A fake Cartier Tank Anglaise gives itself away in three places: the recessed crown, the bracelet end links, and the dial printing. Genuine examples have a crown set into a curved cutout in the case flank, end links that meet the case with no gap, and crisp guilloche engraving under the Roman numerals. Most copies miss at least one of the three, including the expensive ones sold as 1:1.
What is the Cartier Tank Anglaise?
The Tank Anglaise is a Tank variant Cartier introduced in 2012 with an integrated bracelet and a crown partly sunk into the case side. It came in small, medium, and large sizes, in steel and gold, with quartz or automatic movements depending on size. Cartier phased the line out by the end of the 2010s, which is why nearly every Tank Anglaise on the market today is pre-owned.
How do you spot a fake Cartier Tank Anglaise?
1. Check the crown and its cutout
On a genuine watch the crown nests inside a machined notch in the case, so the cabochon sits almost flush with the flank. Fakes usually mount the crown on a standard tube, leaving it standing proud of the case. Run a fingernail along the side: the real transition is a smooth machined curve, not a bump.
2. Weigh it and measure the profile
Counterfeit cases are often cast rather than milled, so they feel lighter than solid steel should and look thick from the side. Genuine cases have a flat, sharp bezel edge and even polish. If the watch feels hollow or the lugs flex, stop there.
3. Study the dial printing and guilloche
Cartier prints the logo and numerals with a clean, slightly raised coat of paint; copies show fuzzy edges, uneven strokes, and Roman numerals that sit off-center in their track. The guilloche lines should be cut into the dial and catch light at an angle, not printed flat. Some Cartier dials hide the brand name inside a numeral, and a decal version of that detail always looks pasted on.
4. Inspect the bracelet and clasp
Each link should alternate brushed and polished surfaces and move without rattle. Copies typically show soft edges, mismatched finishes, and a clasp stamp that is laser-etched instead of deeply engraved. Check where the bracelet meets the case: a gap or a wobble there is a strong fake tell.
5. Verify the caseback and serial number
Reference and serial numbers on authentic watches are engraved deep and uniform, with correct spacing and no typos in "Swiss Made" or the water-resistance marking. Photograph the caseback and ask Cartier or an authorized service center to confirm the number before you pay. Fakes often reuse one serial across many units, which is easy to catch.
6. Look at the crystal and movement
Genuine watches use sapphire crystal with an anti-reflective coating, so the dial stays legible at sharp angles. Under the caseback, an automatic Cartier movement shows Geneva stripes, blued screws, and signed rotor engraving; quartz copies hide a generic module under a plain plate. If a seller will not show the movement, treat the watch as fake.
Is buying a fake Cartier Tank Anglaise illegal in the US?
Yes. Counterfeit watches infringe a registered trademark, and US Customs and Border Protection can seize them at import. Buyers and sellers can both face civil liability, and selling at scale can bring criminal charges. A 1:1 copy is still a counterfeit in the eyes of the law, whatever the listing calls it.
What should you check before you buy?
- Ask for a clear macro photo of the crown set into the case flank.
- Request the reference and serial numbers and confirm them with Cartier.
- Ask for a movement photo and a weight in grams.
- Buy from a seller with documented service history and a return window.
- Have a watchmaker open the case before the return period ends.
What is the biggest tell on a fake Cartier Tank Anglaise?
The crown. Real ones sit inside a machined cutout in the case, while copies almost always sit on top of a standard tube with a visible gap underneath.
Do all Tank Anglaise watches have automatic movements?
No. Smaller sizes were offered with quartz movements and larger ones with automatic calibres, so a quartz watch is not automatically fake. Judge the case, dial, and bracelet first, then confirm the movement.
