A fake Cartier Astrotourbillon 42mm is a replica of Cartier's tourbillon wristwatch, and the name covers many different builds rather than one product from one factory. Two watches sold under the same label can differ in movement, case finishing, dial detail, and strap quality, so the wrist feel changes a lot from one seller to the next. The single most important question is whether the tourbillon carriage is a real rotating cage or a decorative imitation.

What the Astrotourbillon Design Copies
Cartier's Astrotourbillon is recognized for a tourbillon carriage that sits near the center of the dial and carries a long seconds hand around the track. Replicas aim at those visual cues: the open, airy dial, the rotating cage, Roman numerals, a fluted crown with a blue cabochon, and a 42mm case with slim lugs.
The genuine watch uses an in-house Cartier manufacture caliber with hand finishing that no replica reproduces. Cartier owns the Astrotourbillon name and the design rights behind it, so a replica is a copy of the look, not a product from the brand.

Quality Tiers You Will See
- Entry tier. Usually a plated or painted case, mineral glass, stamped dial, and a basic automatic movement. The tourbillon is almost always decorative.
- Mid tier. Solid stainless steel case, sapphire crystal, better dial printing, and a cleaner caseback. Some models use a real tourbillon cage at a higher cost.
- Upper tier. Closer case proportions, brushed and polished surfaces that meet at defined edges, applied indices, and a genuine tourbillon escapement with visible cage rotation.
How to Judge a Fake Cartier Astrotourbillon 42mm
Movement and carriage
Ask for a video, not a still photo. A real tourbillon cage completes a full rotation once per minute and the balance wheel sits inside the cage. A decorative version often shows a rotating disc, an open-heart cutout, or a balance wheel that stays fixed while a separate hand sweeps.

Case and crystal
Check lug shape, crown size, and whether the crystal sits flush. Sapphire should stay clear at an angle; mineral glass shows a slight haze and scratches early.
Dial, hands, and printing
Look at the spacing of the Roman numerals, the finish on the hands, and whether the dial text is sharp under magnification. Blurry or thick printing is a common sign of a lower tier build.
Caseback and engravings
Engraving depth and reference numbers should be crisp. Buyers should also remember that a replica is never a genuine Cartier product and should not be sold or passed off as one.
Strap and clasp
Alligator-grain leather should have a soft, uneven texture rather than a repeating printed pattern. Check stitching density and whether the buckle finish matches the case.
Real Tourbillon vs Decorative Tourbillon
A working tourbillon adds real mechanical complexity and cost. If a listing shows a low price and claims a tourbillon, the mechanism is likely a decorative module. If the price is higher, ask for proof of the escapement and a clear view of the cage in motion.
Legal Points to Keep in Mind
Counterfeit trademarked goods are illegal to import and sell in the United States. Trademark law protects the brand name and logo, and sellers of replicas carry real legal risk. Buyers should treat these watches as decorative copies for personal wear only, never as investments and never as genuine goods.
Questions to Ask Before You Buy
- Is the tourbillon genuine or decorative?
- Can you send a video of the carriage rotating?
- What is the case material, and is it solid or plated?
- Is the crystal sapphire or mineral glass?
- What is the return policy if the watch arrives damaged?
Bottom Line
A fake Cartier Astrotourbillon 42mm is worth buying only when the seller is honest about the movement, the materials, and the fact that it is a replica. Focus on the tourbillon type, the case finish, and the crystal first, because those three details separate a wearable copy from a disposable one.
