Quick answer
A fake Ballon Bleu 36mm is a replica of the Cartier Ballon Bleu de Cartier 36mm. The genuine watch has a 36.6 mm steel case, an 11.2 mm thickness, a sapphire crystal, a fluted crown with a blue synthetic spinel, and 30 m water resistance. Replicas run from $60 quartz watches to $600 automatic copies. Case thickness, crown stone, dial print, and movement separate good copies from poor ones.

Replica build types
Three builds cover most of the market. A quartz copy costs $60 to $120 and runs a Ronda or Miyota quartz. A mid copy uses a Miyota 9015 or an Asia 2824 clone and costs $180 to $350. A top copy uses a Swiss ETA 2824 or Sellita SW200 and costs $350 to $600. Automatic copies add case thickness. Ask for a caliper photo of the case side.
Checks before you pay
Case and crown
Measure thickness. A number over 12 mm is a flag for an automatic copy. Look at the crown cabochon under light. The genuine stone is a deep blue synthetic spinel with a dome. Replicas use flat glass, plastic, or a stone with a purple tint. The crown guard should sit flush with the case band.
Dial and hands
Check the Cartier print with a loupe or a phone macro photo. Letters should have sharp edges and even spacing. The date font should be thin. Date wheels with bold or wide numerals point to a low-tier build. Hands should be blued steel with a brushed top and polished bevels. Printed hands look flat.

Bracelet and caseback
Genuine bracelet screws have a clean slot and sit flush. Engraving on the caseback is deep and crisp. Replica engraving looks shallow or laser-etched. Check the reference and serial numbers against photos of the same reference.
Price ranges and what they buy
- $60 to $120: quartz, mineral glass, flat crown stone
- $180 to $350: automatic clone, sapphire glass, better dial
- $350 to $600: Swiss movement, closer case thickness
Legal risk in the U.S.
Trafficking in counterfeit goods violates 18 U.S.C. § 2320. CBP can seize counterfeit watches at the border. Sellers face civil suits from the trademark owner. A replica label does not remove the risk. Buying for personal use does not make import legal.
What no guide can tell you
No public database tracks replica factories or batch numbers. Two watches from one seller can differ in case finish, movement, and dial print. Buy only with photos of the actual watch, a caliper reading, and a return policy.
