Quick answer
A Cartier Tank Must red copy is a replica of the steel Tank Must with the red lacquer dial that Cartier launched in 2021 under the Les Must de Cartier revival. The genuine watch measures 33.7 mm by 25.5 mm, runs on quartz, and has no date. A first copy grade replica repeats those dimensions and the dial color. It is not made by Cartier. It has no Cartier warranty, and Cartier service centers will not work on it.

Dial and printing
The red dial is the point of this reference. Low grade copies print red ink on a white base or lay a red decal over a silver plate, so the color goes flat at the edges and looks orange under warm light. Better grades use a lacquer finish with a gloss that shifts under direct light. Roman numerals on the genuine dial are printed, not applied, so no metal edge catches light. The minute track, the SWISS MADE text at 6 o'clock, and the Cartier signature at 12 o'clock sit in fixed spots. Check the letter spacing in the signature. Blur or crowding there is the fastest tell.
Cartier Tank Must Red Counterfeit Guide
Case, crown, and cabochon
The Tank Must case is polished steel. The crown sits at 3 o'clock and holds a blue synthetic spinel cabochon on the genuine watch. Replicas often fit a red or dark glass cab. Check the color and the dome shape. Case thickness matters too. A copy with a thick mid case will not sit flat on the wrist, and the crystal will stand proud of the bezel.

Movement and feel
The genuine red Tank Must uses quartz, so the second hand ticks once per second on both the real watch and a copy. Sweep is not a tell here. What differs is the caseback, the engraving depth, the serial style, and the screw heads. First copy quartz movements come from Ronda, ETA, or Miyota. Cartier lists a long battery life for the Tank Must caliber. Copies use standard cells that need replacement sooner. Caseback text on copies is laser etched and shallow. Genuine engraving is deeper and clean at the edges.
Strap and buckle
Red dial models ship on a red calfskin strap with a steel pin buckle and Cartier QuickSwitch spring bars. Copies ship with generic spring bars and thinner leather. Check the engraved text on the buckle and the stitch count per centimeter.
What a copy cannot do
- No Cartier warranty or service. Cartier refuses counterfeit watches and can hold them.
- No resale value. Replica listings resell for a fraction of the price paid.
- No provenance. Serial numbers and papers do not match Cartier records or a boutique receipt.
Legal note in the US
Counterfeit watches are illegal to import and sell in the United States. U.S. Customs and Border Protection can seize shipments. The Lanham Act gives Cartier and other trademark owners civil claims against sellers. A personal purchase is not the same as a sale, but the goods stay subject to seizure at the border.
