Short answer: a good "clone" Tank Louis gets the silhouette right. The 33.7 by 25.5 mm gold dress case, the brancard lugs, the rail-track minute scale and the Roman numerals can all be copied well enough that you need a loupe, a scale and calipers to tell them apart. What clones get wrong is the stuff you can't see in a product photo: the movement, the gold, the caseback finishing and the crown cabochon. And no replica holds value, gets serviced by Cartier, or can legally be sold as genuine.

What "clone" means in the Tank market
Sellers throw around three words loosely. "First copy" usually means a cheap quartz piece. "1:1" claims the dimensions match. "Clone" or "super clone" means the maker tried to match the case, dial and a manual-wind movement with two hands and no date. On the Tank Louis, that last detail matters. The real watch has hours and minutes only. A replica with a small seconds subdial or a date window at 3 is wrong before you even look at the printing.
The details that give a fake away
- Thickness. The genuine large Tank Louis sits around 6.6 mm tall. Plenty of replicas run a full millimeter thicker, which changes how it sits under a cuff.
- Weight. Solid 18k gold feels dense. Gold-plated brass or steel cases come in noticeably lighter in the hand.
- Cabochon. The crown stone should be a domed synthetic sapphire set into the fluted crown. Fakes use glass or plastic, often too flat or too vividly blue.
- Dial printing. Look at the rail track and the serifs on the numerals. Good replicas are crisp. Cheap ones are soft and slightly raised.
- Hands. Genuine hands are blued steel. Replicas are usually painted, and the color reads flat under a light.
- Hallmarks. Gold stamps and caseback engraving are where most fakes fall apart. They are shallow, misaligned or missing.
Where the money actually goes
Movement is the whole game. A $40 quartz Tank is a costume piece. The $150 to $250 tier usually adds a decorated automatic, which is historically wrong for this watch. Above roughly $350 to $600 you reach manual-wind replicas with decent finishing, and that is the only tier worth comparing to the real thing. Even then, expect a movement no watchmaker will stock parts for.

Sizing and feel on the wrist
The large model reads small by modern standards, which is the point. The small model, around 29.5 by 22 mm, is closer to a vintage proportion and looks delicate on most wrists. Try the size on before you commit, because a replica in the wrong size will never feel right no matter how good the dial is.

The part people skip
Counterfeit goods carrying a registered trademark are illegal to import into the United States. Shipments get seized, and selling a replica as genuine is fraud. Resale value is effectively zero, and Cartier will not touch the watch for service. Buy a replica as a fun object if that is your call, but treat it as disposable, and never represent it as real.
