Short answer

33665 is a catalog number used by replica sellers. It is not a Cartier reference. Cartier Ballon Bleu references carry letter prefixes: W69012Z4 is the 33 mm steel automatic, W6920046 is a 33 mm steel automatic with a different dial finish, and W6920071 is the 33 mm steel and pink gold model. A search for 33665 points to a copy of the Ballon Bleu de Cartier, a model Cartier introduced in 2007.

The genuine Ballon Bleu at a glance

The case is round and domed, with a sapphire cabochon set in a fluted crown guard at 3 o'clock. The dial has a flinque finish, Roman numerals, and blued steel sword hands. The 33 mm version measures about 10 mm thick. Cartier fits the calibre 076, an automatic movement based on the Sellita SW200-1. It runs at 28,800 vibrations per hour, has 25 jewels, and holds a 38 hour power reserve. Water resistance is 30 m on the steel models.

What replica listings for 33665 describe

  • Case diameter: 33 mm. Some sellers list 36 mm or 42 mm under the same code.
  • Movement: quartz, Miyota 9015, or a clone of the ETA 2824-2. Quartz versions are thinner and cost less.
  • Crystal: mineral glass on low grades, sapphire on higher grades.
  • Case material: 316L stainless steel. Gold tone is plating, not solid gold.
  • Price: about $80 to $300, set by movement and case finishing.

Points to inspect

  1. Crown cabochon. Genuine watches use a sapphire. Low grade copies use blue glass or plastic.
  2. Dial print. Check the spacing of the Roman numerals and the shape of the Cartier script.
  3. Hands. Genuine hands are blued steel. Cheap copies use painted metal.
  4. Case back. Engravings on copies are shallow and often miss the Cartier reference format.
  5. Strap width. The 33 mm case takes a narrow strap. Measure the lugs before ordering a band.

Legal and practical notes

A replica is not a genuine Cartier watch. Cartier does not service copies, and no factory warranty applies. In the United States, trafficking in counterfeit goods is a federal crime under 18 U.S.C. 2320, and 19 U.S.C. 1526 allows customs to seize and destroy counterfeit merchandise at import. Buyers should know these rules before ordering.
