The real Patek Philippe 6002G Sky Moon Tourbillon is a double-faced grand complication. Minute repeater with cathedral gongs, tourbillon, perpetual calendar on one side, a rotating sky chart on the other, all sitting in a hand-engraved white gold case. Production is tiny and auction prices run into seven figures. A "fake 6002G" is the other end of that, and the phrase covers a wide spread of objects. If you are shopping, the useful question is not real or fake. It is which tier you are looking at, and what that tier can and cannot do.
The three tiers you will run into
Novelty tier
Quartz movement, printed dial, case cut from plated brass or stamped steel with an engraving pattern rolled onto the surface. These sell for $40 to $150 and they look wrong from arm's length. The 6002G's identity lives in the hand engraving, and stamped patterns read flat and shallow. Hold one under a lamp and the scrollwork has no depth, no undercut, no variation.
Mid tier
Automatic movement, sapphire crystal, decent weight, maybe $300 to $800. Often a single-face watch with a decorative caseback that just copies the front. Moonphase and calendar subdials on these are usually a day and date module with different printing. The sky chart is a flat printed disc, not a rotating celestial plate.
1:1 tier
Closest to the genuine dimensions and heft, with a decorated movement, better engraving and a two-sided layout that at least follows the original. This is where most buyers in this niche end up. It is also where the price gap between a good build and a great one gets wide, and that gap shows up in the small things: dial print sharpness, the finish on the repeater slide, how the hands sit against the chapter ring.
What no replica can do
None of them can be serviced by Patek Philippe. None come with a genuine certificate, and none will hold value. The sound of a real cathedral gong repeater is a function of hardened steel, hand tuning and a case built around the acoustics, and no factory copy reproduces it. Resale is effectively zero. And presenting a copy as the genuine article is trademark counterfeiting, not a gray area, in US law.
Details I would check first
- Engraving depth and consistency around the lugs and bezel edge
- Dial print under a loupe, especially the sky chart markers
- Weight in hand and how the caseback sits flush
- Whether the second dial is functional or decorative
- Movement finishing visible through the display back
- How the repeater slide feels when pushed, if it moves at all
The money reality
Buy a 6002G copy as a wearable piece you enjoy, at a price you can lose. Do not buy one as an investment, do not buy one expecting service, and do not try to pass it off. US Customs seizes counterfeit watches, and the FTC treats selling a copy as genuine as deceptive trade. Know the tier, know the limits, and the purchase makes sense.
