Short answer
A replica Cartier Panthère 2021 is a copy of the Panthère de Cartier sold in that year. The genuine 2021 Panthère came in three sizes: small at 22 x 30 mm, medium at 27 x 37 mm, and large at 31 x 42 mm. All three ran on quartz movements. Replica units from 2021 sold for $30 to $400. Most used 316L stainless steel, plated gold, and a quartz movement from Ronda, ETA, or an unnamed factory. Cartier did not make a Panthère at those prices or in those materials.
What the 2021 Panthère is
Cartier launched the Panthère in 1983. The line returned to the catalog in 2017. The 2021 range kept the same case shape: a square bezel with rounded corners, a crown set with a blue sapphire cabochon, and a link bracelet. Steel models have a smooth bezel. Gold models have eight visible screws on the bezel. The dial carries Roman numerals, a chemin de fer minute track, and no date window. Case thickness is about 6 mm. Water resistance is 30 m.
Replica tiers in 2021
- Low tier, $30 to $80: alloy case, mineral glass, unbranded quartz, gold paint over brass.
- Mid tier, $100 to $200: 316L steel case, sapphire glass on some units, Japanese or Swiss quartz, PVD plating at 3 to 5 microns.
- High tier, $250 to $400: 316L steel, sapphire glass, Swiss quartz, gold plating at 10 microns, working bezel screws.
Tier labels come from sellers, not from a standard. One factory can ship the same case to three sellers who list it at three tiers.
Points to check
- Sapphire cabochon: a real stone on genuine units, glass or plastic on most replicas. Both are blue.
- Bezel screws: genuine gold models have eight screws with slots aligned to one direction. Replica slots sit at random angles.
- Bracelet joints: genuine links close with no gap. Replica links show gaps at the fold.
- Dial print: the Cartier script is thin and sharp on genuine dials. Replica print is thicker and sits high on the surface.
- Case back: genuine units carry a model number and a unique serial number. Replica numbers repeat across units from the same batch.
- Movement: genuine quartz ticks one time per second. Most replicas also tick one time per second, so this test does not separate the two.
Prices for the genuine watch
In 2021, steel Panthère models listed between $3,000 and $4,500 at retail. Yellow gold and rose gold models listed above $10,000. Cartier does not publish production numbers, so total 2021 output is unknown. Resale prices track metal content more than model year.
Legal status in the US
Counterfeit watches are illegal to import and sell in the United States. 18 U.S.C. § 2320 sets a prison term of up to 10 years for trafficking in counterfeit goods. US Customs and Border Protection seizes counterfeit shipments and can destroy single units bought for personal use. Resale carries more risk than personal possession. Sellers who ship from outside the US add a customs step to every order.
Market notes
Replica prices track the tier, not the genuine retail price. A listing at $900 is not better than one at $350 without photos of the movement and the case back. Terms like "clone" and "1:1" have no fixed meaning in the trade. Ask for the movement name, the case material, and the plating thickness in microns. Sellers who cannot answer those three points are reselling the same low tier stock under a new name.
