Core Buying Advice
A fake Swiss Fifty Fathoms Bathyscaphe 5200 copies the Blancpain Bathyscaphe ref. 5200, and no replica reproduces its engineering. The genuine watch runs Blancpain's in-house caliber 1315 with three series-coupled barrels, a 120-hour power reserve, and a 300 m depth rating in a 43 mm case. Replica versions use third-party movements, thinner cases, and seals that nobody has tested. Decide first that you are buying a look-alike with unknown internals, and only then compare sellers. If the pitch leans on the words Swiss, 1:1, or identical, that pitch is the product.
Cheap Fifty Fathoms Bathyscaphe 5200: Real Options vs Fakes
What to Look For
Case and profile
Ask for measured thickness, not claimed thickness. The genuine case sits near 13.6 mm tall, and many replicas land at 12 mm or push past 15 mm. A caseback that sits proud, crown guards that look poured rather than machined, and a bezel that rises above the crystal line are all tells. Lug width on the 5200 is 23 mm, so confirm the strap or bracelet fits with no gap.
How to Find a Discounted Fifty Fathoms Bathyscaphe 5200
Movement
Most replicas carry an Asian 2824 or 2836 clone, or a Japanese NH35. Some listings claim a clone of the 1315. That clone has the wrong bridge layout and a power reserve near 40 hours instead of 120. Ask for a photo of the movement through the caseback and a timing reading on a timegrapher. Anything a seller will not photograph, the seller does not want you to see.

Dial, bezel, and crystal
Check date font and window position, lume color against a reference photo, and whether the bezel insert is ceramic or printed aluminum. Sapphire with anti-reflective coating on both faces is the standard to hold. Mineral glass scratches and reads flat under light.

Water resistance
Assume no rating. A 300 m claim on a replica means a gasket exists. Do not swim and do not dive, whatever the listing says. If you need a diver, buy a watch that carries a real warranty.
Parameter Bands
- Case diameter: 40 to 44 mm claimed, against 43 mm on the genuine 5200
- Case thickness: 12 to 15.5 mm, against roughly 13.6 mm on the reference
- Lug width: 23 mm
- Movement: NH35, Asian 2824 or 2836 clone, or a labeled 1315 clone
- Power reserve: 36 to 45 hours in practice, against 120 hours genuine
- Crystal: sapphire with double AR coating preferred, mineral glass common at the low end
- Water resistance: unverified, so treat every claim as marketing copy
Pitfalls That Cost Buyers Money
- Swiss made printing on a replica case says nothing about the parts inside it.
- Photos get borrowed between sellers. Reverse-check any image set before paying.
- Bank wire and crypto leave you with no chargeback route when the watch arrives wrong.
- Customs can seize counterfeit shipments, and the loss falls on the buyer.
- Few watchmakers service replica movements. Plan for replacement, not repair.
- Screwed casebacks often arrive cross-threaded or over-tightened from the factory.
FAQ
Is buying a counterfeit watch legal in the US?
Importing counterfeit goods is prohibited. U.S. Customs and Border Protection can seize a shipment, and the buyer has no recourse for the money spent.
Does any replica contain a real Blancpain movement?
No. Blancpain does not sell the caliber 1315 as a loose part to third parties, so a genuine movement claim in a replica listing is false.
Can a replica pass as the real thing?
Not to a dealer and not to a service center. Passing one off in a sale becomes counterfeiting and fraud, which carries criminal exposure.
What should I check first on arrival?
Bezel alignment, crown threading, date change at midnight, and timegrapher rate. Document all of it before you wear the watch.
