Short Answer
A fake Cartier Ballon Bleu model 33680 is a counterfeit watch made to imitate a Ballon Bleu case whose back is stamped with the 33680 case code. The dial logo rarely gives it away. The four details that expose most fakes are the crown cabochon, the depth and placement of the case back engraving, the guilloché pattern and printing on the dial, and the movement seen through the display back. Check those first and you will sort real from fake in a few minutes.
What the 33680 Code Actually Means
Cartier Ballon Bleu watches are sold under long reference numbers such as W69012Z4, but each case also carries a shorter stamped code. Sellers on marketplaces and forums often borrow that stamped code and call the watch a "model 33680" because it is the easiest number to read on the back of the case. That is why the same watch can appear under two or three different names, and why the code alone proves nothing. A genuine case back shows the code with the correct font, spacing and depth, and it matches the reference on the paperwork.
How to Spot a Fake Cartier Ballon Bleu 33680 Replica
Four Checks That Expose Most Fakes
- Crown cabochon. The blue stone in the crown should sit flush, catch light evenly, and show no glue line or cloudy edge.
- Case back engraving. Genuine engraving is cut into the metal. Fakes use shallow laser etching that looks grey and feels flat under a fingernail.
- Dial and guilloché. The concentric texture on a Ballon Bleu dial is even and continuous. Copies show a wavy or partly missing pattern near the date window.
- Movement. Look through the display back. Counterfeits often hide a rough rotor, mismatched decoration, or screw heads with chewed slots.
The Crown and Cabochon
The crown of a Ballon Bleu sits under a curved guard, and the blue cabochon inside it is one of the hardest parts to reproduce at low cost. On a fake, the stone tends to look plastic, the blue is either too bright or too dark, and the guard opening is uneven on the left and right. Run a finger along the guard. A genuine case feels smooth and continuous, while a copy often has a sharp lip where the casting was cleaned up by hand.
Case Back and Reference Font
Turn the watch over and compare the stamped code with the reference on the card or receipt. Genuine Cartier engraving is crisp with sharp inner corners, and the sapphire or steel back sits flush in the case. On fakes the code is often the wrong size for the case diameter, letters in the brand name are spaced unevenly, and the screws on the case back do not line up with the surrounding text. Ask the seller for a close photo of the back before you agree to anything.

Dial, Hands and Date Window
Blued steel hands on a genuine Ballon Bleu have a deep, even blue that shifts in light. Copies look painted or purple in direct sun. The date window should be cleanly cut and centred, with a font that matches the numerals on the dial. A common flaw on a fake Cartier Ballon Bleu model 33680 is a date wheel that sits slightly off centre or shows a different typeface from the rest of the dial.
Movement, Weight and Feel
Weight is a rough but useful signal. A genuine steel Ballon Bleu has a solid presence on the wrist, while many copies feel light because the case is thinner and the bracelet uses hollow links. If the watch has a display back, watch the balance wheel for a moment. A steady, even beat with clean finishing around the bridges points to a real movement. Erratic ticking and tool marks point the other way.
Box, Papers and Seller Stories
Boxes and cards are easy to copy, so treat them as a secondary clue rather than proof. Be cautious with sellers who push a fast sale, avoid clear photos of the case back, or explain missing paperwork with a vague story. A short message history that never mentions the 33680 code, the case size, or the movement is a warning sign on its own.
Practical Steps Before You Buy
- Ask for sharp photos of the front, case back, crown and clasp.
- Compare the stamped code with the reference on the paperwork.
- Check the cabochon, engraving depth and dial texture against known images of the same size.
- Request a movement photo if the watch has a display back.
- Pay with a method that offers buyer protection.
When to Get a Second Opinion
If the watch is sold as genuine and the price is high, a professional watchmaker or an authorised service centre can open the case and confirm the movement and case number. That step costs far less than a bad purchase, and it settles the question of a fake Cartier Ballon Bleu model 33680 for good.
