Audemars Piguet have always been keen to keep their finger on the pulse of culture, and so in 2023 they made an unofficial collaboration using their iconic Royal Oak an official collaboration by teaming up with Matthew Williams’ streetwear brand 1017 ALYX 9SM. In 2021 Williams’ brand joined forces with Parisian watch customizers MAD Paris to create a series of bespoke watches that reinvented the Royal Oak by introducing a minimalist aesthetic built upon a brushed metal dial and monochromatic aesthetic. Then, two years later, AP officially teamed up with 1017 ALYX 9SM to create five official collaboration references, four for sale to the public as a limited edition release, and one to be auctioned for charity. Offered here we have the limited edition time-only Royal Oak ref. 15550BA.OO.1356BA.02, made to only 194 pieces. Measuring 39mm in diameter and boasting a case that is only 9.1mm tall thanks its 4mm tall automatic cal. 5909 which features a commemorative 22kt yellow gold winding rotor that boasts an engraving of the 1017 ALYX 9SM logo as well as the indication of Newton's millimeter and the rotor’s weight in grams, which is a deliberate nod to the technical references indicated by Matthew Williams on the buckles he uses for his belts and other accessories. Featuring a vertically brushed golden dial with luminescent yellow-gold hands and the signatures "Audemars Piguet" in gold applique at 12 o’clock and "1017 ALYX 9SM" via stamp transfer at 6 o’clock, this timepiece’s aesthetic is immediately obvious as something special and outside of the realm of normality even for an avant-garde brand like AP.
