Short answer
A white-dial Cartier Tank Must is simple enough to copy in photos and hard to copy in person. Fakes get the rectangle and the Roman numerals right. They miss the dial texture, the case finishing, the crown, and the caseback engraving. If you have the watch in hand, compare those four things first.
What the real Tank Must white dial is
Cartier brought the Tank Must back in 2021 as its steel entry-level Tank. The white version uses an opaline or lacquered silver-white dial, black printed Roman numerals, a chemin de fer minute track, and blued-steel sword hands. The Large steel case measures about 33.7 mm wide by 25.5 mm tall and roughly 8.4 mm thick, with a brushed top surface and polished flanks. Steel models carry a blue synthetic spinel cabochon in the crown rather than a sapphire. Quartz is standard, and SolarBeat versions run on light. There is no seconds hand, so a sweeping second hand is an instant tell.
Dial details that give a fake away
- Texture. The real dial has a fine, even sheen that shifts with the light. Copies tend to be flat white, chalky, or too glossy.
- Print. Roman numerals on the real piece have crisp edges and consistent stroke weight. Fakes show thick or fuzzy printing, uneven spacing, and a minute track that crowds the numerals.
- The hidden signature. Cartier hides the word CARTIER inside the VII numeral. On fakes it is often missing, too bold, or drawn as a smudge.
- Hands. Sword hands should be blued steel with a clean edge and correct length. Replicas use painted or heavily lacquered hands that read black rather than blue.
Case, crown, and finish
Run a finger along the case. Real Tank Must cases have a brushed top, polished sides, and a crisp line between the two. Fakes round that transition off or polish the whole case. The crown sits centered on the 3 o'clock flank, and the cabochon is domed, evenly set, and matched in color. Off-center or flat cabochons, oversized crowns, and lugs with soft edges are the usual problems.
Caseback, serial, and papers
The steel caseback is engraved, not laser printed. Lettering is shallow but sharp, with a reference number and a serial that match the paperwork. Price is a fast filter: a steel Tank Must Large sells in the low four figures new, so a sealed one at a tenth of that is not a bargain. Buying from an authorized dealer or a pre-owned seller with service records removes most of the risk. If you already own one and want certainty, a watchmaker or a Cartier service center can confirm the movement and case. Importing counterfeit watches into the United States is illegal, and shipments get seized.
