For over a century, Audemars Piguet has devised endlessly inventive horological masterpieces. Discover the intricacies of the craft - the ways history influences design, the methods by which components are handcrafted, and the ever-present focus on excellence.
The openworked extra-thin Royal Oak Tourbillon epitomizes the expression of our savoir-faire.
Designing & Developing
Envisioning the future of a classic.
We set out to evolve the classic Royal Oak DNA through a bold new expression in the Openworked Extra-Thin Royal Oak Tourbillon.
Bringing visionaries and virtuosos together
Housed under one roof, our design and development teams work in concert over the course of 3-5 years to turn an idea into a perfect, functioning timepiece.
Design process in every Audemars Piguet timepiece is profoundly identifiable across the collections.
Computer designers and art directors collaborate to evolve the sketch into a more concrete vision.
A 10:1 scale model is produced from the CAD model. This draws attention to any issues before the smaller prototype version is made.
Depending on the complexity of the movement, one to five prototypes are performed to validate the caliber.
It takes on average one month for watchmakers and 3D engineers to create a finished prototype.
We put as much thought into building our work environment as we do into producing our timepieces.
Every part requires a setting that is uniquely designed to produce perfection.
Making The Components
Hand-crafted inside and out.
In our pursuit of perfecting timepieces by hand, we meticulously craft each piece with precision and expertise.
The Royal Oak
Several steps are involved in finishing every skeletonized mainplate, each carried out by hand: flanking & beveling, perlage and polishing.
The purpose of openworking is to enhance transparency and aesthetic appeal. Openings are made in certain parts of the watch to reveal the beauty of the mechanism, without touching the vital parts that ensure smooth running.
Beveling is a meticulous finish that greatly contributes to the beauty of the mainplate by highlighting the rim.
This process eliminates the edges between the surface and flanks to form a bezel that will subsequently be polished.
Perlage is a type of decoration used on bridges, bars, plates, recesses and dials. A turning rod marks the surface with extremely close concentric or even overlapping lines to form the motif.
Linear graining creates fine lines and enhances brilliance.

This decoration begins by sandblasting the case-middle to a desired texture.
Lapping is next applied to reveal the facets.
The bezel is then polished with a special paste, revealing the luminosity of the Royal Oak.
The facets are varnished for protection against the elements.
Finally, a satin decoration is applied to the top of the bezel to give the Royal Oak its distinguished look.
When the case-middle, the angles, and ridges are matched with its bezel, the watch can be judged for perfection.
The comfort of the bracelet is guaranteed by the shape of the intermediate links
and the mastery with which they are made.
The distinctive “bathtub” shape of the hands and hour-markers means the luminescent material may be poured rather than applied, thus ensuring a more attractive finish.
Classic Royal Oak
The dial’s square and lozenge motif is created by machines which perform guillochage, a highly intricate way to capture the light and accentuate a timepiece’s geometric relief.
Audemars Piguet's constant quest for innovation has propelled it to the forefront of brands using high-tech and avant-garde materials.
The Royal Oak bezel undergoes 28 operations before reaching its final emblematic octogonal shape.
The Historical Evolution of the Royal Oak
From Avant-Garde to Icon, take a journey through time to discover a spirit that endures.
The brass dial is engraved by a burin (a precision metalwork chisel) that reproduces the motif on a disc attached to the machine, like a pantograph.
Materials Used in the Royal Oak Collection
Composed of iron, chromium, nickel and molybdemum, steel boasts excellent corrosion resistance. To perfect the aesthetic appeal of stainless steel, Audemars Piguet has developed an exclusive surface treatment endowing the metal with a luminous appearance.
Audemars Piguet launched the world’s first stainless-steel luxury watch. In an era when gold was considered the only high-end option, it was a gamble. But it paid off with the birth of one our most iconic watches.
Extra-thin Royal Oak
Precious metal has always been a staple material in fine watchmaking. Pink gold is composed of 75% fine gold, along with 5% silver and 20% copper, the latter proportion varies according to the desired color intensity. Audemars Piguet also uses two other forms of gold: yellow and white.
Selfwinding Royal Oak
Platinum is 30 times more rare than gold, in fact it is the most exclusive metal in the field of fine watchmaking. It is also used in its purest form, at 95%. Its malleability makes it particularly difficult to handle.

No watchmaker uses carbon like Audemars Piguet. Based on an innovative method, 1mm diameter carbon wire strands are molded by extreme pressure and heat. Beyond its lightness, forged carbon offers the advantage of making parts with straight edges and sharp angles.
Audemars Piguet launched the world's first carbon luxury watch, the Royal Oak Offshore Alinghi Team.
Royal Oak Carbon Concept
Grade 5 titanium, the most resistant and robust variety on the market, is ultra-rugged and twice as light as steel. Titanium boasts strong chemical stability and is hypoallergenic.

Five Iconic Royal Oaks
It Was to Change the Face of Modern Watchmaking
Designed virtually overnight by the brilliant and experienced stylist Gérald Genta, the Royal Oak was a bold response to a request for an “unprecedented steel watch.” Initially met with a blend of astonishment and contempt, the Royal Oak soon established itself as an iconic model that was to change the face of modern watchmaking.

An Evolved Equation of Time
Ten years after releasing the first Equation of Time watch, Audemars Piguet presented this exceptional timepiece combining four celestial high complications: a perpetual calendar, a precision display of the lunar cycle, the equation of time (which displays the difference between “true” solar time and conventional time), and civil sunrise and sunset times.

Assembling The Watch
The final touch.
Several hundred parts come together under the eye of a skilled watchmaker. Putting them together is just the beginning of this precise and meticulous finishing effort.
Meticulous Attention to Detail, Defined
Each watchmaker starts by putting the timepiece together, testing it, taking it apart, polishing the sections, putting it back together and then doing it all over again until it is worthy of leaving the factory.
Only highly skilled and dedicated watchmakers achieve unparalleled results, like assembling the Royal Oak Grande Complication or Openworked Extra-Thin Royal Oak Tourbillon.
Casing up a Royal Oak timepiece is a decisive activity. Dial and hands are fitted on the movement before disappearing inside the case.
