Audemars Piguet Royal Oak Ref. 56023BA

Yellow Gold · Smooth Dial · Diamond Indexes · Circa 1980s

Some watches transcend their era. Others capture it perfectly.

The Royal Oak Ref. 56023BA belongs to the second category. Crafted in 18-carat yellow gold, powered by quartz and fitted with a smooth dial punctuated by diamond indexes, it is a Royal Oak that could only have been born in the 1980s. And that is precisely what makes it so interesting today.

From Genta's revolution to a complete collection

When Gérald Genta designed the original Royal Oak in 1972, he challenged almost every convention of Swiss luxury watchmaking — exposed screws, octagonal bezel, integrated bracelet, and steel treated with the attention normally reserved for precious metals.

A few years later, Jacqueline Dimier played a central role in expanding Genta's concept into a true collection. Her 35 mm Ref. 4100 of 1977 established a proportion that would define vintage Royal Oak design. The 56023, introduced in 1982, belongs directly to this evolution: it preserved the architecture and presence of the Royal Oak while embracing the technology then transforming watchmaking — quartz.

Quartz, when quartz meant the future

To understand the 56023, it has to be viewed from 1982, not from today.

The rise of quartz coincided with economic and financial crises and helped plunge Swiss watchmaking into the most serious disruption in its history. For Audemars Piguet, the question went to the heart of the manufacture's identity: on one side, generations of mechanical expertise; on the other, the curiosity and innovation equally characteristic of the maison.

AP had been exploring quartz as early as 1969. It reached 35 mm in 1982 with the new Calibre 2506. For the first time, "mechanics and quartz crossed paths" — a customer could choose Royal Oaks of essentially the same design, but with fundamentally different technologies inside.

The Ref. 56023 stood directly at that intersection: one of Switzerland's most traditional manufactures placing the technology transforming its industry inside one of the most revolutionary designs of the previous decade.

A Royal Oak without the Tapisserie

Then there is the dial.

The Tapisserie pattern is so closely associated with the Royal Oak that it is easy to imagine it as immutable. Historically, it was not. This 56023BA, with its smooth dial and diamond indexes, changes the character considerably — the face becomes calmer and more refined; the diamonds provide discreet flashes of light against an otherwise restrained surface.

The industrial architecture remains, but its expression is different. It sits somewhere between sports watch and jewellery watch, industrial design and precious object.

From the Audemars Piguet archives

Very 1980s. In the best possible way.

By the 1980s, luxury had changed. Yellow gold no longer needed to hide beneath a cuff, technology had become aspirational, and luxury was increasingly something to be seen rather than whispered. A full-gold Royal Oak with diamond indexes and a quartz movement belongs perfectly to that world.

Yet the 56023 never feels excessive. Its 35 mm proportions keep everything under control.

There is a lot of gold, but not a lot of watch.

A Royal Oak wears larger than its diameter

A Royal Oak wears larger than its diameter suggests. The 56023 feels compact rather than diminutive — its slim construction sits close to the wrist, while the full yellow-gold bracelet provides more than enough presence.

After decades of increasingly large luxury watches, those proportions feel remarkably contemporary again.

Collecting the other Royal Oak

For years, collecting Royal Oaks meant following a familiar hierarchy: Jumbo, steel, mechanical, Tapisserie. References such as the 56023 tell another part of the story — the more adventurous side of the collection.

It does not recreate the original Royal Oak of 1972. It shows what happened when that idea was allowed to evolve with its time.

It is unmistakably a Royal Oak, yet it does not look like the Royal Oak everyone expects.
