A fake Blancpain 5200-0113-52A watch is a counterfeit copy of the Fifty Fathoms Bathyscaphe Flyback Chronograph, a 43.6 mm ceramic dive watch that Blancpain sells for a five-figure price. The genuine watch runs an in-house F385 column-wheel chronograph movement and ships with a numbered certificate and warranty card. Counterfeits copy the case shape and the dial text, then stop there.
What is the Blancpain 5200-0113-52A?
Reference 5200-0113-52A belongs to the Fifty Fathoms Bathyscaphe line, Blancpain's modern dive collection. The 5200 prefix marks the flyback chronograph model: a 43.6 mm case, a ceramic bezel insert, and 300 m of water resistance. The characters after the dash code case material, dial, and strap, so the full string points to one exact configuration.
The engine is Blancpain's caliber F385, a flyback chronograph with a column wheel and a vertical clutch. A sapphire caseback shows that movement, which makes the back of the watch as important as the dial when you judge authenticity.
Why the reference number in a listing proves nothing
Any seller can type "5200-0113-52A" into a product title. The string is public, short, and copied straight from Blancpain's catalog. Use the number to confirm which watch you are looking at, then verify the watch itself.
How do fake 5200-0113-52A watches reach buyers?
Counterfeit production splits into three rough tiers, and the price tracks the tier.
Low-grade copies
These sell for under $150. The case is steel with black coating, the glass is mineral, and the chronograph is a cheap quartz module with glued-on subdials. Caseback text is printed at shallow depth, and the fonts do not match Blancpain's.
Mid-tier replicas
Prices run $300 to $800. These use a Chinese automatic chronograph or a copy of an ETA 7750, a sapphire crystal, and a coated steel case that imitates ceramic. Subdial spacing and the date window give them away, because the movement inside sits at a different size than the F385.
Super clone copies
The top tier sells for $1,000 and up and copies case geometry from photos. Some use real ceramic bezels and sapphire on both sides. The movement remains the weak point. No Chinese factory builds a working F385 clone with a column wheel and a vertical clutch.
How do you tell a fake from a real one?
Start with the movement and work outward. A watchmaker with a caseback tool settles the question in minutes.
- Movement: The F385 has a column wheel, a vertical clutch, and finishing that no replica matches. Look for the Blancpain engraving, the jewel count, and the shape of the chronograph bridge.
- Case material: Real Bathyscaphe cases are ceramic, not coated steel. Ceramic feels lighter and stays cool, and it does not chip into bright metal at the edges.
- Bezel: The genuine insert aligns with the 12 o'clock marker, turns with firm clicks, and shows no gap between insert and case.
- Dial: Check the printed text under a loupe. Fakes show thick serifs, uneven spacing, and lume that glows a different color from the hands.
- Caseback: Engraving on a real watch is deep and crisp, with a serial number that matches the paperwork.
- Papers and box: A genuine set includes a numbered certificate, a warranty card, and a Blancpain box with the correct reference on the label.
- Price: Any offer far below used market value is a copy or a stolen watch.
What should you check in seller photos?
Online listings for this reference live or die on photos, and fakes hide in them.
- Ask for a shot of the movement through the caseback with the rotor turned to a position that is not in the catalog image.
- Ask for a photo of the warranty card next to the caseback serial. A real seller can produce both.
- Study the crown guards and the case flank. Copies soften these lines.
- Request a short video of the chronograph start, stop, and reset. A flyback movement snaps back. A cheap module stutters.
- Compare the hands against a reference photo. Replica hand sets come from a catalog, not from a case-matched batch.
Replica, fake, homage: what is the difference?
An homage borrows a style but puts its own brand on the dial, which is legal. A fake or replica copies the brand name, logo, and reference number, which is trademark infringement. Sellers use "replica" to soften the word, but the legal position does not change.
What are the risks of buying a counterfeit?
Counterfeit watches carry legal and practical costs that buyers learn about after payment clears.
- Customs can seize the parcel. Importing counterfeit goods into the United States is illegal, and CBP destroys seized items without refunding the buyer.
- There is no warranty and no service path. Authorized Blancpain centers refuse to work on counterfeits.
- Water resistance claims are unverified. A fake rated for 300 m can leak in a shower and ruin the movement.
- Resale value is zero. No dealer or auction house will touch it.
How do you verify a genuine 5200-0113-52A?
Buy from an authorized Blancpain dealer or a seller with documented service history. Ask for the serial number and confirm it with a Blancpain boutique or service center. Then have an independent watchmaker inspect the movement before the return window closes. If a seller refuses any of those steps, walk away.
FAQ
Can a super clone Blancpain fool a watchmaker?
No. The caseback is sapphire on this reference, so the movement stays visible. Movement architecture, finishing, and engraving separate a genuine F385 from any copy in seconds.
Does 5200-0113-52A appear on counterfeit listings?
Yes. Fake listings reuse real reference strings because buyers search for them, sometimes with a space or without the dashes. A matching number in a title tells you nothing about the watch behind it.
Is it legal to own a fake watch in the US?
Owning a counterfeit is not the main legal risk. Importing, selling, or shipping one across borders is, and CBP can seize the item at the port.
