Short Answer

A fake Audemars Piguet ref 16402 is a replica of a thin Royal Oak reference, built to copy the octagonal bezel, tapisserie dial, and integrated bracelet of the original. Replica quality runs from a cheap quartz lookalike to a so-called super clone that mimics case proportions and movement layout. None of them are genuine Audemars Piguet, and exact specification for any single reference should be confirmed through AP's own records before you rely on it.

What Ref 16402 Refers To

Reference 16402 belongs to the Audemars Piguet Royal Oak line, the family defined by an octagonal bezel with exposed screws, a slim case, and a dial finished in the tapisserie pattern. Royal Oak references have been produced across many years, metals, and dial variants, and details such as case diameter, thickness, and calibre differ between them. That variation is exactly what makes replica identification tricky: a fake can look convincing in isolation and still fail when measured against a documented original.

Why Fakes of This Reference Are Common

  • Demand for Royal Oak watches is high, and supply at retail is limited.
  • Genuine examples change hands for large amounts, which makes a few hundred dollars for a replica tempting.
  • The design is instantly recognizable, so a convincing copy carries social weight for the wearer.
  • Online listings, social media sellers, and small workshops make replicas easy to find.

Replica Tiers You Will See

Most sellers use loose labels. Treat them as quality bands rather than certifications.

  • Budget quartz fakes: light weight, thick case, painted or stamped dial, no attempt at movement decoration.
  • Mid-tier automatic: a generic automatic movement, closer case shape, and a bracelet with rough edges and loose end links.
  • Super clones: copied case dimensions, a decorated movement plate, and a dial with a printed tapisserie pattern instead of a stamped or guilloche surface.
  • Franken builds: a replica case combined with a few genuine or aftermarket parts, often sold as genuine.

How to Spot a Fake Audemars Piguet Ref 16402

These are the areas where replicas usually give themselves away. Bring a loupe, a caliper, and reference photos of a documented original.

  1. Case profile: measure thickness and compare the bezel angle to a real example. Copies often run thicker and softer.
  2. Dial texture: the tapisserie squares on a genuine dial have crisp, consistent geometry under magnification. Printed replicas look flat and slightly blurry at the edges.
  3. Printing and date window: check font weight, spacing, and alignment. A date aperture that sits slightly off center or a date wheel that is not color matched is a strong warning sign.
  4. Hands and polishing: genuine hands have sharp bevels and clean finishing. Replica hands look brushed flat or show tool marks.
  5. Bracelet and clasp: the taper should be gradual, links should move without rattle, and clasp engraving should be deep and even.
  6. Caseback and movement: engraving depth, rotor finishing, and jewel count are common failure points on fakes.

Movement and Weight

A genuine thin Royal Oak carries a slim, high-grade automatic calibre, and that shows up in how the watch sits on the wrist and how the rotor behaves. Replicas either use a thin quartz movement that removes the sweep of the seconds hand or a modified automatic that adds height to the case. Weight alone is not proof, since tungsten inserts can compensate, but combined weight, thickness, and hand sweep together are hard to fake.

Price Context and Legal Risk

Even the best replica costs a fraction of a genuine example, and that gap is the clearest signal in any listing. Buying or importing counterfeit watches is illegal in many countries, including the United States, where customs authorities seize counterfeit goods and rights holders can pursue sellers. Selling a replica as genuine is fraud. If you are shopping the secondary market, insist on service records, an independent authentication, and a seller who accepts returns.

Before You Buy: Quick Checklist

  • Ask for high-resolution photos of the caseback, dial, and clasp.
  • Compare measurements against published reference data.
  • Request a movement photo and confirm the calibre number.
  • Check whether the price matches a genuine example or a replica.
  • Use a third-party authenticator for anything above your comfort threshold.
