Short answer

Cartier does not use the number 410216. Cartier references start with a W. A steel Clé de Cartier with a 35 mm case is sold as WSCL0007. The string 410216 comes from reseller stock sheets, auction lots, or listing templates. A seller who posts "Clé de Cartier 410216" is using a house number, not a factory number.

The Clé de Cartier line

Cartier launched the Clé de Cartier in 2015. The crown is shaped like a key, which gives the model its name. Case sizes are 31 mm, 35 mm, and 40 mm. Cases come in steel, 18k pink gold, 18k white gold, and platinum. Early models used the caliber 1847 MC automatic movement. Dials are silvered opaline, white, or blue. The case back is curved and the key-shaped crown holds a synthetic spinel cabochon.

What a replica listing claims

Listings in this category use terms such as 1:1, Swiss movement, ETA clone, and AAA grade. None of these terms has a published standard. No trade body certifies them. A buyer cannot confirm movement origin, case alloy, or water resistance from listing text alone.

Legal status in the United States

Counterfeit watches are illegal to sell or import in the US. The Lanham Act, 15 U.S.C. § 1114, covers trademark infringement. Under 19 U.S.C. § 1526, US Customs and Border Protection can seize and destroy counterfeit goods at import. CBP publishes seizure figures for counterfeit watches and jewelry each year. A personal-use purchase is not a defense for the seller. Sellers face civil damages and criminal charges under 18 U.S.C. § 2320.

What is not known
