How to Spot a Fake Audemars Piguet Royal Oak

The fastest tell is the bezel screws. On a genuine Royal Oak, all eight hexagonal screws are functional. They thread into the case from the back, and their slots sit at random angles instead of forming a neat ring. Counterfeits use decorative screw heads that are pressed or glued into the bezel, and the slots usually line up in a perfect pattern. Confirm that first, then work through the dial, bracelet, movement, and paperwork.

What to Have on Hand

  • A 10x jeweler's loupe or a phone macro lens
  • Reference photos of the exact reference number, dial color, and caliber
  • The seller's original listing photos at full resolution
  • A watchmaker who is willing to open the caseback

Authentication Checklist

  1. Measure the case diameter and thickness, then compare both numbers with the published spec for that reference. A Royal Oak 16202 is about 8.1 mm thick at 41 mm wide. Copies commonly run 1 to 2 mm thicker.
  2. Look at the bezel screws from the side. Genuine screws sit slightly proud of the bezel, show a machined hex head, and point in different directions.
  3. Ask the seller to photograph the inside of one bezel screw from the caseback side. Real screws show threaded ends that pass through the case.
  4. Study the tapisserie dial under magnification. Grande Tapisserie squares are uniform in size, cut to an even depth, and have sharp edges. Copies show shallow, rounded, or uneven squares.
  5. Read the dial printing. The words Audemars Piguet and Automatic should be crisp with clean edges and no ink bleed at 10x.
  6. Inspect the applied AP monogram at 12 o'clock. It should be solid gold, fully separated from the dial, and mirror polished on every face.
  7. Check the date aperture. The frame is beveled and the date font is thin and centered. Fakes often show a flat cutout and a bold or off-center numeral.
  8. Flex the bracelet and feel the end links. A genuine integrated bracelet has tight tolerances, a smooth taper, and no rattle or sharp edges where it meets the case.
  9. Examine the hands. Bevels, polish, and lume application are even on a genuine piece, with no overflow onto the hand sides.
  10. Turn the watch over. The sapphire caseback should show the correct caliber number, Geneva stripes on the bridges, perlage on the mainplate, and a rotor engraved with the AP crest. Time the balance: genuine automatic Royal Oaks beat at 4 Hz, or 28,800 vibrations per hour.
  11. Compare the engraved reference and serial numbers with the warranty card and any service paperwork. Engraving on a genuine case is crisp and cut into the metal, not laser-etched with a hazy edge.
  12. Check the asking price against current secondary market listings. A steel Royal Oak offered far below that range is not a bargain.
  13. Take the watch to a watchmaker or an authorized service point for an opening and a movement inspection before money changes hands.

Where Copies Fail Most Often

Bezel screw function, tapisserie depth, bracelet end link fit, and movement finishing account for most of the failures. Dial printing and case thickness come next. Gold models add another layer: real cases carry hallmarks and purity stamps that copies rarely reproduce with the right placement or depth.

Before You Buy

Buy from a seller who will provide macro photos, a live video call, and a written return window. In the United States, importing or selling a counterfeit trademarked watch is illegal, and Customs can seize the item, which means a fake usually costs the buyer the full price with no recourse.
