What a fake Rotonde tourbillon is

A fake Rotonde tourbillon is a counterfeit watch. It copies the look of the Cartier Rotonde de Cartier tourbillon. Cartier does not make it. The movement inside is not a Cartier calibre. The case, dial, and hands use lower-grade materials. In the United States, selling counterfeit watches is a federal crime. Buying one for personal use can lead to seizure by U.S. Customs and Border Protection.

Movement tells

The tourbillon is the main test. A real Cartier Rotonde tourbillon has a Swiss manual-wind movement. The cage rotates once per minute. The finishing includes Geneva stripes, polished screws, and engraved bridges. Fake versions often use a Chinese movement. Some fakes have a real tourbillon. Others have a balance wheel with a fake cage that does not rotate. A fake cage often spins with the oscillating weight or not at all. Look at the beat rate. A real tourbillon runs at 21,600 or 28,800 vibrations per hour. Many fakes run at 21,600 but lack the cage. Check the engraving on the bridge. Fakes use shallow laser marks. Real Cartier engraving is deep and crisp.

Case and dial tells

Genuine Rotonde de Cartier tourbillon cases come in platinum, white gold, or rose gold. Case diameters range from 39 mm to 45 mm. The sapphire crystal has an anti-reflective coating. Fake cases often use stainless steel with gold plating. The plating wears off at the lugs and crown. The crown has a blue sapphire cabochon. Fakes use glass or plastic. The dial printing on a real Cartier is sharp. Fake dials have thick ink and uneven Roman numerals. The Cartier secret signature at 7 o'clock is missing or wrong on many fakes. The caseback engraving on a fake has wrong reference numbers and serial numbers.

Price gap

A genuine Cartier Rotonde de Cartier tourbillon costs $100,000 or more at retail. Auction prices range from $50,000 to $200,000 based on reference and condition. Fake Rotonde tourbillons sell for $200 to $800. A real Swiss tourbillon movement alone costs more than $3,000. A fake at $300 cannot contain a real Cartier movement. If the price is under $1,000, the watch is a counterfeit.
