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 4.5 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.

Audemars Piguet
In the Vallée de Joux — cradle of Swiss high horology — two young watchmakers joined forces in 1875. Their names were Jules-Louis Audemars and Edward-Auguste Piguet. From that moment on, Audemars Piguet has remained fiercely independent, family-owned, and uncompromising in its vision of what fine watchmaking should be.
Among the elite houses of horology, AP is the rebel artist. Innovative, daring, and forever rewriting the rules of design and engineering. In the 20th century, they were the first to create minute repeaters in wristwatch form. But it was in 1972 that Audemars Piguet changed watchmaking forever — with the birth of the Royal Oak.
A steel sports watch. With visible screws. An octagonal bezel. And a level of finishing usually reserved for gold. It was radical. Audacious. And in time, it became iconic.
Today, vintage watch collectors consider early Royal Oak references among the most desirable timepieces in the world. But the brand’s legacy runs deeper than one model. AP has always walked the fine line between artistry and technical prowess — whether through skeletonized perpetual calendars, ultra-thin tourbillons, or experimental case materials that push what a vintage watch can be.
To wear an Audemars Piguet is to wear confidence. It is for the collector who appreciates the avant-garde but demands heritage. Someone who seeks boldness, but never at the cost of substance. Someone who chooses a vintage watch not because it follows the rules — but because it rewrites them.
Audemars Piguet doesn’t just make watches. It creates icons that break molds — and then hand-finishes them to perfection.
Because tradition isn’t meant to be preserved under glass. It’s meant to evolve — beautifully, fearlessly, and with purpose.
