Audemars Piguet Royal Oak Selfwinding 15550BA Alyx

This Audemars Piguet Royal Oak Selfwinding, ref. 15550BA.OO.1356BA.02, is part of a striking collaboration between AP and American designer Matthew Williams, founder of the fashion label 1017 ALYX 9SM, bringing a fashion-forward sensibility to the Royal Oak's haute horlogerie foundations. Crafted entirely in 18-carat yellow gold, the 37mm case houses a monochromatic yellow gold dial finished with vertical satin-finishing, paired with matching yellow gold Royal Oak hands treated with luminescent coating. The all-gold execution gives the octagonal case and bracelet a bold, tonal look rather than the more common two-tone or contrasting-dial approach, and it's completed with a glareproofed sapphire crystal and caseback plus an 18-carat yellow gold bracelet fitted with an AP folding clasp.

Powering the watch is the Calibre 5909, a selfwinding movement driving simple hours, minutes and centre seconds functions, with a 60-hour power reserve. Water resistance sits at 50 metres. Produced as a limited edition of 194 pieces, this reference sits at the intersection of streetwear-inflected fashion design and traditional fine watchmaking, making it a distinctive pick for collectors drawn to the Royal Oak's iconic silhouette wrapped in a rarer, design-collaboration story rather than a standard production model.
