The short answer: a fake Portugieser Automatic 42 is a counterfeit copy of IWC's 42.3 mm Portugieser Automatic, and the choice that matters most is not which seller you pick but whether you accept the risks that come with it. US customs can seize and destroy the shipment, no replica movement delivers the genuine seven-day power reserve, and many of the listings you will find are the same factory watch resold with different studio photos. If you decide to continue, judge the piece on movement type, case finishing, dial printing, and how the seller answers direct questions, not on the photos on the landing page.

The Genuine Reference You Are Comparing Against

IWC builds the Portugieser Automatic in a 42.3 mm case, about 14 mm thick, with the in-house 52010 calibre and a twin-barrel system rated at seven days of running time. The dial has applied indices, a railroad-style minute track, a small seconds subdial at 9 o'clock, and a power reserve indicator at 3 o'clock. Lug width is 22 mm. Knowing these numbers gives you a checklist, because every specification the counterfeit skips is a place where corners were cut somewhere else too.

Legal and Practical Risk in the US

Counterfeit watches are illegal to import into the United States. Under 19 U.S.C. 1526, goods bearing a counterfeit trademark are subject to seizure and destruction, and the buyer has no recourse when a parcel is stopped. That means a seller who promises reshipment is promising something they cannot always deliver. Beyond customs, the payment side carries risk: wire transfers and crypto leave you with no chargeback path, and card payments to unfamiliar processors can expose your details. Treat every purchase as money you can lose.

The Quality Tiers You Will Actually See

• Entry tier: mineral or basic sapphire glass, a Miyota 8215 or similar workhorse movement, stamped dial furniture, and a case with soft edges. Runs at 21,600 vph and often has a rotor that does not match the genuine engraving.
• Mid tier: sapphire crystal with anti-reflective coating, an Asian 7750 derivative or a decorated automatic at 28,800 vph, better brushing and polishing on the case, and a dial with printed rather than stamped markers.
• Top tier: custom movement plates that imitate the 52010 layout, hand-finished bridges, correct dial proportions, a power reserve near 40 hours rather than the claimed 168, and a bracelet or strap with proper stitching and hardware.

No tier matches the genuine watch, and no tier carries a real seven-day reserve. Claimed reserves of 168 hours on a replica are marketing copy.

What to Look For in a Listing

• Movement photos that show the actual watch, not a stock image from a catalog.
• A stated case diameter close to 42.3 mm. Anything listed as 40 mm or 44 mm is a different watch with a familiar name attached.
• Clear photos of the caseback, crown, and clasp. Blurry images usually hide poor finishing.
• Ordering terms written down: payment methods, what happens if the parcel is held, and whether returns exist at all.
• A seller who answers specification questions with numbers instead of reassurance.

Parameter Bands Worth Verifying

• Case diameter: 42 to 42.5 mm. Outside this band, the proportions of the dial and lugs will look wrong on the wrist.
• Thickness: 13.5 to 14.5 mm. Thin replicas usually mean a smaller movement inside a case that was not built for it.
• Lug width: 22 mm, so standard straps fit without adapters.
• Crystal: sapphire with visible anti-reflective tint. Mineral glass scratches within months.
• Water resistance: treat any claim as untested. Gaskets on replicas are rarely pressure-checked, so keep the watch away from pools and showers.
• Beat rate: 28,800 vph for the smooth sweep buyers expect. 21,600 vph is a tell.

Pitfalls That Cost Buyers the Most

• Paying by wire or crypto to a seller with no history. Funds sent this way rarely come back.
• Trusting review pages that host their own ads. The reviews and the store are often the same business.
• Buying during a holiday rush, when parcels sit in customs queues longer and seizure odds rise.
• Assuming a high price equals high quality. Price and tier do not track as closely as sellers suggest.
• Ignoring service reality. Many watchmakers will not touch a counterfeit, so a broken movement can mean a lost watch.

FAQ

Is a replica Portugieser Automatic 42 waterproof?

Assume it is not. Cases are assembled without pressure testing, and gaskets are the cheapest part in the build. Splash resistance is the realistic limit.

Why does the power reserve never match seven days?

The genuine seven-day reserve comes from a twin-barrel in-house calibre. Replicas use standard movements with roughly 38 to 45 hours, and the power reserve indicator is often decorative rather than functional.

Can it be shipped to the United States?

It can be shipped, but it can also be seized. Counterfeit goods are subject to customs detention and destruction, and the loss falls on the buyer unless the seller states otherwise in writing.

What should I ask a seller before paying?

Ask for the movement type, measured case diameter and thickness, crystal material, current photos with a timestamp, and the exact policy if the parcel is stopped. Vague answers are your signal to walk away.
