The Audemars Piguet Royal Oak Selfwinding ref. 15510ST.OO.1320ST.06 is a 41 mm stainless-steel model distinguished by its “Bleu Nuit, Nuage 50” Grande Tapisserie dial, a shade closely connected to the colour used on the original Royal Oak introduced in 1972. The integrated steel bracelet, octagonal bezel and alternating brushed and polished surfaces preserve the architectural character that has defined the collection for more than five decades.
Inside is Audemars Piguet’s selfwinding calibre 4302, a modern manufacture movement operating at 4 Hz and offering approximately 70 hours of power reserve. It displays hours, minutes, central seconds and the date, while the sapphire caseback allows the movement and its finishing to remain visible.
Reference 15510ST.OO.1320ST.06 represents the contemporary evolution of the classic steel Royal Oak Selfwinding. Its combination of the iconic blue dial, current 41 mm proportions and calibre 4302 makes it particularly relevant for buyers seeking the core Royal Oak design in one of its most recognizable modern configurations.
