Short answer
Cartier's public catalog lists Ballon Bleu references as W-prefixed codes. Examples: W69012Z4 for the 42 mm steel model, W69010Z4 for the 36.6 mm steel model. No reference 33741 appears in that system. The number 33741 turns up on replica listings and on some case-back stamps. A listing built on that number is making an unverified claim.

The Ballon Bleu line
Cartier released the Ballon Bleu de Cartier in 2007. The case is round. The crown sits inside a metal guard at 3 o'clock and holds a blue synthetic spinel cabochon. Dials are guilloché, most often in a sunray or flinqué pattern. Case sizes run from 28 mm to 46 mm. Movements include the 057 quartz caliber and the 049 automatic caliber; later pieces use the 1847 MC.

How replicas get identified
- Cabochon: a real spinel is a smooth dome with no seam. Copies use glued glass and show adhesive at the edge.
- Crown guard: the curve runs into the case with no gap and no tool mark.
- Dial print: "CARTIER" and "SWISS MADE" stay crisp under 10x magnification.
- Case back: engraving depth and font. Reference, case number and serial sit in a fixed layout.
- Movement: case-off photos show finishing, jewel count and rotor engraving.
- Weight: steel models run heavier than plated brass copies.
Legal status in the US
Counterfeit watches are illegal to import and sell in the United States. 19 U.S.C. § 1526 lets Customs and Border Protection seize and destroy them. The Lanham Act, 15 U.S.C. § 1114, covers trademark infringement. Trafficking in counterfeit goods carries up to 10 years and a $2 million fine for a first offense under 18 U.S.C. § 2320. Buying a counterfeit for personal use does not create a safe harbor for the seller.

What a listing cannot show
Listing photos seldom show the movement. Serial numbers on copies get reused across batches. Cartier does not run a public serial lookup for the Ballon Bleu. A boutique or an authorized service center can confirm a reference and a service record during a hands-on inspection.
