Short answer
A replica Cartier Tank Cintrée is a copy of a watch Cartier has made since 1921. The case is long, narrow and curved, and that curve is the point of the design. Most replicas get the outline right and the curve wrong, so the watch sits flat on the wrist instead of wrapping it. If you are comparing sellers, the case curve, the dial print and the movement are the three things worth your attention.
What the original does
Cartier released the Tank Cintrée in 1921 as a stretched version of the Tank. The 2021 reissue measures about 46.5 mm from lug to lug and 23 mm across, with a hand-wound Cartier 9780 MC movement inside. Tapered brancards bend along the case so the watch follows the wrist. The dial carries Roman numerals, a chemin de fer minute track, blued steel hands and, on most versions, a crown set with a sapphire cabochon.
What the grading labels mean
Sellers use terms like AAA, 1:1, Swiss grade and super clone. None of these are official and no factory publishes a standard behind them. They are shop labels, and two sellers can apply the same word to very different watches. Treat the label as a starting point and judge the watch itself.
How to evaluate one before you pay
- Ask for the exact dimensions in millimeters and compare them to the 46.5 by 23 mm reference. A copy that measures 44 by 22 mm will look short on the wrist.
- Request a side profile photo next to a ruler or a coin. Look for a case that bends along its length. A flat case with curved lugs is the most common shortcut.
- Check the dial print at high magnification. Roman numerals should have crisp serifs, the minute track should be even, and the Cartier name should sit inside the correct sector.
- Ask which movement is inside. Hand-wound copies exist, but many budget builds use quartz or a small automatic. Get the caliber name and a photo of the movement.
- Inspect the crown. The cabochon should be a smooth dome with a color that matches the stone in the photos, not a plastic bead with a visible seam.
- Ask for the thickness. The original is thin, near 7 mm. Copies that measure 10 mm or more sit high and read as bulky.
- Confirm the strap and buckle. The original uses an alligator strap with a matching gold or steel pin buckle. Ask whether the strap is real leather or synthetic.
- Ask about water resistance and service. Most replicas are never pressure tested, and movement parts may not be available later.
Movements you will find
Three categories show up. Quartz copies are cheap and accurate, and since the Cintrée is a two-hand watch the giveaway is the crown action rather than a sweeping hand. Automatic copies add a rotor, which makes the case thicker. Hand-wound copies come closest in feel to the 9780 MC, and some use decorated clones of common Swiss manual calibers.
Legal and practical notes
- Cartier holds registered trademarks on its name and on the Tank line. Selling or importing a copy that carries those marks can lead to seizure at customs and to civil claims in the United States.
- No replica carries a manufacturer warranty. Repair depends on the seller, and parts supply is not guaranteed.
- Resale value is close to zero. Buy a copy as a wearable, not as an asset.
- Vintage Cintrée models sell at auction in the five-figure range, so any "genuine" Cintrée offered near replica prices is not genuine.
Bottom line
Judge a replica Cartier Tank Cintrée on the case curve, the dial print and the movement. Get photos with measurements, ask for the caliber, and skip any listing that will not answer either question.
