Short answer
A fake automatic Cartier watch is a replica with a mechanical self-winding movement. A weight called a rotor spins when the wrist moves. The rotor winds the mainspring. The mainspring drives the hands. Cheap Cartier replicas use quartz instead. A quartz watch ticks once per second. Most automatic movements run at 28,800 vibrations per hour, which equals 4 Hz. The second hand moves in eight small steps per second at that rate.
Movements found in fake automatics
Copy factories do not build their own calibers. They buy third-party movements and print Cartier text on the rotor.

- Seagull ST2130: 28,800 vph, 38 to 42 hours of power reserve, a copy of the ETA 2824-2.
- Miyota 9015: 28,800 vph, 42 hours of power reserve, made in Japan, common in mid-range copies.
- Hangzhou 6300 and similar calibers: 28,800 vph, rougher finish on bridges and rotor.
- ETA 2824-2 or Sellita SW200: Swiss calibers, found in the highest-priced copies.
Cartier fits its own calibers to genuine watches. The 1847 MC movement entered production in 2015. Genuine Cartier automatics carry the Cartier name, a caliber number, and a serial on the movement and the caseback.
Checks that need no tools
- Watch the second hand for 60 seconds. A smooth glide points to mechanical. One jump per second points to quartz.
- Turn the crown 30 turns. A mechanical watch builds power in a mainspring. A quartz watch has no mainspring.
- Set the watch down for 40 hours. A wound automatic still runs. A quartz watch runs for years on one battery.
- Look at the rotor through the display back. Genuine Cartier rotors carry engraved text, Cotes de Geneve stripes, and a rhodium or gold finish.
- Weigh the watch. A steel Cartier Santos medium with bracelet sits near 100 grams. Many copies land under 90 grams.
Checks that need the caseback opened
A watchmaker looks at the movement holder, the jewel count, the shock protection, and the depth of the engraving. A genuine 1847 MC has 23 jewels and a 42-hour power reserve. Seagull and Miyota calibers have different bridge shapes. Bridge shape is the fastest tell, because printed text can be copied and cast metal cannot be reshaped without new tooling.
Serial numbers and papers
Cartier puts the serial on the caseback. The serial matches the warranty card and the boutique record. Copy serials repeat across batches, so two copies from one seller can share a number. Cartier will not service a watch with a serial that does not match its records.
Price ranges
- Quartz fake Cartier: 30 to 80 USD.
- Automatic fake with Seagull or Miyota: 150 to 400 USD.
- Automatic fake with Swiss ETA or Sellita: 500 to 1,200 USD.
- Genuine Cartier Santos medium in steel: near 7,000 USD at retail.
A single genuine Cartier automatic movement costs more than most complete copies. That price gap sets the ceiling on copy quality.
Open questions
No public data exists on the number of fake Cartier automatics sold each year. Cartier does not publish seizure figures, and customs agencies report totals for all counterfeit goods rather than by brand.
