Short answer
There is no faithful replica of reference 25979. The watch being copied is the Royal Oak Concept CW1 from 2002, a limited edition of 150 pieces built around a hand-wound Audemars Piguet movement with a selector crown, an openworked architecture and a case finished to a standard that no replica factory has matched. Nothing at replica money reproduces that. What gets advertised as a "25979" is usually a skeleton-dial watch in a Concept-shaped case, and sometimes a listing for a later Concept reference with the wrong number typed into the title.
What ref. 25979 actually is
The Royal Oak Concept CW1 arrived in 2002 for the Royal Oak's 30th birthday. Audemars Piguet made 150 of them. The case was a clean break from the 1972 design: an angular housing with exposed movement elements, a crown that clicks between winding, neutral and setting positions, and a dial that works as a view into the mechanics rather than a face. It has auction history behind it. It is a collector object, not a production watch, and collectors pay accordingly.
Why it barely exists as a replica
- Movement. The original is hand-wound and openworked with real depth between the bridges. Replicas use a stock automatic with decorative plates screwed on top, so the bridge shapes, the jewel positions and the dial depth are all wrong.
- Functions. A crown that genuinely switches between winding, neutral and setting is rare at any price point. Most reps have a crown that sets the time and a pusher that does nothing.
- Case. AP used lightweight alloys and finishing steps that cost more than an entire replica. Reps are steel, sometimes titanium-plated, and the brushing is shallower.
- Supply and demand. With so few genuine pieces in circulation, factories have little reason to tool up. The demand sits with later Concepts, which is what most "Concept" reps are actually copying.
If you still want one, inspect these
- Case profile. The Concept silhouette is not the standard octagonal Royal Oak. Ask for a side photo. The crown guard and case flank are where bad reps fall apart.
- Bezel screws. Eight of them, heads flush with the bezel, slots oriented consistently. Proud or randomly turned screws are a tell.
- Dial depth. A real skeleton shows layered gear teeth and jewels under the crystal. A rep dial is often a flat printed lattice with a shiny coating.
- Crown behavior. Ask for a video where the crown is pulled, turned and pushed back. If the seller will not record it, assume the selector is decorative.
- Crystal and coating. The genuine crystal has strong anti-reflective treatment and near-invisible edges. Rep crystals go milky at an angle.
- Caseback engraving. "25979" stamped on a caseback with the wrong shape means the listing is guesswork.
- Hardware. Clasp edges, spring bar fit and strap stitching separate the mid tier from the cheap tier more than the dial does.
Price reality
Skeleton-style Concept reps sit in the low hundreds, with better-finished examples reaching into four figures. Anything claiming a working selector crown, a genuine tourbillon or a Swiss movement should come with movement photos and a running video, and even then the money buys dial finishing and crystal quality, not mechanical accuracy. Paying a premium for a "25979" will not move you closer to the original, because the original's value lives in its movement.
Red flags in listings
- Photos lifted from press coverage of the genuine watch.
- "Swiss movement" with no movement shot and no video.
- Claims of a 1:1 clone of a 150-piece limited edition.
- Reference numbers that do not match the case shape in the same listing.
- Sellers who refuse timestamped photos or a short clip of the watch ticking.
