Audemars Piguet's Continued Innovation in Openworked Designs

Audemars Piguet consistently redefines excellence within its Openworked collection, where the intricate inner workings of the timepiece become a focal point of its aesthetic. Each creation demonstrates a meticulous approach that transcends mere dial cut-outs, offering a deep visual journey into the mechanical heart of the watch. This philosophy is evident in their latest offerings: two remarkable Royal Oak Openworked models, building upon a legacy of highly sought-after, complex designs that merge art and precision engineering.

The "Jumbo" Extra-Thin: A Masterpiece in Titanium and Bulk Metallic Glass

The latest iteration of the "Jumbo" Royal Oak Extra-Thin Openworked model retains its iconic 39mm case size and an elegant 8.1mm profile, previously available in white or yellow gold. This new version elevates its design by incorporating a titanium case complemented by super-hard, highly polished Bulk Metallic Glass (BMG) for its center links and bezel. The rhodium-plated bridges of the dial are harmoniously designed to create a tone-on-tone effect, enhanced by grey luminous hour markers and the signature Royal Oak hands. Powering this exquisite timepiece is the automatic Caliber 7124, a specially modified version of the 7121 movement found in standard "Jumbo" models, featuring extensively skeletonized bridgework to expose its mechanical beauty. This combination of innovative materials and refined mechanics showcases a new pinnacle of luxury and durability.

The 37mm Double Balance Wheel: Elegance in Yellow Gold

While the Double Balance Wheel movement is traditionally housed in 41mm Royal Oak cases, a 37mm variant has been available since 2018. The latest 37mm Double Balance Wheel Royal Oak introduces a captivating tone-on-tone yellow gold design. This model features a 37mm by 10mm yellow gold case, with corresponding yellow gold-toned bridges and silver-grey-toned rectangular 18k pink gold hour markers, paired with matching hands. The movement, Caliber 3132, incorporates two balance wheels working in tandem to enhance stability and precision, characteristic of AP's commitment to horological innovation. While slightly thicker due to its complex mechanics, this timepiece maintains the unmistakable elegance and presence of an Audemars Piguet creation. This particular rendition offers a unique blend of luxury and technical sophistication, appealing to those who appreciate a more compact yet equally impressive statement piece.

Pricing and Exclusivity of the New Releases

As with all exceptional Audemars Piguet Openworked timepieces, these new models are positioned as highly exclusive creations. The acquisition of these watches remains a privilege, with the "Jumbo" Extra-Thin priced at CHF 121,600 and the 37mm Double Balance Wheel at $103,000. Their availability is limited to Audemars Piguet boutiques, ensuring their status as covetable items among discerning collectors.

Reflections on Audemars Piguet's Design Philosophy

The "Jumbo" Royal Oak has long been celebrated for its impeccable balance and exceptional wearability. The introduction of these Openworked versions in new materials further refines an already near-perfect design. The titanium and BMG "Jumbo" offers enhanced scratch resistance and a lighter feel, demonstrating AP's commitment to both aesthetic and functional advancement. Similarly, the 37mm Double Balance Wheel in yellow gold represents a sophisticated option for collectors with smaller wrists, challenging traditional gendered watch sizing and offering a refined, all-gold aesthetic. These releases underscore Audemars Piguet's continuous pursuit of horological excellence, blending advanced engineering with timeless design.

Essential Details of the New Royal Oak Openworked Models

Both new models feature the distinctive Royal Oak design cues. The "Jumbo" Extra-Thin (Reference 16204XT) boasts a 39mm titanium and Bulk Metallic Glass case with a rhodium-toned openworked dial, blackened 18-carat white gold hour markers, and Royal Oak hands, all with luminescence. It is water-resistant to 50m and comes with an integrated titanium bracelet featuring BMG studs and a three-blade folding clasp. The 37mm Double Balance Wheel (Reference 15467BA) is crafted from 18k yellow gold, featuring a matching yellow gold-toned openworked dial, silver-grey toned 18k pink gold hour markers, and corresponding hands. It also offers 50m water resistance and an 18-carat yellow gold bracelet with an AP folding clasp.

Technical Specifications of the Movements

The "Jumbo" Extra-Thin is powered by the Calibre 7124, an automatic movement with hours and minutes functions. It measures 29.6mm in diameter and a mere 2.7mm in thickness, offering a 57-hour power reserve and operating at a frequency of 4Hz with 31 jewels. The 37mm Double Balance Wheel houses the Calibre 3132, also an automatic movement for hours and minutes. This movement has a diameter of 26.6mm and a thickness of 4.4mm, providing a 45-hour power reserve and a 4Hz frequency, with 38 jewels. Neither movement is chronometer certified, but both exemplify Audemars Piguet's dedication to precision and sophisticated mechanics.
