A replica AP skeleton is a Royal Oak with an openworked dial and movement, where the inner workings are visible from the front rather than hidden behind a solid dial. The look is unmistakable — bridges, gears, and balance wheel on full display. It is also the hardest category in the AP replica market to execute well, because the movement itself is the visible product. This guide covers the two references worth buying (15407 and 15305), the factories that make them, how to verify a genuine openworked movement from a fake, and current pricing. If you are new to AP replicas, read the complete Audemars Piguet replica guide first.
Key Takeaways
- Skeleton replicas expose the movement through the dial — nothing is hidden.
- The 15407 (41mm) and 15305 (39mm) are the references worth buying.
- APS and ZF are the only factories producing acceptable skeleton replicas.
- Prices run $1,200–$2,000; anything under $800 is a decal, not a skeleton.
- Finishing quality (anglage, perlage, bridge skeletonization) is the deciding factor.
- Genuine 15407ST trades at $180,000–$250,000 — replica is under 1% of that.
- Skeleton watches are fragile — no sports, no magnets, no water.
What Is a Skeleton AP Replica?
A skeleton AP replica is a Royal Oak with an openworked movement — the bridges and mainplate are cut away so light passes through the movement, making it visible from the front of the watch. Where a standard Royal Oak hides the movement behind a tapisserie dial, a skeleton exposes it as the design itself.
Three elements define a skeleton AP:
- Openworked movement. The bridges and mainplate have material removed to reveal the gear train, balance wheel, and barrel.
- Skeletonized dial. The dial itself may be removed entirely or reduced to a thin ring holding only the hour markers.
- Hand-applied finishing. Every exposed bridge edge requires anglage (beveled edges), and the mainplate requires perlage (circular graining). This finishing is what separates a well-made skeleton from a poorly made one.
Audemars Piguet’s genuine skeleton Royal Oaks include the 15407 (41mm, current), the 15305 (39mm, discontinued), and the 26522 (tourbillon). The 15407 is the most-replicated. Browse the Royal Oak collection to see current stock.
The Two References Worth Buying
| Reference | Size | Years Made | Movement | Replica Availability |
|---|---|---|---|---|
| 15407ST | 41mm | 2016–present | Caliber 3132 | Excellent (APS) |
| 15407OR | 41mm | 2016–present | Caliber 3132 | Good (ZF) |
| 15305ST | 39mm | 2010–2016 | Caliber 3129 | Limited (JF) |
| 26522CE | 41mm | 2020–present | Caliber 2988 (tourbillon) | Rare (APS) |
The 15407 — Current Flagship
The 15407 is the reference most buyers want. It uses the Caliber 3132, an openworked 3120 derivative with the same dimensions but cut-away bridges. Both steel (15407ST) and rose gold (15407OR) versions exist. The steel version is the closest replica to the genuine in appearance and the most available.
For a detailed look at the movement and how it is replicated, see the AP super clone guide.
The 15305 — Smaller, Discontinued
The 15305 is the 39mm predecessor to the 15407. Its smaller size suits wrists under 7 inches and its discontinued status makes the replica market thinner — JF is the main producer. If you want a Jumbo-sized skeleton, the 15305 is the option.
The 26522CE — Tourbillon Skeleton
A tourbillon skeleton with a black ceramic case, the 26522CE is the most complex skeleton in the replica market. Only APS produces an acceptable version, at $1,800–$2,500. Expect a genuine-clone openworked movement with visible tourbillon cage.
How Skeleton Movements Are Replicated
Replicating a skeleton movement is the hardest task in the replica industry. Factories take one of three approaches:
Approach 1 — True openworked clone 3120. The factory takes its existing clone 3120, machines away the same bridge material the genuine 3132 has removed, applies anglage to the exposed edges, and re-finishes the mainplate with perlage. This is the top-tier method. Used by APS and ZF.
Approach 2 — Openworked 2824. A cheaper approach: take an Asian 2824, cut away portions of the rotor and bridges, and mount it under a skeleton dial. The result shows a mechanical movement but with a bridge layout that does not match the genuine 3132. Common on $800–$1,200 builds.
Approach 3 — Decal dial. No openworking at all. A printed or laser-cut dial overlay creates the appearance of a skeleton movement. There is no visible mechanical depth. Common on anything under $800.
To tell them apart, use a loupe and look for depth — a true skeleton shows gears at multiple depths and light passing through the movement. A decal is flat.
Factory Quality: APS, ZF, JF
| Factory | Skeleton Strength | Weakness | Best Reference |
|---|---|---|---|
| APS | Best bridge finishing, best anglage | Higher price, limited stock | 15407ST, 26522CE |
| ZF | Good rose gold tone, solid finishing | Bevels less sharp than APS | 15407OR |
| JF | 15305 availability | Bridge cutting less precise | 15305ST |

AP Skeleton Replica Price Guide 2026
| Model | Factory | Movement | Price |
|---|---|---|---|
| 15407ST Steel Skeleton | APS | Openworked clone 3120 | $1,200–$1,500 |
| 15407OR Rose Gold Skeleton | ZF | Openworked clone 3120 | $1,400–$1,800 |
| 15305ST 39mm Skeleton | JF | Openworked clone 3120 | $1,200–$1,500 |
| 26522CE Ceramic Tourbillon | APS | Openworked clone 2988 | $1,800–$2,500 |
| Budget skeleton (decal) | Unknown | 2824 with overlay | $600–$900 |
Anything marketed as “skeleton” under $800 should be treated as a decal until proven otherwise.
How to Verify a True Skeleton Replica
Five checks, in order of reliability:
- Look for depth. Under a loupe, a true skeleton shows gears at three or more depth planes. A decal is flat.
- Check bridge edges. Anglage — the beveled edge of each bridge — should be polished and consistent. Machine-stamped edges look rounded and dull.
- Inspect the balance wheel. It should be visible and oscillating. If you cannot see it move, the movement is fake.
- Weigh the watch. A skeleton Royal Oak weighs less than a solid-dial equivalent. Genuine 15407ST weighs ~150g. Super clones weigh 140–150g. A decal on a heavy case will be over 165g.
- Photograph the case back. The movement should be visible from both sides and look consistent.

Care for a Skeleton Replica
Skeleton watches are more fragile than solid-dial Royal Oaks for two reasons: the movement is exposed to dust, and the openworked bridges have less material and are easier to damage.
Do:
- Wear in low-impact settings (office, dinner, events).
- Store in a dust-free watch box.
- Service every 3–4 years instead of the standard 4–6.
- Handle gently when setting the time or winding.
Don’t:
- Wear while playing sports, moving furniture, or doing yard work.
- Expose to strong magnetic fields (speakers, magnets, MRI).
- Wear in water. Skeleton replicas typically have the same 3ATM rating as solid AP replicas, but the exposed movement is more vulnerable to moisture ingress if the seal fails.
- Use ultrasonic cleaners.
Conclusion
The AP skeleton replica market in 2026 is small and expensive compared to solid-dial Royal Oaks. Two references matter: the 15407 (41mm) and the 15305 (39mm). APS leads for the 15407ST; ZF is the choice for the 15407OR rose gold. Prices start at $1,200 for a true openworked clone and reach $2,500 for the 26522CE tourbillon.
If you are deciding between a standard super clone and a skeleton, buy the standard first. The skeleton is a statement watch — the movement is the point, and the maintenance burden is higher. Once you own a solid Royal Oak, the skeleton becomes the natural next step.
