The term fake Blancpain 5050-11A0-52B describes a counterfeit watch that copies the reference number of a genuine Blancpain model. The reference 5050-11A0-52B belongs to Blancpain, not to the counterfeiters, so the word fake applies to the copy that carries it. Because buyers search by reference number, counterfeit sellers print real numbers on boxes, hangtags, and casebacks, which is why an exact reference in a listing proves nothing on its own.
What the 5050-11A0-52B reference identifies
Blancpain groups reference numbers in blocks. The 50xx range covers the Fifty Fathoms family, the brand's dive watch line, which includes the Bathyscaphe models. Inside a full reference, the trailing groups encode case material, dial variant, and the strap or bracelet fitted at the factory. A genuine 5050-11A0-52B is therefore a specific combination of case, dial, and strap rather than a generic model name.
That detail matters when you compare watches. Two authentic Blancpain divers from the same base model can carry different full references because of a strap change alone. A counterfeit operation only needs one real reference to reproduce it across a production run, so the same number ends up on thousands of copies with identical packaging.
Why counterfeit listings reuse exact reference numbers
- Reference numbers are how collectors and search engines identify a watch.
- A real number makes a listing harder to dismiss at a glance.
- Buyers comparing a copy against reference photos may miss small differences.
- The number travels onto the box, the card, and the caseback, so the set looks complete.
How to tell a counterfeit from a genuine watch
Case, bezel, and finish
Genuine Blancpain cases are machined to tight tolerances, with crisp edges, even brushing, and a clean line where polished surfaces meet brushed ones. Counterfeits tend to show soft or rounded edges, uneven polishing, and a bezel that turns with play or grit.
Dial printing and hands
Study the dial under magnification. Authentic printing is sharp and consistent, with markers sitting level. Copies usually show thicker text, uneven spacing, dust under the crystal, and hands with rough edges or lume that does not match the dial.
Movement, caseback, and serial
Blancpain fits in-house movements with finishing that is visible through a display back. A counterfeit often hides a third-party movement behind a solid back or a poorly engraved rotor. Serial and reference engravings should be clean and consistent with the model, not shallow or misaligned.
Papers, box, and service history
A complete set helps, but it is not proof, because counterfeiters print cards and boxes as well. Confirm the reference and serial with Blancpain or an authorized service center, and ask to see service records.
Price and service reality
Genuine Blancpain Fifty Fathoms watches trade in the thousands of US dollars, and authorized service is part of ownership. An offer far below that range is the strongest signal of a counterfeit. Copies also come with no warranty, no parts support, and no realistic resale value.
Legal and safety considerations
Counterfeit watches infringe trademarks, and shipments can be seized at the border. Beyond the legal side, a copy's claimed water resistance is not verified, so wearing one in water risks damage to the movement. A buyer also has no recourse if the watch arrives broken or stops running.
Quick checklist before you buy
- Verify the full reference against Blancpain's published collection.
- Confirm the serial with an authorized dealer or service center.
- Inspect finishing at the lugs, the bezel edge, and the dial printing.
- Treat any price far below market as a counterfeit signal.
- Skip sellers who will not show movement photos or a return policy.
In short, 5050-11A0-52B is a real Blancpain reference, and a watch sold as a fake version of it is a counterfeit borrowing that number. Authenticate the actual watch in front of you instead of trusting the reference printed in a listing.
