Spotlight: Audemars Piguet Royal Oak 15400ST, black dial

Produced from 2012 to 2019, the 15400ST scaled the Royal Oak to 41 mm while keeping the octagonal bezel, eight hexagonal screws and integrated bracelet of the 1972 original. Calibre 3120 offers 60 hours of reserve; the black Grande Tapisserie dial is the most classic of the three.
