Royal Oak DNA, Refined in Two-Tone

A perfect blend of sport and sophistication, the Audemars Piguet Royal Oak Ref. 4100SA delivers the legendary Gerald Genta design in a beautifully balanced 36mm case — one of the most wearable and versatile Royal Oak references ever made.

Crafted in stainless steel and 18k yellow gold, this two-tone execution exudes subtle luxury while keeping the industrial spirit of the original intact. The grey tapisserie dial, untouched and in flawless condition, features an applied gold AP logo, luminous stick markers, and matching hands — all showing even, natural aging that enhances its vintage character.

With its iconic octagonal bezel, perfectly finished bracelet, and 1980s provenance, this is a Royal Oak for the true connoisseur — rarer than the jumbo, and just as coveted in the right circles.
