A fake Audemars Piguet Royal Oak Concept 25979 is a replica of an early Royal Oak Concept, the openworked AP sports watch with an angular case and a visible tourbillon. Copies sell in several grades, from cheap alloy pieces with a printed dial to high-grade 1:1 builds that copy the case profile, the skeleton dial, and the tourbillon cage. The genuine reference is scarce and costly, which is the main reason the copy market pays attention to it.
What Is the Royal Oak Concept 25979?
The Royal Oak Concept was AP's answer to the question of what a Royal Oak could become with no limits on materials or finishing. It launched with a case that ignored the classic octagon and integrated-bracelet formula. The 25979 sits in that first group of Concept references, and like its siblings it was built in small numbers.
The line has a set of traits that every copy tries to match:
- Angular, oversized case with a stepped profile
- Skeleton dial that shows the movement from the front
- Tourbillon, on some versions paired with a chronograph or GMT
- Lightweight or exotic case materials
- Rubber or composite strap on many versions
Because the design is unusual, a copy stands out fast. Buyers who know the classic Royal Oak spot the shape, but they may miss the small details that separate a real Concept from a fake one.
How Are Fake 25979 Watches Made?
Factories work in tiers, and the price tracks the number of real parts and the hours of finishing.
Tier 1: Budget Copies
These use a quartz or low-grade automatic movement in a plated alloy case. The dial is printed or stamped, the tourbillon spot is often a fake opening with a spinning weight, and the strap is thin rubber or PU. Weight is the giveaway, since a budget copy feels light and hollow.
Tier 2: Mid-Range Copies
Steel cases, a decorated automatic movement, and a sapphire crystal appear at this level. Finishing is machined rather than hand-applied, so the bevels look flat under a loupe. These watches can look right from across a room and wrong up close.
Tier 3: High-Grade 1:1 Builds
Top-tier builds copy case dimensions, thickness, lug geometry, and dial texture from a genuine sample. Some use a working tourbillon movement, which pushes the price far above the other tiers. Even these tend to fail on the caseback engraving, the font on the rotor, and the hand-polished chamfers.
How Do You Spot a Fake Royal Oak Concept 25979?
Five checks cover most of it.
1. Check the Case Profile and Bevels
Run a finger along the edge of the case. A real AP has a crisp, even bevel that catches light in one continuous line. Fakes show a rounded or uneven edge, and the brushed and polished surfaces meet at a soft boundary.
2. Check the Dial and Skeleton Work
Look at the open areas of the dial. Genuine Concept dials have clean edges on every bridge and wheel, with no tool marks or burrs. Copies show rough cuts, mismatched screw heads, and hands that sit too high or too low.
3. Check the Tourbillon
A real tourbillon rotates the balance and escapement inside a cage, once per minute. In cheap copies the cage does not rotate at all, or the balance spins in place with no cage around it. Watch the opening for 60 seconds and count the rotation.
4. Check the Weight and Feel
Weigh the watch if you can. Plated alloy and cheap steel land far under the expected mass for a case this size in titanium, forged carbon, or gold. The crown action tells a story too, because real AP crowns turn with a firm, oiled feel.
5. Check the Caseback and Papers
Serial numbers, reference stamps, and engraving depth are the hardest things to copy. Compare the font on the caseback to AP's own reference photos. Fake papers and boxes are common, so a full set proves nothing on its own.
What Does a Fake 25979 Cost?
Price moves with the tier, not with the model name. Budget copies sell for the price of a mid-range fashion watch, mid-tier builds cost a few hundred dollars, and top-tier pieces with a working tourbillon cost the most. The gap reflects the movement and the finishing, not the name engraved on the dial.
What Should You Ask Before Buying?
- Which movement is inside, and is the tourbillon functional?
- What are the case diameter, thickness, and lug width?
- Is the crystal sapphire or mineral glass?
- Can you send a video of the tourbillon running for 60 seconds?
- Are the photos of the actual watch or a stock image?
- What is the return policy if the watch does not match the listing?
Ask for video with the watch on a scale. Weight plus running tourbillon footage removes most of the guesswork before money changes hands.
FAQ
Is the Royal Oak Concept 25979 Still Made?
AP's current catalog has moved on, and the 25979 is not a current model. Check the reference against AP's own records before you treat any listing as accurate, since secondary sources describe the details in different ways.
Do All Fake 25979 Watches Have a Working Tourbillon?
No. Cheap copies use an open aperture that mimics the look. Mid-tier copies may use a real tourbillon movement with rough finishing. Only the top tier gets close, and even then the cage is a copy of a copy.
Can a Watchmaker Tell a Real Concept 25979 From a Fake?
Yes, and it takes minutes on a bench. The caseback comes off, the movement decoration is visible, and the finishing on the bridges and screws does not match AP's standard. A trained eye also spots the wrong fonts and the wrong case thickness.
Why Do People Buy Fake Royal Oak Concept Watches?
The real watch is rare and expensive, and the design is loud. A copy lets someone wear the shape without the price. The trade-off is resale value, service support, and the risk of a poorly built watch.
Quick Recap
Judge a fake 25979 by the case bevels, the dial finish, the tourbillon action, the weight, and the caseback engraving. Tier matters more than listing photos. A seller who answers movement questions with specifics and sends running video is a better sign than any certificate in the box.
