The code 33701 is the case reference stamped on the back of the Cartier Ballon Bleu de Cartier 42 mm stainless steel automatic. A "fake Ballon Bleu 33701 replica" is a counterfeit built to imitate that specific model. The number is not a model name and it is not a grade of quality. It is a factory code, and sellers borrow it because buyers search for it. The tells that separate a real 42 mm Ballon Bleu from a copy sit in the dial printing, the crown cabochon, the caseback engraving, the movement, and the weight.
Counterfeit Ballon Bleu 33701: How to Spot Fakes and Buy Authentic
What 33701 Refers To
Cartier stamps a case number on the back of every watch, separate from the model name on the papers. The Ballon Bleu debuted in 2007 and became the brand's most recognizable round case. The 42 mm steel version carries a self-winding movement, a flinqué guilloché dial, an integrated steel bracelet, a sapphire cabochon set into the crown, and an arched crown guard that curves around the crown without touching it. The case runs roughly 42 mm across and about 13 mm thick.
Why Sellers Put the Number in Listings
Case references circulate on owner forums, auction archives, and service records, so they are easy to copy. A listing that leads with "33701" sounds precise and ranks in search. The number tells you nothing about the watch being sold. Judge the photos, the movement, and the paperwork instead of the code in the headline.
How to Spot a Counterfeit Ballon Bleu 33701 Bracelet: The Ultimate Guide
Replica Grades You Will See Advertised
- AAA or A-grade. Usually a plated case, mineral glass, and a basic quartz or low-tier automatic movement.
- 1:1 or Swiss made. Marketing terms with no standard behind them. Most watches in this bracket use a Miyota 9015 or a Seagull ST2130 with a decorated rotor.
- Super clone. The closest tier. Case geometry and bracelet are copied well, but the movement is a Chinese automatic with engraved bridges, not the Cartier calibre 049.
Inspection Steps
- Request a straight-on macro photo of the dial. Genuine printing is crisp at 10x, with sharp serifs on the numerals and even spacing.
- Study the crown cabochon. Real sapphire has a deep blue tone and a polished dome. Glass and resin look flat, cloudy, or too bright.
- Confirm the diameter. A 40 mm case sold as 33701 is the wrong model.
- Trace the crown guard arch. It should form one continuous curve. Copies often show a stamped ridge or a gap where the arch meets the case.
- Check the guilloché. The concentric pattern stays even out to the edge on a genuine dial and blurs near the center on most copies.
- Ask for a movement photo. The 42 mm uses the Cartier calibre 049, based on the ETA 2892-A2, finished with Côtes de Genève and correct rotor engraving.
- Weigh the watch. A steel 42 mm Ballon Bleu on its bracelet runs roughly 110 to 130 grams. Copies usually come in lighter.
- Ask who services it. No independent watchmaker can source genuine Cartier parts for a counterfeit, and Cartier will not touch it.
Risk in the United States
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. 2320, and trademark owners can pursue civil claims under the Lanham Act. US Customs and Border Protection seizes counterfeit watches at the border and destroys them. A buyer who loses a shipment has no refund path and no legal standing to recover the item. Beyond the legal exposure, there is no warranty, no service, no resale value, and no way to confirm what metals or platings sit against your skin.
Checking a Watch That Claims to Be Genuine
Ask for the original warranty card, the serial number on the caseback, and a recent service invoice. Have the numbers matched by an authorized dealer or a paid authenticator before money changes hands. A genuine pre-owned Ballon Bleu holds value and can be serviced. A counterfeit does neither.
