What Is the Cartier Astrotourbillon 1701?
The Cartier Astrotourbillon is a real watch: a Rotonde de Cartier model whose tourbillon carriage sits at the center of the dial and turns once a minute. The number 1701 is not a Cartier reference for it, and Cartier has never sold an Astrotourbillon under that code. The phrase appears in replica listings as a batch or factory tag, so a watch sold as a replica Cartier Astrotourbillon 1701 is a counterfeit with an invented model name.
Cartier introduced the Astrotourbillon in 2010 to show off its in-house movement work. Collectors know it for the floating cage that sweeps the dial like a seconds hand. Nothing about the name 1701 comes from Cartier's catalog.
How the Real Astrotourbillon Works
The watch is built around Cartier caliber 9451 MC, a hand-wound in-house movement. Instead of hiding the tourbillon at 6 o'clock, Cartier placed the carriage at the center, and the cage carries a long arrow hand that marks the seconds.
- Tourbillon carriage at the dial center, one full turn per minute.
- Hand-wound in-house movement, visible through a sapphire caseback.
- Large round case, offered in palladium, rose gold and white gold in early runs.
- A carbon crystal version followed in 2013, made in a run of 50 pieces.
- Hand-finished bridges with Cotes de Geneve stripes, blued screws and bevelled edges.
That central layout is the hard part to copy. A standard tourbillon sits in one spot and spins. Cartier's version rotates around the middle of the movement while driving a seconds hand.
Why 1701 Shows Up in Replica Listings
Replica sellers tag watches with short codes that mean nothing outside their own supply chain. Codes track the factory, the batch, or the version number of a given fake. 1701 fits that pattern.
Cartier reference numbers look different. They start with letters and run longer, such as the W-prefixed codes on modern Rotonde models, and they appear on the caseback next to a serial. Older Cartier watches do carry short case numbers, which sellers borrow to make a fake sound official.
If a listing pairs 1701 with a Swiss made claim and a wholesale price, treat both claims as marketing. Real Astrotourbillon production is small, and the watches trade in the six-figure range.
How to Spot a Fake Astrotourbillon
Check the movement first. Photos of the caseback tell you more than any dial shot.
- Watch the cage for 60 seconds. A real Astrotourbillon completes one turn in one minute and the arrow hand tracks true seconds.
- Study the finishing. Look for striped bridges, polished bevels, blued screws and circular graining on the mainplate. Flat painted surfaces mean a fake.
- Time the balance. Cheap cages wobble, stall, or run at the wrong rate.
- Inspect the crystal. Cartier uses sapphire with an anti-reflective coating. Mineral glass shows haze and scratches.
- Read the caseback. Shallow laser-etched text with mismatched numbers is a warning sign. Genuine engraving is crisp and the serial matches the paperwork.
- Weigh the watch. Gold and palladium cases feel dense. Steel fakes feel light for their size.
- Ask for papers. Box, warranty card and service records should line up with the case numbers.
What Swiss Made Replica Claims Really Mean
Swiss made is a protected label with legal rules about where a movement is built and finished. Counterfeit watches rarely meet those rules, and many replica Astrotourbillons run on Asian-made movements that sellers describe as Swiss. The label on a fake is a sales line, not a certificate.
Replica makers also reuse stock photos of genuine watches in their listings. The watch that ships can differ from the photos in case thickness, dial color and strap hardware. Few buyers get to compare the two side by side before paying.
Prices, Authenticity Checks and Legal Risk
A genuine Astrotourbillon sells for six figures in USD on the secondary market, and a Cartier boutique or authorized service center can confirm a watch. A replica price of a few hundred dollars is the clearest signal that you are looking at a counterfeit.
US Customs and Border Protection can seize counterfeit watches at the border, and trademark owners can file civil claims against sellers. Counterfeit watches also skip quality control, so water resistance, materials and movement reliability are guesses.
FAQ
Does Cartier make a model called the Astrotourbillon 1701?
No. Cartier makes the Rotonde de Cartier Astrotourbillon. The 1701 tag belongs to replica trade shorthand, not to Cartier's catalog or archives.
Do replica Astrotourbillons contain a real tourbillon?
Some fakes use mass-produced tourbillon movements from Asian factories. None copy Cartier's central carriage, its one-minute rotation linked to a seconds hand, or the hand finishing of caliber 9451 MC.
How much does a genuine Astrotourbillon cost?
Expect six figures in USD. Prices vary with metal, edition and condition, and the carbon crystal version carries a premium because only 50 were made.
How can I authenticate a Cartier watch?
Take it to a Cartier boutique or authorized service center. They can open the case, check the movement and match the serial to Cartier's records.
Is buying a replica watch illegal?
Importing counterfeit goods into the US is illegal, and CBP can seize the shipment. Selling counterfeits exposes a seller to civil suits from the trademark owner.
