The short answer: no one makes an accurate knockoff of the Cartier Astrotourbillon. The "1701" listings are cosmetic tributes. The real watch runs Calibre 9451 MC, where the tourbillon carriage orbits the dial on a rotating arm instead of sitting in a fixed cage. Nothing in the replica price range reproduces that. What you get is a case and dial that read correctly in photos, plus either a spinning decorative arm or a plain open-heart movement sitting behind a big aperture.
What the 1701 replica actually is
The "1701" tag is a seller catalog code, not a Cartier reference. Cartier references run in formats like W7100002, so treat any 1701 label as a listing number invented by the dealer. That tells you something about the supply chain: these come from generic replica factories working off press photos, not from anyone with access to a real sample.
Expect a case sized close to the genuine Rotonde, roughly 47mm across, but usually thinner because there is no orbital module inside. The dial is printed with Roman numerals and a guilloché-style texture that looks convincing at arm's length and flat under a loupe. Hands are typically polished steel with soft edges. The crown cabochon is almost always glass or synthetic spinel rather than sapphire.

Testing the tourbillon claim
This is the one check that separates a tolerable fake from a waste of money. Ask the seller for a single unedited 60-second video with the watch running.
- The arm should complete exactly one full lap in 60 seconds. Time it. If it drifts, stutters, or snaps back, the arm is decoration driven off a separate wheel train.
- Look for the balance wheel riding at the tip of the arm. On the real watch the regulating organ travels with the arm. Most knockoffs keep the balance fixed and spin a thin plate around it.
- Watch the aperture edges. A genuine orbital tourbillon needs real depth in the case. A shallow, flat opening is a giveaway.
- Check noise. A decorative arm running off a quartz or cheap automatic train often ticks audibly near the ear.
If a seller cannot produce that video, the watch does not do what the listing says.
Movement tiers you will be offered
Quartz versions exist and the arm either sweeps in a fake loop or does not move at all. Above that sits a standard Chinese automatic with a stamped bridge shaped like the Cartier architecture, and it fools nobody who looks twice. The closest honest option is a genuine Chinese tourbillon with a fixed cage behind the aperture. It is a real tourbillon, just not an orbiting one. It costs more, and it is the only version where the mechanics earn any respect.
Finish, caseback, and water resistance
Genuine Cartier haute horlogerie finishing means hand-applied anglage, polished screw heads, and crisp engraving. Knockoffs show stamped bevels, uneven brushing, and laser-etched caseback text that rubs away. Assume no meaningful water resistance no matter what the listing claims; the gaskets on these cases are not tested, and the aperture seals are the first thing to fail.
Price reality
Quartz cosmetic versions sit at the bottom of the market. Automatic versions with a spinning plate run a step higher. Real-tourbillon versions cost several times that and are still not the watch in the photos. Anyone asking four figures for a 1701 is selling you a story, not a movement. Budget for a service you will never get, and check whether the seller will accept a return before you send money.
Legal and practical notes for US buyers
Counterfeit goods carrying a trademark are subject to seizure by US Customs, and reselling them is a separate problem. There is no warranty, no parts support, and no watchmaker who wants the repair. If the look is what you want rather than the name, a real tourbillon from an independent brand gets you the aperture and the motion with a movement you can actually service.
