A comprehensive guide from production source to identification technology · The latest blockchain anti-counterfeiting application

Evolution of counterfeit technology in 2021
According to the monitoring of the International Anti-Counterfeiting Alliance, Cartier fake have developed three major technical schools:
- Digital clone: 3D laser scanning of genuine modeling, error ≤0.03mm
- Swiss hybrid version: ETA movement + domestic shell combination, can only be identified when the cover is opened in the counter
- NFT counterfeits: a new scam of forged digital certificates combined with physical goods
The latest seized cases show that high-end Cartier can pass the counter:
- Spectrum detection (metal composition matching)
- Macro camera inspection (surface process simulation)
- Weight test (error controlled within ±0.5g)

Comparison table of core identification points
Identification dimensions | Authentic features | fake Cartier Flaws |
---|---|---|
Sapphire crown | 57 facets, refractive index 1.762-1.770 | Synthetic corundum, refractive index deviation>0.008 |
Screw marks | Thread spacing 0.25mm, 45° chamfer | Thread is rough, 30-50° irregular chamfer is common |
Movement balance wheel | 18K gold weight screw, two-way winding | Gold-plated steel screw, 83% of the winding is one-way |

Anti-counterfeiting technology breakthroughs in 2021
Cartier’s latest Phygital authentication system includes:
- NFC chip: implanted inside the case, reading distance ≤2cm
- Quantum dot tag: requires special UV light to show
- Blockchain evidence: synchronize global nodes every 15 minutes
⚠️ Note: The cloned version of Cartier that appeared after Q4 2021 can already imitate NFC chip data, and needs to be verified with the official website QR code.
