Audemars Piguet Octagon 18k Onyx Diamond 1970s
Black Diamond Elegance — Audemars Piguet in 18k Onyx White Gold
This rare Audemars Piguet from the late 1970s is an exercise in quiet opulence. Crafted entirely in 18k white gold, its unique octagonal-elliptical case houses a flawless black onyx dial punctuated by twelve factory-set diamond indexes — understated luxury at its finest.
The ultra-thin Calibre 2003 lies within a case just 4.5Â mm thick. The integrated white gold bracelet flows effortlessly around the wrist, offering comfort that matches its architectural refinement.
Extremely rare in this configuration — and preserved in outstanding condition — this Audemars Piguet is more than a timepiece: it’s a wearable sculpture of modernist craftsmanship and enduring elegance.
