Short answer
"33663" is not a Cartier reference number. Cartier does not list a Ballon Bleu with those digits. The number shows up in replica seller catalogs as an internal SKU, most often for a steel Ballon Bleu with a blue cabochon crown. The same watch appears under different numbers on other sites.
Genuine Ballon Bleu references
Cartier Ballon Bleu references begin with W, WSBB, or CRW. Two examples are W69012Z4, a 42 mm steel automatic, and W6920071, a 33 mm steel model. Case sizes in the line are 28 mm, 33 mm, 36 mm, 37 mm, and 42 mm. Genuine movements include quartz caliber 057 and automatic calibers 076, 049, and 1847 MC. The crown sits under a blue synthetic spinel cabochon with a curved crown guard.
What replica listings state
- 316L stainless steel case, 33 mm or 36 mm
- Sapphire crystal on higher tiers, mineral glass on cheaper units
- Quartz, Miyota 9015, Sea-Gull ST2130, or a clone of the ETA 2824
- Caseback stamped with a Cartier reference that does not match the case size
Factory names change with each production run. Sellers list AF, V6F, 3K, BV, and others. No public record ties the number 33663 to one factory. Any claim about which factory built a specific unit is unverified.
US import law
Counterfeit watches are illegal to import into the United States. 19 CFR 133.23 lets US Customs and Border Protection seize goods that carry a counterfeit trademark. The Lanham Act, 15 U.S.C. 1114, gives the trademark owner a civil claim against sellers and importers. A single personal watch falls under a narrow exemption in some cases. A shipment of counterfeits does not. Seized goods are destroyed, and the buyer has no refund path through CBP.
Price gap
Replica Ballon Bleu listings run about $200 to $600. New steel Ballon Bleu watches from Cartier sell for roughly $5,000 to $9,000. A replica carries no Cartier warranty, no Cartier service, and no resale market. Cartier service centers refuse counterfeit pieces, so repairs go to independent watchmakers.
How to read a listing
- Ask for the reference stamped on the caseback. Compare it to Cartier's own model pages.
- Ask for photos of the movement, not stock images.
- Ask for the customs policy in writing before payment.
Point 3 matters because the seller, not the buyer, controls the shipping declaration. If the parcel is held, the money is gone and the watch is not delivered.
