Short answer
A knockoff Cartier Panthère 2020 is a replica of the Panthère de Cartier as catalogued around the 2020 model year: a quartz watch in small (22 x 30 mm), medium (27 x 37 mm) and large (30 x 40 mm) cases, built in steel, steel with yellow gold, rose gold and yellow gold, with diamond-set bezels on some references. The design is simple, so the replica tells are consistent and easy to learn: case thickness, the crown cabochon, dial printing, bracelet link fit, and crystal material. Judge a listing against the reference it claims to copy, not against the seller's studio photos.
Before you look at listings
- Pick a size. The small and medium models are the common 2020 references, and both wear wider than their millimeter numbers suggest because the case is rectangular.
- Confirm the movement type you expect. The 2020 Panthère line was quartz, with a ticking seconds hand. A listing that advertises an automatic Panthère is not copying a 2020 reference.
- Know the law in your country. Counterfeit watches that carry a trademarked logo and name are illegal to sell and to import into the United States.
- Set a budget band before you compare sellers, so a low price does not pull you past the checks below.
How to check a replica Panthère step by step
- Measure the case with calipers. Small should read close to 22 x 30 mm and medium close to 27 x 37 mm, with a thickness in the 6 mm to 7 mm range. Replicas often run one or two millimeters large, which throws off the proportions of the bezel.
- Examine the crown cabochon. The genuine piece uses a faceted blue sapphire or spinel set into the crown. Replica cabochons are glass or dyed plastic, and they look cloudy or already scratched.
- Read the dial under a loupe. Check the Roman numerals, the CARTIER signature, and SWISS MADE at 6 o'clock. Cartier works a small secret C into one of the numerals, most often the VII, and on replicas it is missing, oversized, or placed in the wrong numeral.
- Flex the bracelet. The brick-link bracelet should move as one piece, with even gaps and no sharp edges where the links meet. Loose joints, rolled edges and pins that strip when you size the watch are common replica faults.
- Test the crystal. Drag a fingernail across it. Sapphire resists the scratch test; mineral glass and acrylic do not. Also check the anti-reflective coating, which genuine Panthère crystals lack on the top surface.
- Inspect the caseback engraving. Reference numbers, serials and the Cartier name should be cut deep and crisp, not laser-etched shallow or stamped off center.
- Watch the seconds hand run. A quartz Panthère ticks once per second. A stuttering or skipping hand points to a low-grade movement or a weak battery.
- Ask about water resistance. The genuine watch is rated to 3 bar. Most replicas have no gasket system worth trusting, so treat any splash claim as marketing.
Red flags
- A seller who claims 1:1 quality but will not show the caseback or a close photo of the dial print.
- Photos borrowed from a boutique or a review site instead of images of the actual watch.
- A shipping offer that hides the watch as a gift or samples to clear customs.
- No reference number, no size given, and no return window.
