Fake IW371778 means a counterfeit watch built to look like the IWC reference IW371778. The genuine watch leaves IWC Schaffhausen with its own movement, a machine-engraved caseback, and a serial number that matches factory records. A fake copies the outside, runs a clone or generic movement, and carries no manufacturer support.
Counterfeit IW371778 watches sell for $80 to $700 through the same channels that move fake Rolex watches. Both markets share factories, parts suppliers, and shipping routes, which is why the tells overlap.
What is reference IW371778?
IW371778 sits in IWC's chronograph output, the same family that includes the Portugieser Chronograph line. The reference points to a stainless steel case, a chronograph function, and a sapphire crystal.
Exact specs (case diameter, dial variant, movement calibre) belong on IWC's own product page or with an authorized dealer. IWC revises details between production runs, so two watches sharing one reference number can differ.
Why counterfeiters pick this reference
- Steel cases cost less to copy than gold ones, so the margin stays wide.
- The dial design uses applied markers and printed text, both cheap to reproduce.
- IWC sells fewer units than Rolex, so most buyers never handle a real one.
- The genuine watch has waiting lists in several markets, which pushes impatient buyers toward copies.
How to spot a fake IW371778
Case and finish
Run a fingernail along the case edges. A real IWC case has crisp bevels, even brushing, and a polish that stops at the line. Fakes show rounded edges, tool marks, or polish that bleeds onto brushed surfaces.
Dial and printing
Check the dial text under 10x magnification. Genuine IWC printing has sharp edges and even stroke weight across every letter. Fake dials show blurry type, uneven spacing, and lume that sits proud of the dial instead of flush.
Crystal and hands
A real sapphire crystal throws a faint blue or clear reflection and resists a key scratch. Fakes use mineral glass that scratches with light pressure. Hand finishing also gives it away: real hands have polished bevels, fakes look flat and dull.
Movement
Ask for a photo of the movement through the caseback before money changes hands. Fakes run Chinese automatic chronograph movements, most based on the Valjoux 7750 layout, with wrong or missing engravings. IWC's own calibres show specific finishing patterns, and the rotor engraving matches the calibre number printed on the caseback.
Caseback and serial number
The serial should match the reference and appear in IWC's service records. Sellers of fakes reuse one serial across dozens of listings, so run a search on the number before you buy. Genuine casebacks carry deep, machine-cut engraving. Fakes use shallow laser etching that catches light in a flat way.
Box, papers, and history
A real set includes a warranty card with a dealer stamp, matching serials, a manual, and a fitted box. Fake sets use photocopied cards and boxes with the wrong font or weight. Call the dealer named on the card to confirm the sale happened.
Price tiers of counterfeit IW371778 watches
- $80 to $150: quartz or low-grade automatic, mineral glass, wrong case size, tinny pushers.
- $200 to $400: mid-tier clone with sapphire glass and a passable dial, still a cheap movement.
- $500 to $700: the "super clone" tier, with a copied case, decorated movement, and a convincing box.
- Above $900: sellers claim Swiss parts and Swiss assembly. Ask for proof, because the claim rarely holds.
Price tracks the outside of the watch, not the inside. Two fakes at different prices can share the same movement and differ only in dial printing and case finishing.
What movement sits inside a fake IW371778?
Most fakes run a Chinese-made automatic chronograph movement built on the 7750 layout. The pushers feel spongy, the rotor spins loud, and the power reserve falls short of the real watch. A small number use a copied in-house design that still misses IWC's accuracy specs and cannot be serviced by IWC.
Fake vs genuine: quick comparison
- Case finishing: crisp bevels and clean brush lines against rounded edges and bleed.
- Dial text: sharp type against blurry or uneven printing.
- Movement: IWC calibre with matching rotor engraving against a generic clone.
- Serial: traceable in IWC records against a number repeated across listings.
- Service: IWC service centers accept the real watch. Nobody services the fake.
Legal and practical risks
- Importing a counterfeit violates customs law in the US and the EU. Shipments get seized and destroyed, and you lose the money.
- Selling a fake as genuine is trademark infringement and fraud, both of which carry civil and criminal penalties.
- No authorized service center will touch a counterfeit. Independent shops that do charge more than the watch cost.
- Water resistance is untested on fakes. A swim or a shower can ruin the movement.
- Resale value is close to zero. Nobody pays real money for a used fake.
Is a fake IW371778 worth buying?
For a costume or a photo shoot, a low-tier fake costs less than a night out and does the job. For daily wear, the math changes. A fake will not keep time like a real chronograph, will not survive a service, and will not hold value, while a mid-range Seiko or Tissot at the same price does all three.
How to verify a genuine IW371778 before you buy
- Photograph the caseback and serial, then send the images to IWC customer service for a record check.
- Ask for the original purchase receipt and the name of the dealer who sold it.
- Meet a watchmaker who can open the case and inspect the movement before you pay.
- Compare the watch against IWC's official product page, not a marketplace listing.
- Pay with a method that allows a chargeback if the watch turns out to be fake.
FAQ
Does every fake IW371778 share the same flaws?
No. Flaw lists change as factories update tooling and dial suppliers. Treat any published tell as a starting point, then inspect the individual watch in front of you.
Can a watchmaker spot a fake without opening the case?
Sometimes. Dial printing, case finishing, and crystal reflections give strong clues from the outside. Opening the case and reading the movement gives a firm answer in most cases.
How much does a real IW371778 cost?
Check IWC and authorized dealers for current retail pricing. Used examples move with condition, completeness of the box and papers, and service history, so two watches with the same reference can sell at very different numbers.
Where do fake IW371778 watches show up?
Social media sellers, classified apps, and pop-up sites that vanish after payment. Listings that hide the serial, refuse movement photos, or push a wire transfer carry the highest risk.
