A fake Audemars Piguet Royal Oak 15510 is a copy of the 41 mm steel Royal Oak that AP released in 2022. The reference 15510ST replaced the 15500ST. Replicas of this model sit in the mid to high tier of the copy market. Top builds match the 41 mm case width, the 10.4 mm thickness, and the Grande Tapisserie dial pattern. They still fall short on movement construction, case back engraving, and bracelet finish.

What the Copies Get Right
Case diameter and lug shape come from a CNC case that follows the 15500 and 15510 profile. The 8-sided bezel takes 8 hexagonal screws. Sapphire with inner anti-reflective coating is standard on the better builds. Many sellers ship a display case back with a decorated automatic movement. The dial pattern is stamped or cut, and the date wheel uses a font close to the AP part.
Common Tells
Thickness is the first check. Many low and mid tier copies measure 11 mm to 12 mm. The genuine case measures 10.4 mm. The Calibre 4302 has a free-sprung balance, Geneva stripes on the bridges, black polished screws, and a gold rotor. Copies use plated base movements or a clone with decorative plates. Look at the screw slots, the engraving depth on the case back, and the polish on the bracelet chamfers. Soft chamfers with rounded edges point to a copy.
Weight is the second check. A genuine 15510ST on a full steel bracelet lands near 170 g. Ask the seller for a scale photo with the bracelet sized.
Movement Types in Copies
- Clone 4302: decorated to look like the AP caliber. Sellers claim 70 hours of reserve. Real reserve runs lower.
- Modified ETA 2824 or Seagull ST21: 38 to 42 hours of reserve, thicker movement, spacer ring inside.
- Miyota 9015: thin, 42-hour reserve, but rotor and bridge shapes do not match the 4302.
- Quartz: lowest tier. Case profile is often wrong and the tick is visible.
Price Tiers
- Low: $100 to $250. Plated movement, wrong thickness, thin bracelet.
- Mid: $300 to $650. Better case, Miyota or ETA base, dial stamping close to spec.
- High: $700 to $1,600. Clone movement, correct thickness, hand-finished bracelet.
Prices shift with the seller and the exchange rate. No copy sells at genuine retail. Any listing that claims a real 15510ST for under $2,000 is a copy.
Checks Before You Buy
- Ask for caliper photos on the case side. Look for 10.4 mm to 10.8 mm.
- Ask for a timegrapher photo. Rate, amplitude, and beat error show movement health.
- Ask for a video of the rotor spinning and the date flipping.
- Ask for a weight photo in grams.
- Read the return policy and the payment method. A chargeback right beats a wire transfer.
