If you are searching for a fake IW371768, start with the blunt version: a counterfeit is not a discounted version of the same watch. The IW371768 sits in IWC's Portugieser Chronograph family, and a replica of it will have a different movement, different internals, no manufacturer warranty, no service path, and no resale market. Add the risk of a customs seizure and the total cost of a cheap fake is often higher than the price gap suggests. The smarter purchase is a documented genuine example, and the rest of this guide covers how to tell one from the other.

What the IW371768 reference actually is

The IW371768 belongs to the Portugieser Chronograph line, the round-cased, clean-dialed chronograph IWC has built across several generations. The family signature is easy to describe and hard to reproduce well: a slim bezel, applied Arabic numerals, leaf-shaped hands, a finely printed minute track, and two vertically stacked subdials. Current-generation examples run about 41 mm across and roughly 13 mm thick, with sapphire crystal front and back on most versions and a chronograph movement from the 69000-series family. Specifications shift between generations, so confirm the exact numbers for your reference on IWC's own product page before you compare anything.

Why counterfeit listings are a bad buy

• Legality: Counterfeiting infringes registered trademarks and is illegal in the United States. Buying is not a neutral act when the item is seized in transit.
• Seizure and loss: Shipments of counterfeit watches get stopped by customs. You can lose both the watch and the money, with no realistic recourse against an overseas seller.
• No service: IWC and most independent watchmakers will not touch a counterfeit. When the movement fails, you own a paperweight.
• No resale: Replica watches have no secondary market outside the same gray channels that sold it to you.
• Materials: Plating wears through, gaskets fail, and water resistance claims on replicas are marketing copy, not engineering.

How to check a genuine IW371768 before you pay

Case, dial, and finish

Examine the printing under magnification. Genuine dial text is crisp and level, with consistent stroke weight on the Schaffhausen line. Check that the subdial hands are the right shape and length, that the numeral appliques sit flat, and that the case flanks have sharp, even brushing with polished bevels that catch light in one continuous line. Replica cases often show soft edges and uneven gaps at the lugs.

Movement and caseback

Open the caseback or ask for photos of the movement through the display back. A genuine column-wheel chronograph shows a finished bridge layout with correct engraving, and the rotor and bridges match the reference. Counterfeit movements are frequently modified third-party calibres with wrong engraving, a wrong jewel count, or a pusher feel that is gritty rather than crisp.

Serial, paperwork, and provenance

Match the serial on the caseback to the warranty card or extract. Ask for the original purchase receipt, service history, and box. Verify the seller's identity and use a payment method with buyer protection. For any high-value purchase, budget for an independent authentication by a watchmaker who handles IWC.

Common pitfalls

Stock photos instead of images of the actual watch. Sellers who insist on bank transfer or crypto. Listings that mix reference numbers or show a different dial than the one described. Customs insurance offers that cannot be enforced. A price far below the current market for a documented example, which is the oldest signal there is.

FAQ

Is a super clone IW371768 identical to the real watch?

No. It can look similar in photographs and still differ in movement, materials, tolerances, and finishing. Photographs hide the details that authentication depends on.

Can a watchmaker tell the difference?

Yes, in most cases, and quickly. Movement architecture, caseback engraving, dial printing, and pusher feel are all hard to reproduce at cost.

What happens if customs seizes a counterfeit watch?

The shipment can be detained and destroyed, and you are unlikely to recover what you paid. That is a real cost, not a hypothetical one.

Will IWC service a counterfeit?

No. Manufacturer service centers work on genuine products, and independent watchmakers may decline for parts and liability reasons.
