A fake Cartier two tone watch is a counterfeit copy of a steel and 18k gold Cartier model, most often the Santos, Panthère, or Tank Française. The fastest way to spot one is the gold: real Cartier two tone pieces use solid 18k gold for the bezel, links, and crown, while fakes use gold plating that thins at the clasp and case edges within months.
What does two tone mean on a Cartier watch?
Two tone means a watch built from two metals: stainless steel plus 18k gold. Cartier stamps the gold parts with a 750 mark, and that mark refers to gold content, not plating thickness.
- Santos de Cartier: steel case and bracelet with a gold bezel, gold screw heads, and gold center links.
- Panthère de Cartier: a gold and steel link bracelet where the gold links repeat in a fixed pattern.
- Tank Française: steel body with gold case edges and gold bracelet center links.
- Ballon Bleu de Cartier: steel case with a gold bezel and gold crown guard on two tone references.
How do you spot a fake Cartier two tone watch?
Six details separate a counterfeit from a real piece, and all of them are visible without opening the case.
1. The gold is plated, not solid
Look at the clasp, the crown, and the outer edges of the links. Plating rubs off where skin meets metal, so a fake shows gray steel under a yellow or pink surface. A scratch on a real gold link shows gold all the way down, because the metal is solid.
2. Hallmarks and engraving depth
Cartier stamps 750 or Au750 on gold components, along with a maker's mark and Swiss assay marks on older pieces. Fake stamps sit shallow, off-center, or in a font that runs crooked against the caseback. Run a fingernail across the engraving: real stamps cut into the metal, fakes rest on the surface.
3. Dial printing and the hidden signature
Cartier prints dials with thin, crisp strokes, and the Roman numerals follow a fixed shape, including the slanted VII. Several models hide a tiny CARTIER word inside one numeral, and on fakes that word is absent, blurred, or the wrong size. Check the Swiss Made line at 6 o'clock, since letters that crowd the minute track or stop short point to a copy.
4. The crown cabochon
Cartier sets a blue synthetic spinel in the crown of most two tone pieces. The stone sits flush, holds a deep even blue, and has a polished domed top. Fakes use glass, plastic, or dyed resin that turns milky under light or sits proud of the crown.
5. Bracelet links and screws
Santos bracelets use Cartier's SmartLink system, where each link releases with a push pin. Fake bracelets use split pins, mismatched screw heads, and links that wobble at the hinge. On the Panthère, the gold and steel links alternate in an exact pattern, not an approximate one.
6. Movement and caseback stamps
The Tank Must runs on quartz and the Santos runs on the automatic 1847 MC, so a two tone Santos with a hand that jumps once per second is a fake. Casebacks carry the model name, reference number, and serial in a set order. Missing numbers, or the same serial across many listings, is a red flag.
Which two tone Cartier models get copied most?
The Santos and Panthère top the list because their shapes and link patterns are easy to machine. Tank Française copies follow, then the Ballon Bleu two tone. New references get copied within months, so a recent launch is no protection.
What do fake Cartier two tone watches sell for?
Replica listings for two tone Cartier pieces run from about $50 to a few hundred dollars, and the price tracks plating thickness and the movement inside. A real two tone Cartier costs several thousand dollars more than its all-steel sibling, because the gold is solid and priced by weight. A seller offering an 18k two tone Santos for under $500 is selling plating.
Do gold plated replicas hold up over time?
Plating wears at the highest-contact points first: the clasp, the crown, and the link edges near the wrist. Most gold plated bracelets show silver by 6 to 18 months of daily wear, and re-plating a two tone bracelet costs more than the watch itself. That contrast between gold and bare steel is what gives a worn fake away at arm's length.
Which checks settle the question fastest?
- Inspect the gold: hallmarks and plating wear decide most cases.
- Read the dial under a loupe: printing, hidden signature, and Swiss Made placement.
- Open the caseback: movement type and serial stamps.
Frequently asked questions
Does Cartier make any gold plated watches?
No. Cartier uses 18k gold or stainless steel, and the company does not plate its cases or bracelets. A listing that describes a gold plated Cartier is describing a counterfeit.
Are two tone Cartier watches solid gold?
Only the gold components are solid gold. The case body, caseback, and outer links are stainless steel on a two tone reference. That is why a two tone watch weighs less than an all-gold version of the same model.
Where is the serial number on a Cartier two tone watch?
On the caseback, engraved at the edge, next to the reference number and model name. Some references also print the serial on a lug or on the bracelet clasp. Fakes often skip the serial or repeat one number across many units.
Can a jeweler confirm a fake in person?
Yes. A jeweler checks hallmark depth, tests the gold with acid or a scanner, and opens the caseback to see the movement. Gold testing takes about a minute and settles the plating question.
How heavy should a two tone Cartier feel?
Heavy enough that the bracelet feels dense in the hand and the head sits solid on the wrist. Fakes run light because plated brass and hollow links replace steel and gold. Weight alone is not proof, but a Santos that feels hollow at the clasp deserves a closer look at the stamps.
