The search term fake ballon bleu 33687 joins a model name to a number that is not part of Cartier's reference system, and that mismatch is the first thing to understand before you spend money. If you want a Ballon Bleu, buy from an authorized Cartier boutique, an authorized dealer, or a documented pre-owned seller who lists the true reference number and serial. Sellers who advertise a watch as a fake or replica of a named reference are offering an infringing product. In the United States the import and sale of counterfeit goods is illegal, so a buyer ends up with no manufacturer warranty, no service path, and a genuine chance of seizure at the border.
What the number 33687 actually refers to
Cartier reference numbers for the Ballon Bleu follow a letter-based pattern, generally starting with a W or with the newer WSBB prefix, followed by digits and letters. A five-digit number like 33687 in a listing title is usually a marketplace item ID, a seller batch code, or an internal stock tag. It tells you nothing about the watch. When a title leans on a code instead of a reference, treat it as a signal that the seller has no verifiable product identity to offer.
How to inspect a Ballon Bleu before you commit
Case, bezel, and crown
The Ballon Bleu takes its name from the crown, which sits inside a curved guard and is capped with a blue cabochon. On genuine pieces that cabochon is a polished stone set flush at the correct angle. On counterfeits it is often plastic, cloudy, or tilted, and the guard looks stamped rather than hand-polished. Check the bezel profile too. Genuine case flanks curve in two directions, which is expensive to machine and rarely reproduced well.
Dial and hands
Look at the printed text under magnification, the alignment of the Roman numerals, and the finish on the sword hands. Counterfeit dials tend to have heavier printing, uneven spacing, a weak cyclops magnifier over the date, and hands that are painted rather than blued. The dial texture on guilloche models is shallow and repeated poorly.
Movement and caseback
Current steel Ballon Bleu models run Cartier's in-house 1847 MC automatic calibre, while older generations used other automatic movements. A genuine caseback carries deep, crisp engraving and a serial that matches the paperwork. Fakes often show shallow laser etching, mismatched screws, and an unbranded movement visible through the back.
Box, papers, and serials
The serial on the caseback should match the certificate and the boutique record. Counterfeit sellers reuse the same serials across many listings, which is easy to catch with a basic search. Cartier can confirm a serial through an authorized boutique or service center.
Parameter bands worth knowing
- Case diameter: 33 mm, 36 mm, 37 mm, 40 mm, and 42 mm across generations and lines
- Materials: stainless steel, steel with rose or yellow gold, solid gold, and platinum
- Movement: automatic, with the 1847 MC in most current steel references
- Water resistance: modest on classic dress references, higher on sport-oriented versions
- Bracelet: steel with a concealed folding clasp, or an alligator leather strap
Match the diameter to your wrist first. A 33 mm to 36 mm case reads as a classic dress watch, while 40 mm and above sits much larger. Confirm the material and bracelet type, because those two factors drive value more than any other specification.
Pitfalls to avoid
- Listings using terms like AAA, 1:1, or mirror quality, which describe a counterfeit grade, not a watch
- Sellers who push payment off the platform and offer no returns
- Photos borrowed from genuine watch listings or from other sellers
- Claims of Swiss movement on a watch with no serviceable parts network
- No serial, no certificate, and no answer when you ask for the reference number
FAQ
Is 33687 a Cartier reference number?
No. Cartier references for this model use a W or WSBB prefix. A five-digit code in a title is a marketplace or seller identifier.
Can a jeweler tell a fake Ballon Bleu from a real one?
Usually yes, and quickly. Case finishing, cabochon quality, dial printing, and movement decoration are the usual giveaways.
Will Cartier service a counterfeit watch?
No. Authorized service centers decline counterfeit pieces, and the watch may be withheld. That removes the main reason to own a mechanical watch at all.
What happens if a counterfeit watch is shipped to the United States?
Customs can seize and destroy it. The buyer loses the money and has no legal recourse against the seller.
