Audemars Piguet Royal Oak Ref. 4100BA – 1980

The Classic Royal Oak Refined in 18k Yellow Gold

When the Ref. 4100 debuted in 1977, it marked a pivotal evolution in the Royal Oak lineage — the first to feature a central seconds hand and a more wearable 35 mm case, designed for those who found the Jumbo models too large.

Our 1980 example, the 4100BA, is the full 18k yellow gold version and comes in absolutely stunning condition. The grey petit-tapisserie dial, produced by Stern Frères, is a work of art — bearing all the rich texture and timeless charm that defines early Royal Oaks.

Powered by the automatic Caliber 2123, based on Jaeger-LeCoultre’s ultra-thin movement and custom-finished by AP, it offers performance and prestige in equal measure.

Paired with its original Royal Oak 18k gold bracelet and a signed AP clasp, this reference is a quintessential blend of sport and elegance — a golden icon for serious collectors, especially with the original Extract from Archives from Audemars Piguet.

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.
