Answer
"410200" is not a Cartier reference number. Cartier uses alphanumeric references for the Clé de Cartier line, such as WSCL0016 or WGCL0004. The six-digit string 410200 appears in replica catalogs, marketplace listings, and search indexes. It points to a counterfeit watch, not a genuine one. Cartier has never published a reference in that format.
What the genuine Clé de Cartier is
Cartier introduced the Clé de Cartier in 2015. The name comes from the crown, which is shaped like a key. Cases came in 35 mm and 40 mm. Most steel versions used the in-house caliber 1847 MC, an automatic movement with 23 jewels and a 42-hour power reserve. The line no longer appears in current Cartier catalogs.
Why sellers use codes like 410200
Replica factories assign internal codes to batches. A six-digit code tracks case size, dial color, and movement grade without naming the brand. Buyers then search the code and land on listings. The same watch can appear under several codes.
Points that separate real from replica
- Reference format. Genuine Cartier references start with letters. A six-digit number alone is not a Cartier reference.
- Movement. Genuine 35 mm and 40 mm Clé models used the 1847 MC. Replicas use generic or cloned movements, and the rotor often carries no Cartier engraving.
- Crown. The genuine key-shaped crown holds a sapphire or spinel cabochon set in metal. Replicas use glass or plastic, and the key profile is off.
- Caseback. Genuine engraving is deep and includes the reference, serial, case metal, and Swiss made. Replica engraving is shallow, and the serial repeats across units.
- Weight. Put the watch on a scale. A reading that differs by more than 5 g from a documented genuine weight is a warning sign.
Legal status in the United States
18 U.S.C. Section 2320 makes trafficking in counterfeit goods a federal crime. A first offense by an individual carries up to 10 years in prison and a $2 million fine. U.S. Customs and Border Protection seizes counterfeit watches at ports of entry. A seized parcel means the buyer loses both the watch and the money paid.
Unknowns
No public record shows which factory uses the code 410200. Cartier does not comment on replica codes. Prices listed under this code vary by seller and cannot be verified.
