The watch’s case — either in 18k rose gold or titanium —is 44 mm in diameter and a relatively modest 13.2 mm thick and features the octagonal bezel with hexagonal screws that is emblematic of the Royal Oak collection. In both versions, the openworked dial is ruthenium-toned with satin-brushed surfaces and ruthenium-treated subdials (chronograph minutes counter at 3 o’clock, small seconds counter at 9 o’clock). The applied hour markers and Royal Oak-style hands are made of gold and coated with Super-LumiNova.
The watch’s manufacture movement, manual-winding Caliber 2936, consists of 299 parts, including 28 jewels, and has a frequency of 21,600 vph and a power reserve of 72 hours. Equipped with both a chronograph function and a tourbillon — and visible through glareproofed sapphire crystals in both the front and back of the case — this openworked movement boasts hand-sculpted curves and hand-finished decorations on its plates and bridges, highlighted by satin-brushed surfaces and polished, beveled edges.
The Audemars Piguet Royal Oak Tourbillon Chronograph Openworked is mounted on the classical Royal Oak bracelet, in either rose gold or titanium, and also comes with an additional strap made of gray alligator leather. Available at Material Good and other Audemars Piguet authorized retailers, the model in rose gold is priced at $297,000 and the titanium version is priced at $261,000.
