Short answer

A buying guide for counterfeit Cartier Tank Must watches is not something I can write. Trafficking in counterfeit watches is illegal in the United States, and the buyer carries all the risk: no warranty, no service, no dispute rights worth using, and a watch that may be seized at import. The useful version of this question is how to tell a copy from a genuine Tank Must before money changes hands, and how to buy the real thing for less than boutique retail. That is what follows.

What the cor de chasseur name actually refers to

The Tank Must returned to Cartier's catalog in 2021 as a steel Tank with a quartz movement and a set of colored lacquer dials. Cartier labels those dials with plain color names on its own product pages. Ornamental French shade names such as cor de chasseur, a rust and oxblood tone, appear mainly in marketplace listings and forum threads rather than in the brand's published references. When a seller leads with a poetic color phrase instead of a reference number, that is the first signal you are looking at a copy being marketed as a rarity.

Where the copies come apart

  • Case geometry. The large Tank Must measures roughly 33.7 by 25.5 mm and the small roughly 29.5 by 22 mm, with a slim profile and sharp lug angles. Copies run thick and the curve of the lugs is wrong.
  • Dial printing. Genuine dial text is crisp and evenly spaced. Fakes show bleeding edges, crowded letters, or a Roman VII with the wrong stroke weight.
  • Crown cabochon. Real Tank Must crowns carry a blue synthetic spinel. Copies use plastic or dyed glass that looks flat under light.
  • Movement and caseback. The genuine watch runs a Cartier high autonomy quartz caliber with an engraved caseback and reference. Counterfeits use unbranded movements with no parts supply.
  • Serial matching. Genuine numbers are engraved and traceable to Cartier records. Copies are printed or reused across batches.

How to verify before you buy

Ask for clear photos of the caseback, the crown, and the dial at an angle so you can judge the printing. Confirm the reference number against the official product page. Buy from a seller with a long documented history and pay with a method that gives you dispute rights. Have a Cartier boutique or a qualified watchmaker open the case before the return window closes. A genuine pre-owned Tank Must holds value and can be serviced for decades. A copy cannot be serviced by Cartier, and most independent watchmakers cannot source parts for it, so a failed counterfeit is a total loss.

FAQ

Is buying a counterfeit watch illegal in the US?

Trafficking in counterfeit goods is illegal, and Customs and Border Protection seizes counterfeit watches at import. The personal use exemption that applies to some categories of goods does not cover trademark counterfeits.

What should a genuine Tank Must cost?

Pre-owned pricing moves with condition, dial color, and whether box and papers are included. Compare several completed sales on established pre-owned marketplaces instead of trusting one asking price.

Can a watchmaker repair a counterfeit?

Rarely. Cartier will not service or authenticate a counterfeit, and parts for generic movements inside copies are often unavailable or wrong for the case.

Do color names like cor de chasseur come from Cartier?

Cartier publishes straightforward color names for the Tank Must dials. Ornate French shade names usually come from resellers. Check the official reference for the exact watch you are considering.
