Where the Royal Oak Goes Extreme
The standard Royal Oak is a luxury sports watch. The Royal Oak Offshore is its bigger, bolder sibling. But the Royal Oak Concept is something else entirely: AP’s experimental platform where titanium meets tourbillons, forged carbon meets flying minute repeaters, and prices enter six-figure territory without apology. The Concept line exists to prove what’s mechanically possible when budget is irrelevant.
Key Concept References
Royal Oak Concept Flying Tourbillon (26589TI)
- Case: 41mm, Grade 5 titanium, openworked bezel
- Movement: Cal. 2950 (hand-wound, 72h, flying tourbillon visible at 6 o’clock)
- Dial: Fully openworked — the movement IS the dial
- Retail: ~$175,000
The entry-level Concept. The flying tourbillon (no upper bridge, cantilevered from below) rotates once per minute, visible through the skeletonized dial. The titanium case keeps weight manageable despite the 41mm size.
Royal Oak Concept Supersonnerie (26577TI)
- Complication: Minute repeater with patented soundboard technology
- Case: 44mm, titanium with ceramic strike guard
- Innovation: The caseback acts as a soundboard (like a guitar body), amplifying the repeater’s chimes to levels audible in a noisy room — solving the minute repeater’s traditional weakness (faint sound through solid gold cases)
- Retail: ~$650,000
The Supersonnerie took 8 years to develop. AP collaborated with the École Polytechnique Fédérale de Lausanne (EPFL) to model the acoustic physics of the case-as-soundboard concept. The result: the loudest, clearest minute repeater in the world.
Royal Oak Concept GMT Tourbillon (26580IO)
- Case: 44mm, forged carbon + titanium
- Complications: Flying tourbillon + GMT (second time zone)
- Dial: Openworked with GMT disc at 9 o’clock
- Retail: ~$250,000
Forged carbon (random carbon fiber pattern, each case unique) combined with a tourbillon and GMT. It weighs under 100g — lighter than most steel time-only watches — because forged carbon has the strength of steel at 1/5 the density.
Materials Innovation
The Concept line showcases AP’s materials R&D:
- Forged Carbon: Carbon fiber chopped into random short fibers, compressed under extreme heat/pressure. Each case has unique patterning — no two are alike. Originally developed for F1 suspension components.
- Cermet: Ceramic + metal composite. Harder than titanium, lighter than steel, grey in color. Scratch-resistant like ceramic but tougher (ceramic alone is brittle).
- Black Ceramic: Zirconium oxide, matte black, virtually scratch-proof.
- Sapphire: Full sapphire crystal cases (transparent) machined from single sapphire blocks. 100+ hours of CNC per case.
Concept vs Standard Royal Oak
| Factor | Concept | Standard (15500ST) |
|---|---|---|
| Price | $175,000-$700,000 | $27,000 |
| Materials | Titanium, carbon, ceramic, sapphire | 316L steel |
| Complications | Tourbillon, GMT, repeater | Time + date |

| Production | ~100-200/year total | ~10,000+/year |
| Daily Wearability | Low (delicate complications) | High |
Frequently Asked Questions
Is the Concept a good investment?
Concept references hold value well due to extreme rarity (100-200/year across all variants). The Supersonnerie has appreciated 30-50% since launch. However, the entry cost ($175K+) limits the buyer pool, making resale slower than standard Royal Oaks.
Can I wear a Concept daily?
The flying tourbillon variants: yes, with care (avoid impacts). The Supersonnerie: not recommended — the repeater mechanism is delicate. All Concepts should avoid sports, manual labor, and strong magnetic fields.
