The Audemars Piguet Royal Oak Selfwinding Flying Tourbillon Openworked reference 26735SG.OO.1320SG.01 is a striking expression of haute horlogerie, combining the unmistakable Royal Oak design with an innovative 18kt Sand Gold alloy and an intricate openworked movement. Measuring 41mm in diameter, the octagonal case showcases the characteristic architectural lines of the Royal Oak while introducing a subtle golden-sand tone that shifts between the warmth of rose gold and the cooler character of white gold. At the heart of this exceptional timepiece is a self-winding flying tourbillon movement, making it as technically impressive as it is visually captivating.

The openworked dial provides an unobstructed view of the watch’s sophisticated mechanical architecture, revealing the intricate components of the movement beneath. Sand Gold and rhodium-toned elements create a refined two-tone aesthetic while maintaining a harmonious, monochromatic appearance. White gold hands and applied hour markers are finished with luminous material, ensuring clear legibility in low-light conditions. Surrounding the dial is the signature octagonal Sand Gold bezel, featuring the Royal Oak’s characteristic combination of brushed surfaces and polished chamfers. A sapphire crystal protects the dial while allowing the complex finishing and tourbillon mechanism to remain on full display.

Completing the design is the integrated Royal Oak bracelet, crafted from the same innovative Sand Gold alloy as the case. Its distinctive combination of satin-brushed and polished surfaces emphasizes the bracelet’s geometric construction and complements the angular lines of the case. The bracelet is secured by an Audemars Piguet folding clasp, providing a secure and refined fit on the wrist. The use of Sand Gold throughout the case and bracelet creates a cohesive appearance, while the subtle coloration of the alloy gives the watch a distinctive presence without the more traditional yellow or rose-gold appearance.

Turning the watch over reveals a transparent sapphire caseback, offering another perspective on the finely finished automatic movement. The self-winding Audemars Piguet Calibre AP 2950 features a flying tourbillon escapement and displays meticulous haute horlogerie finishing, including satin brushing, circular and sunray finishes, snailing, polished chamfers, and carefully executed vertical and horizontal brushing. The tourbillon is positioned at 6 o’clock and forms an integral part of the openworked architecture. The movement operates at 21,600 vibrations per hour and provides approximately 65 hours of power reserve when fully wound. With a screw-down crown and 50 metres of water resistance, the watch combines sophisticated mechanical engineering with practical everyday protection.

The Audemars Piguet Royal Oak Selfwinding Flying Tourbillon Openworked Sand Gold 26735SG.OO.1320SG.01 represents a remarkable fusion of design innovation, precious-metal craftsmanship, and advanced watchmaking.
