A fake Cartier Tank Cintrée is a counterfeit version of the curved-case dress watch Cartier introduced in 1921, and the fastest way to identify one is to check three things: whether the case curves in two planes, whether the crown carries a genuine sapphire or spinel cabochon, and whether the movement is a hand-wound Cartier calibre. Replicas almost always fail at least one of those checks.

What is the Cartier Tank Cintrée?

The Tank Cintrée is an elongated rectangular wristwatch whose case is bent to follow the curve of the wrist. "Cintrée" is French for "curved," and the model debuted in 1921, two years after the original Tank. Genuine examples measure roughly 46 mm from lug to lug and 23 mm across, which makes it one of the longest and thinnest Tanks Cartier has produced.

Cartier has issued the Cintrée in platinum, yellow gold, and rose gold, usually in small runs. Because supply is tight and demand is steady, the model sits among the more frequently counterfeited Cartier shapes.

How do you tell a fake Cartier Tank Cintrée from a real one?

Start with the case profile. A genuine Cintrée curves in two directions at once, following both the length and the width of the wrist. Most replicas bend along one axis only, so they sit flat or rock when worn.

• Case profile: two-plane curvature on the real watch; replica cases are typically single-curved and noticeably thicker than the genuine 7 mm.
• Crown: faceted, with a blue sapphire or spinel cabochon set flush. Fake stones are often glass, glue-set, or swapped for a plain blue bead.
• Dial: crisp Roman numerals, a fine railway minute track, and the word "Cartier" worked into the VII numeral on many references. Replica dials show fuzzy printing and misaligned tracks.
• Hands: blued steel, sword-shaped, finished on all sides. Replicas use painted or chemically blued hands with ragged edges.
• Movement: a hand-wound Cartier calibre such as the 9780 MC, visible through a sapphire caseback. A rotor on a Cintrée is an immediate red flag because the real watch is manual-wind.
• Caseback: engraved reference and serial numbers that match Cartier records, with correctly spaced "Swiss Made."
• Weight: solid gold feels dense; plated brass and steel replicas feel light and ring differently when tapped.

How much does a fake Cartier Tank Cintrée cost?

Replica pricing falls into three rough tiers. Entry-level quartz copies sell for $50 to $200, mid-tier mechanical copies run $250 to $600, and the better "super clone" builds ask $700 and up. Genuine Cintrée examples trade in the five-figure range on the secondary market, which is why the price gap draws buyers.

What are the legal risks of buying a fake Cartier Tank Cintrée?

Counterfeit watches infringe Cartier's trademarks, and trafficking in them is a criminal offense in the United States under 18 U.S.C. § 2320. Importing a counterfeit item can lead to seizure by U.S. Customs and Border Protection under 19 U.S.C. § 1526, even when the buyer intends personal use. Buyers also get no warranty, no service network, and no resale value.

Do replica Tank Cintrée watches keep good time?

Quartz replicas usually keep accurate time but carry no collector value. Mechanical replicas often run within plus or minus 20 to 30 seconds per day and are rarely water-resistant beyond splash level. No replica is serviceable by Cartier, so any repair falls to a local watchmaker using generic parts.

Is the Tank Cintrée the most copied Cartier model?

No. The Tank Must, Tank Louis Cartier, and Santos are counterfeited far more often because they sell in larger volumes. The Cintrée's curved case is harder and costlier to reproduce, so fakes of it are fewer but frequently cruder.

Bottom line

A fake Cartier Tank Cintrée reveals itself through case curvature, crown stone, dial printing, and movement type. If the watch curves in only one plane, shows a rotor, or carries a glass cabochon, it is not genuine.
