A fake Ballon Bleu Extra Large is a counterfeit copy of Cartier's 42 mm Ballon Bleu de Cartier, the largest three-hand version of the line. The genuine watch pairs a rounded steel or gold case with a blue cabochon crown, a guilloché dial, and a signed automatic movement. Replicas seldom match the case diameter, the cabochon material, and the dial finishing all at once.
What does "Extra Large" mean in the Ballon Bleu line?
Cartier sizes the Ballon Bleu by case diameter rather than by name, with models spanning roughly 28 mm to 42 mm and chronograph versions running larger. Sellers use Extra Large for the 42 mm automatic, and some apply the label to 46 mm chronographs. Measure the case across the back, without the crown, before you trust any label.
How do you spot a fake Ballon Bleu Extra Large?
Most fakes fail on details that are costly to reproduce: the cabochon, the case profile, and the dial texture. Check these points in order.
- Cabochon: the real crown is set with a blue spinel, faceted and deep. Fakes use glass, resin, or dyed stone that looks flat under light.
- Case diameter: the XL is 42 mm. A "42 mm" replica often measures 40 or 43 mm on calipers.
- Dial: genuine guilloché rings are cut, not printed, and catch light at an angle. Printed or shallow-stamped rings are a clear tell.
- Caseback: engraving on real watches is crisp and consistent. Fake engraving is shallow, uneven, or filled with paint.
- Weight and feel: solid gold XL models feel dense. Gold-plated brass or steel copies feel light, and the plating wears thin at the lugs.
- Movement: a genuine automatic winds smoothly, and its rotor is decorated and signed. Cheap replicas use noisy, undecorated movements.
Why do replica makers get the 42 mm case wrong?
The Ballon Bleu case curves in three dimensions, and its crown guard is machined rather than stamped. Mass-produced copies use generic round shells that look close in photos and wrong in the hand. The sapphire crown cabochon adds cost that budget factories skip, so the crown is the first giveaway.
What should you check before buying a "pre-owned" Ballon Bleu XL?
Ask for sharp photos of the crown, caseback, clasp, and dial edge, then compare them with official images. Request the serial number and a service record, and confirm both with Cartier or an authorized service center. A price far below the market for a steel or gold 42 mm model is the strongest single signal of a counterfeit.
Is buying a fake Ballon Bleu Extra Large legal in the US?
No. Trafficking in counterfeit goods is illegal in the United States, and importing them is prohibited. U.S. Customs and Border Protection can seize shipments, and trademark owners can pursue civil damages and criminal charges. Buyers also get no warranty, no service, and no parts support.
What do fake Ballon Bleu XL watches get wrong on materials?
Solid gold cases are also faked in gold-plated steel or brass, so testing the hallmark matters more than judging the finish. Water resistance claims on replicas are unverified, which puts the movement at risk from moisture. Neither the finish nor the gasket quality holds up the way an authentic case does.
