The honest answer about a cheap 5200
Search for a cheap Blancpain Fifty Fathoms Bathyscaphe 5200 and nearly every result is a counterfeit. That is the real starting point. The genuine reference sits in the five-figure range and holds value on the secondary market, so a watch selling for a few hundred dollars is a copy with a printed logo. In the US and most of Europe, buying one is trademark infringement, and Customs can seize the parcel before it reaches you with no refund and no appeal. I would rather spend your attention on two things that actually work: recognizing the fakes, and legitimate divers that deliver a similar look for real money.
Learn the real watch before you compare anything
The Bathyscaphe 5200 uses a 43.6mm case in ceramic or titanium, an in-house caliber 1315, and 300m of water resistance. That movement matters most when you are checking authenticity. It carries three series-coupled barrels for a 120-hour power reserve, a silicon balance spring, and it beats at 3Hz, or 21,600 vibrations per hour. Most counterfeit movements run at 4Hz, so a slow, slightly lazy sweep on a supposed 1315 is a strong tell.

Quick checks that expose a copy
- Beat rate. Time the sweep or ask for a timegrapher photo. 28,800 vph on a Bathyscaphe is wrong.
- Date position and font. Fakes often sit the window a fraction off center with thin, mismatched numerals.
- Bezel insert. Genuine ceramic has a matte depth and a properly seated lume pip at 12.
- Caseback engraving. Laser etching looks shallow and gray; the real thing is crisp and deep.
- Heft and crown action. Titanium feels light but the threads are buttery, not gritty.
- Dial text. Look at letter spacing on the logo. Copies crowd it or stretch it.
Legit divers that scratch the same itch
You want a ceramic bezel, sapphire crystal, decent water resistance, and a case that reads well on a strap. Plenty of brands do this without pretending to be Blancpain.
- Christopher Ward C60 Trident Pro 300. Swiss movement, 300m, clean dial, strong value.
- Baltic Aquascaphe. Vintage diver proportions, sapphire, great on a tropic strap.
- Seiko SPB453 or SPB143. 200m, in-house 6R movement, the default pick under a grand.
- Oris Divers Sixty-Five. Bronze or steel, domed sapphire, real heritage.
- Certina DS Action Diver. 300m and a Swiss automatic for mid-hundreds.
- Longines HydroConquest. A step up in finishing if your budget stretches.
- Tudor Black Bay 58, pre-owned. The closest thing to Bathyscaphe feel at a fraction of the price.
If you are buying genuine, check these parameters
Confirm the reference on the caseback, ask for the service history, and insist on the full set with box and papers. A 1315 service is not cheap, so a documented service within the last five years is worth paying for. On grey market and auction platforms, 5200 listings cluster in the five-figure range. Anything dramatically below that is a warning, not a bargain. Ask about the return window in writing before you send money, and pay in a way that gives you a dispute path.
Pitfalls that cost people money
- Listings that use words like 1:1, super clone, or mirror quality. Those are counterfeits by definition.
- Watches that claim Swiss made at a price no Swiss automatic can hit.
- No service path. Independent watchmakers cannot order 1315 components for a fake, and no brand will touch it.
- Resale value of zero. Counterfeits are not collectible and not liquid.
- Import seizure. You lose the watch and the money, and the seller will not answer.
- Warranty promises from storefronts that disappear in a year.
Set a budget, pick a real watch that fits it, and buy from someone who will still exist when you need a service. That route costs more upfront and far less over ten years.
