Short answer

Cartier does not make a Tank Must chronograph. The Tank Must line has a three-hand dial, no subdials, and a quartz movement. Any listing that uses the phrase "fake Cartier Tank Must chronograph" describes a watch Cartier never built. The item in the photo is either a Tank Must copy with pushers added, or a different Cartier chronograph sold under the wrong name.

What the Tank Must is

Cartier relaunched the Tank Must in 2021 as the entry steel model. Two sizes: small at 29.5 x 22 mm and large at 33.7 x 25.5 mm. Sapphire crystal, steel case, faceted crown with a blue spinel cabochon, leather strap or steel bracelet. Movement is quartz. There is no chronograph reference in the collection. US retail has run from about $3,000 to $3,600 since launch. Cartier changes prices, so check the current figure at the source.

Cartier chronographs that do exist

  • Santos Chronograph
  • Ballon Bleu Chronograph
  • Calibre de Cartier Chronograph
  • Tank Francaise and Tank Americaine chronograph versions from the 2000s
  • Roadster Chronograph, discontinued

None of these carry the Tank Must name. A seller who swaps one name for another is hiding which watch the copy imitates.

Why the name shows up in listings

"Tank Must" pulls search traffic. "Chronograph" adds subdials, which make a cheap quartz movement look complex. Sellers stack both words, then ship a generic case. Prices on these listings run from $60 to $400. Stock photos and overseas shipping are common.

Checks on a listing

  1. Model check. Search the reference number on the Cartier site. Tank Must references start with WSTA.
  2. Subdial check. A 33 mm Tank Must case has no room for three subdials at correct spacing. Pushers at 2 and 4 o'clock do not appear on any Tank Must.
  3. Dial print. Cartier dials have sharp edges on the Roman numerals and the minute track. Copies show thick, uneven print and ink bleed.
  4. Secret signature. On several Cartier dials the word CARTIER is drawn inside the VII numeral. Check with a loupe.
  5. Crown. Faceted steel with a blue spinel cabochon. Copies use plastic or glass, often too round or too blue.
  6. Caseback. Real watches carry laser engraving with reference, case number, and Swiss Made. Copies show shallow engraving and reference numbers that do not match the papers.
  7. Movement. Tank Must is quartz. A seconds hand that jumps once per second is normal. A "chronograph" with quartz subdials and Swiss Made stamps is a mismatch.

Price reality

A genuine Tank Must starts near $3,000. A mechanical chronograph movement costs more than a quartz three-hand movement. A $150 watch with the words "Swiss super clone" does not contain a Swiss chronograph caliber. Ask for a photo of the movement and the caseback. Sellers who cannot supply either are selling a quartz case with decoration.

Legal note, US

Trafficking in counterfeit goods is a federal offense under 18 U.S.C. 2320. US Customs and Border Protection seizes counterfeit watches at ports of entry. A seized shipment is lost, and the buyer has no claim against the seller.
