Short answer: 1701 is not a Cartier reference number. Cartier never stamped 1701 on an Astrotourbillon, and you will not find it in any catalog. It is a seller or factory code used inside the replica trade, and it usually maps to one of the Calibre de Cartier or Rotonde Astrotourbillon styles. So before you compare photos or prices, ask the seller which genuine reference the code points to. If the answer is vague, the watch behind the code is vague too.

Start with the genuine watch
The Astrotourbillon arrived in 2010 inside the Calibre de Cartier line, running the in-house calibre 9451 MC. It is a manual-wind movement with roughly 48 hours of reserve in a 47mm case. What makes it special is not the cage itself but where the cage sits. The balance and escapement ride on a rotating arm that sweeps around the center of the dial, one full turn per minute, so the tourbillon doubles as the running seconds. Later skeleton versions used calibre 9461 MC with the same idea and far more open architecture. Genuine pieces sit well into six figures, which tells you most of what you need to know about finishing on a copy.

Why this model is hard to copy well
Most replica complications are cosmetic. This one cannot be, because the whole point is motion you can watch. A convincing copy needs a carriage that orbits the dial center, carries a working balance wheel and escapement, and completes exactly one revolution per minute in step with the seconds track. That is a genuine engineering problem, not a printing problem.
Knockoff Cartier Astrotourbillon 1701: What You Actually Get
Three things show up again and again in cheap versions. The carriage is fixed and just looks like an open-heart cutout. The balance sits outside the arm instead of inside it. Or the arm rotates at the wrong speed, which looks fine in a still photo and wrong on the wrist within ten seconds.
What I check before paying
- Ask for a video, not photos. The seconds hand and the orbiting carriage should be in the same frame for at least 60 seconds.
- Time the revolution. One full lap equals one minute. Anything much faster or slower is a decorative disc.
- Look for the balance inside the cage. If the balance wheel is parked outside the rotating arm, you are looking at a fake tourbillon.
- Check case thickness. The genuine watch is roughly 14.5mm. Copies often add a millimeter or two to fit a donor movement, and that changes the profile.
- Read the dial print at macro. Thin, crisp text with even spacing is a good sign. Fat, smeared print is not.
- Inspect the crown. Blue synthetic spinel cabochon, flush set, no glue line.
- Ask which movement is inside. A real Chinese tourbillon ebauche costs real money. A decorated automatic with a fake bridge does not.
Price tiers, honestly
Under about $400 you are almost certainly buying an open-heart automatic with a spinning ornament. Between roughly $600 and $1,500 you start seeing actual tourbillon movements from Chinese makers, and quality varies a lot. Above that, you are paying for finishing, not for a different mechanism, so ask what specifically improved. No copy at any price matches the hand finishing on a genuine 9451 MC, and any seller who claims otherwise is selling confidence, not a watch.
The part people skip
Counterfeit watches are illegal to import and sell in the US and many other countries, and customs does seize parcels. You have no warranty, no service path, and no resale value. Buy it as a novelty if you buy it at all, never as an investment, and never as something you plan to pass off as genuine. If you want the look without the risk, a legitimate open-heart dress watch from a mid-tier brand gets you most of the visual effect with a real service network behind it.
