The short answer: nearly every fake Audemars Piguet Royal Oak ref. 15002 fails at one of three places, the bezel screws, the Tapisserie dial, or the bracelet finish. Check those first, then verify the caseback numbers against an Extract from the Archives before any money changes hands.
What the ref. 15002 is
Audemars Piguet launched the Royal Oak in 1972 with the ref. 5402, and the line grew through dozens of references over the next three decades. The 15002 sits in the 1990s part of that catalog: a slim Royal Oak with an integrated bracelet, an octagonal bezel held by eight hexagonal screws, and a Tapisserie dial. It is a less common reference than the 15202 or the 15500, so caseback numbers and paperwork carry more weight here than they do on a mass-produced model. Confirm the variant first. Case metal, dial color, and case size differ across the 15002 family, and each one changes what correct looks like.
Inspection order
- Measure the case width and thickness with calipers, then set those numbers against the published specs for the exact 15002 variant you are checking.
- Count the eight bezel screws and look at the slot direction. Genuine heads sit flush with the bezel, carry a polished bevel, and the slots point in a consistent direction across all eight.
- Study the Tapisserie grid under a loupe. Genuine squares have sharp walls and even depth, while fake dials show a shallow pattern with rounded edges.
- Examine the date window. The aperture edges should be beveled with no printed border, and the date font should match the period.
- Compare the dial printing and the applied AP monogram. Look at stroke weight on the Audemars Piguet signature and at the relief height of the logo.
- Read the caseback engraving. Reference and serial numbers should be cut with sharp edges and a consistent font, not etched and fuzzy.
- Run a thumb along the bracelet. End links should sit flush to the case, the taper should be even, and the brushing should run straight with no rounded edges.
- Have a watchmaker open the caseback. A genuine movement is signed Audemars Piguet, carries a gold rotor, and shows proper finishing. A Miyota, an ETA, or an unbranded movement settles the question.
Numbers and paperwork
A genuine 15002 carries a reference number and a serial number stamped into the caseback, and both should read cleanly under a loupe. The Extract from the Archives issued by the manufacture confirms the reference, the movement number, the case metal, and the original delivery date. Match the extract to the watch, not the other way around. A seller who cannot produce one, or who sends a scan with a serial number that does not match the case, ends the conversation there.
Weight and dimensions
A steel Royal Oak on a full bracelet feels dense and slightly top-heavy on the wrist. Counterfeits usually run light because the case walls and bracelet links are thinner than the drawings call for. Calipers tell you more than your hand does. Measure across the case at the bezel, measure thickness from caseback to crystal, and compare both numbers with the reference data before you accept any other explanation.
Counterfeit versus disclosed replica
These are two different products. A counterfeit is sold as a genuine watch, and that is fraud no matter how close the copy gets. A disclosed replica is sold as a replica, and the fair questions change: does the case measure the same, does the Tapisserie pattern match the period, does the bracelet taper correctly, and which movement sits inside. Ask for photos of the actual unit rather than a stock image, ask for the movement type in writing, and confirm the return window before payment.
Bottom line
Verify the reference and serial numbers first, since paperwork is the cheapest test you can run. Then move to the screws, the dial, and the bracelet, in that order. If a single check fails, stop. A genuine 15002 passes all of them.
