Replica Cartier gold: short answer
In the replica trade, "Cartier gold" is a color, not a metal. Most pieces are stainless steel with a gold coating between 0.5 and 5 microns thick. Solid 18k gold replicas exist but are rare, and the gold content sets a floor on the price.

What the gold layer is
- Gold plating: a thin electroplated layer, 0.5 to 3 microns on most replicas, 5 microns on top-tier claims.
- PVD coating: titanium nitride or a gold alloy deposited in a vacuum. Harder than plating. One fixed shade.
- Gold-tone steel: a color match to 18k yellow gold with no gold content.
Plating wears at the caseback edge, lugs, crown, and bracelet links. A 1 micron layer on a bracelet shows wear in months of daily use. Thicker layers last longer.

Weight and density
Gold has a density of 19.3 g/cm3. Steel is 7.9 g/cm3. A solid 18k gold case weighs about 1.5 to 1.7 times a steel case of the same dimensions. Plated replicas match the look, not the mass. A Cartier Tank or Santos replica in gold tone sits near the weight of the steel original.
Marks and hallmarks
Authentic 18k Cartier cases carry a "750" stamp, a maker's mark, and a French assay mark (eagle head) on older pieces. Swiss pieces carry a St. Bernard dog head or a balance scale. Replica stamps copy the digits, not the metal. An XRF test reads the alloy in seconds and shows steel under the plating.
Legal status in the US
Trafficking in counterfeit goods is a federal offense under 18 U.S.C. § 2320. A first offense carries up to 10 years. CBP seizes counterfeit watches at ports and can destroy shipments. The buyer carries the loss. Cartier does not service, authenticate, or supply parts for replicas.
Points to check before buying
- Ask for plating thickness in microns. A seller with no number has no answer.
- Ask for case weight in grams. Compare with a published steel spec.
- Ask for an XRF reading or a photo of the caseback stamp.
- Check the return terms. Seizure at customs is a common outcome.
