bridge in the Cal. 3132 receives hand-applied bevelling and circular graining, finishing techniques that are fully visible through both the dial and the sapphire caseback. There is nowhere to hide imperfection in an openworked movement, which is precisely the point.
This replica royal oak 26515OR sits at the intersection of complication and design. It functions as hours and minutes only, stripped of the date complication to preserve dial symmetry. For those drawn to the skeleton aesthetic but preferring stainless steel, the 15407ST openworked offers the same visual intensity at a different price point.
