Audemars Piguet 18k Automatic Black Diamond 1970s
Black Diamond Elegance — Audemars Piguet in 18k 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 dial punctuated by twelve factory-set diamond hour markers — understated luxury at its finest.
The ultra-thin Calibre 2121/1, one of Swiss watchmaking’s most revered automatic movements, lies within a case just 6 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.
