Short answer
Cartier does not make a Tank Must bangle. The Tank Must is a watch line. Any item sold as a "Cartier Tank Must large bangle" is a third-party piece that carries Cartier marks without Cartier's approval. Under US law that item is a counterfeit, not a replica.

What Cartier sells under those names
Cartier introduced the Tank watch in 1917. Must de Cartier was an entry-level line in the 1970s and 1980s. Cartier brought the name back in 2021 as the Tank Must watch, a steel quartz and SolarBeat model. Cartier bangles and bracelets sit in other lines: Love (1969), Juste un Clou (1971), and Trinity (1924). A search for a Tank Must bangle returns no product page on cartier.com.
Replica Cartier Tank Must Large vs Small Bangle: Which Size to Pick
What the replica market sells
Listings that use this phrase describe a rigid bangle, not a watch. Common specs: 316L stainless steel base, gold plating between 0.5 and 3 microns, cubic zirconia or moissanite in the stone settings, and laser engraving of Cartier text, size numbers, and a serial. Weight runs 20 to 40 grams by size. A Cartier bangle in the same shape would be 18k gold and marked with a French or Swiss assay hallmark.
Diamond claims
Most listings that say "with diamonds" ship with cubic zirconia. Some use moissanite. Both look white and both fail a diamond tester. The FTC Jewelry Guides require sellers to disclose simulated stones and laboratory-grown stones. A listing that says "diamonds" with no qualifier and no grading report makes a claim you cannot verify.
Cartier Tank Must Large Fake vs Original: Which One Holds Up
Legal status in the US
Cartier is a registered trademark of Richemont. Selling an item that carries the mark without a license is infringement under 15 U.S.C. § 1114. Trafficking in counterfeit goods is a federal crime under 18 U.S.C. § 2320, with up to 10 years in prison for a first offense and fines up to $2 million for an individual. Civil damages reach $2,000,000 per mark per goods type when the use is willful. CBP can seize shipments at import under 19 U.S.C. § 1526.
Personal purchase for use is not the same as selling. Import remains a seizure risk.
Points to check before you buy
- Stone type and count in writing, with a tester result if the seller claims diamond.
- Plating thickness in microns, stated as a number.
- Metal base: steel, brass, or gold. Brass tarnishes.
- Hallmark. 18k Cartier gold carries a French eagle head or a Swiss hallmark plus a serial.
- Service. Cartier will not service, size, or authenticate an item it did not make.
- Resale. No auction house or dealer will take a counterfeit piece.
Bottom line
The phrase describes a product Cartier does not sell. Any version of it is a brand name copied onto a bangle. Materials, stones, and legal exposure are the three things to weigh. Facts on the stone and the metal are hard to get from most listings.
