The short answer: there is no fake Patek Philippe 6002G worth buying. The 6002 is the Sky Moon Tourbillon, a grand complication built around a minute repeater, a tourbillon and a celestial display, produced in a precious metal case in tiny numbers and priced in the millions of dollars. That distance between the real watch and its copies is the whole market. Any watch sold as a 6002G is judged here on four criteria: movement fidelity, case and dial finishing, whether the complications actually function, and the legal and ownership exposure that comes with the watch.

The real 6002G, and what a copy has to match

The Sky Moon Tourbillon is a two-sided watch. The front dial reads mean solar time, and the reverse side is built around a celestial display that tracks the night sky and the moon. Inside sits a hand-wound movement combining a minute repeater with a tourbillon, and the chime comes from tuned gongs struck by hammers, with the case acting as the soundboard. Matching that in a copy means matching a movement, a sound, a precious metal case with correct hallmarks, and hand finishing on every visible bridge. No copy does all four.

Tier one: the cheap 6002G from marketplaces and night markets

These are the listings that show up for a few dozen dollars, usually photographed better than they are built. The case is plated base metal, the movement is quartz, and the celestial side is a printed disc or a sticker under glass.

Pros

  • Costs less than a strap for a real watch.
  • Needs no servicing, because it is disposable.
  • At arm's length in a low-resolution photo, the dial layout is roughly right.

Cons

  • The seconds hand ticks instead of sweeping, which is the first thing any watch person checks.
  • The repeater slide is molded plastic or a push piece connected to nothing.
  • Case diameter, thickness and crown position are wrong, so it wears like a novelty.
  • Engraving, hallmarks and font weight fall apart next to a catalog photo.

Who it suits: nobody who wants a watch. If you need a prop for a staged photo, a plain no-logo dress watch reaches the same result without carrying someone else's trademark.

Tier two: the automatic copy sold as the closer fake

This is the middle of the market, a few hundred dollars, and it is where most buyers searching for this term end up. The watch runs on a generic Chinese automatic movement with a decorated rotor, the dial printing is sharper, and the strap is wearable.

Pros

  • A mechanical movement that keeps time on a desk, which feels more credible than quartz.
  • Applied markers and better dial printing that hold up in daylight photos.
  • Case polishing that mimics a luxury finish from three feet away.

Cons

  • The complications are decorative. Subdials are driven by whatever gear train happens to fit, not by a celestial or repeater mechanism.
  • Case thickness runs a millimeter or more off, which changes how the watch sits under a cuff.
  • Under a loupe, the finishing, engraving and caseback markings are the giveaway.
  • Watchmakers with a parts account will not service a counterfeit movement, and spare parts do not exist.

Who it suits: a buyer who wants a dress watch that starts conversations at a distance. It fails the moment someone who owns a real grand complication handles it.

Tier three: the high-end copy

The top tier of the counterfeit market, where sellers ask a four-figure sum and ship in a replicated box with replicated paperwork. Case density is sometimes increased to imitate the heft of gold, and the dial fonts are traced from the real thing.

Pros

  • Better case and dial finishing than the tiers below it.
  • Weight and wrist presence that land closer to the real reference.
  • Packaging detailed enough to fool a non-specialist at a glance.

Cons

  • The price crosses into the range of a genuine entry-level luxury watch, which is money you could spend on something with a warranty.
  • There is still no minute repeater and no tourbillon. The back of the watch is a display, not a mechanism.
  • Legal exposure is highest here, because these are the orders that ship across borders in volume.
  • No authentication, no service network, and no resale channel.

Who it suits: nobody who treats a watch as an asset. At this price the honest comparison is a genuine dress watch from an established brand.

Legal and ownership reality

  • Importing counterfeit goods into the United States is illegal, and shipments are subject to seizure and destruction.
  • Offering one for sale as a genuine Patek Philippe is trademark counterfeiting and fraud, not a gray-market technicality.
  • No brand service center will touch it, and independent watchmakers often refuse to open counterfeit cases.
  • Insurers and auction houses reject them, so there is no exit when you want your money back.

There is no pro list for this section. The risk is not theoretical and it does not shrink because the watch cost more.

What to buy instead, by use case

  • You want the complication: a legitimate moonphase dress watch from an established brand gives you a working complication, real service, and resale value.
  • You want the name: a pre-owned entry Patek reference fits a realistic budget and holds value, even if it is not a grand complication.
  • You want the look for one night: a plain dress watch on a good leather strap does that job, and nobody inspects the caseback at a party.

The 6002G is one of the most complicated watches in production, and a copy delivers the silhouette with nothing underneath it. For a buyer comparing tiers, that is the entire review.
