Overview

Introduced in 2016, the Royal Oak Double Balance Wheel Openworked features a 41mm stainless steel case and an intricately skeletonized dial that showcases its complex inner workings. The timepiece is powered by the self-winding Caliber 3132, which incorporates a patented double balance wheel mechanism aimed at enhancing precision and stability. This model stands out with its pink gold-toned inner bezel and openworked movement, offering a striking contrast against the stainless steel architecture.

Design and Craftsmanship

Audemars Piguet's meticulous attention to detail is evident in the design of this watch. The stainless steel case features the signature octagonal bezel secured by eight hexagonal screws, a hallmark of the Royal Oak collection. The openworked dial reveals the intricate mechanics beneath, with a pink gold-toned inner bezel adding a touch of warmth and luxury. The movement bridges are meticulously hand-finished, showcasing chamfered edges and polished surfaces that reflect the brand's commitment to superior craftsmanship.

Movement and Performance

At the heart of this timepiece lies the self-winding Caliber 3132, a movement that features a unique double balance wheel mechanism. This innovative design involves two balance wheels and balance springs mounted on the same axis, working in harmony to improve timekeeping precision and stability. Operating at a frequency of 21,600 vibrations per hour, the movement offers a power reserve of approximately 45 hours. The openworked design not only enhances the watch's aesthetic appeal but also allows for a captivating view of the oscillating balance wheels in action.

Features and Complications

While the primary focus of this timepiece is its innovative double balance wheel mechanism, it also includes practical features such as a central hours and minutes display, along with a small seconds sub-dial at the 8 o'clock position. The absence of additional complications ensures a clean and uncluttered dial, allowing the wearer to fully appreciate the intricate openworked design. The watch is water-resistant up to 50 meters, providing a degree of protection suitable for daily wear.
