Audemars Piguet Royal Oak Double Balance Wheel Openworked Review
The Audemars Piguet Royal Oak Double Balance Wheel Openworked is one of the most visually captivating Royal Oak models ever introduced. Presented at SIHH 2018, this model pairs the shimmering Frosted Gold finish with the mechanical depth of an openworked double balance wheel movement. The combination of traditional craftsmanship and architectural skeletonization makes it a standout creation in the Royal Oak family. For background on the Royal Oak line, you may refer to the official brand heritage at Audemars Piguet.
Case Design and Frosted Gold Craftsmanship
The 37 mm case size draws inspiration from earlier Royal Oak proportions, while looking visually larger thanks to the bright, shimmering Frosted Gold surface. This finishing technique was developed together with Italian jeweler Carolina Bucci, using a hand-hammering method that reflects light like a field of tiny diamonds. The signature octagonal bezel and integrated bracelet are enhanced by mirror-polished bevels, creating a dramatic contrast with the frosted texture.
Openworked Dial and Mechanical Architecture
The dial reveals nearly the entire movement, showcasing the mechanical interaction between the components. At 1 o’clock, the skeletonized barrel displays its winding state. At 3 o’clock, the visible gear train demonstrates the transmission of power. The most notable feature lies at 8 o’clock—the double balance wheel mechanism, a major technical innovation by Audemars Piguet.
The emerald-cut applied hour markers add a three-dimensional effect, and the open layout offers constant visual motion. Despite its highly technical appearance, the watch maintains a traditional three-hand configuration.
Caliber 3132 and Double Balance Wheel Technology
The Royal Oak Double Balance Wheel Openworked is powered by the automatic Caliber 3132, introduced in 2017. At only 5.57 mm thick, it is an ultra-thin movement with a modern interpretation of precision regulation. The dual balance wheel system consists of two balance wheels mounted on the same axis, operating simultaneously to counteract each other’s positional errors. This reduces rate deviations caused by gravity and wrist movement, reportedly improving accuracy by up to 30 percent.
The movement offers a 45-hour power reserve and beats at 21,600 vibrations per hour. With 38 jewels and meticulous hand-finishing, it represents the brand’s dedication to both functionality and aesthetics.
Variants, Price, and Wearing Experience
Two primary versions are available: 18K white gold and 18K rose gold, both featuring the Frosted Gold finish. The official retail price was USD 76,000 at launch, positioning it among the most striking and collectible mid-sized Royal Oak references of its generation.
The integrated gold bracelet maintains a comfortable fit while enhancing the luminous appearance of the entire watch. With 50 meters of water resistance, sapphire crystals on both sides, and a screw-down crown, the piece remains practical enough for regular wear.
