What a fake Portugieser 37mm is
A fake Portugieser 37mm is an unauthorized copy of the IWC Portugieser Automatic 37, a 37 mm stainless steel watch with small seconds at 6 o'clock and a date window at 3 o'clock. Sellers market these copies as "first copy," "1:1," or "super clone." None of those labels come from IWC Schaffhausen. The watch is a counterfeit product, which means it is illegal to import into the United States or to sell here. This guide covers what the copy gets right, where it fails, and the rules that apply.
Why the 37 mm case is hard to copy well
IWC built the Portugieser Automatic 37 for smaller wrists, so the case is proportioned to stay slim and flat. Genuine cases are milled and finished to tight tolerances, then polished and brushed in sections. Most counterfeit cases start as a generic blank that a workshop machines to approximate dimensions. The result is a watch that reads close in a photograph and different in the hand. Case thickness is the usual giveaway. Copies sit tall on the wrist because the movement inside needs more room.

Step-by-step: how to check a Portugieser 37 for replica tells
- Measure the case across the 9 and 3 o'clock points with calipers. A genuine case reads 37.0 mm. Copies often measure 37.5 mm to 39 mm.
- Examine the small seconds subdial at 6 o'clock. Genuine hands are thin and sit level with the dial. Copy hands run thick, and the subdial drops into a deeper recess.
- Study the date window at 3 o'clock. Genuine numerals are sharp and centered. Copy numerals look heavier, and the date disc color seldom matches the dial.
- Inspect the applied numerals and indices with a loupe. Genuine markers are polished with crisp bevels and sharp inside corners. Cast copies show rounded edges and a flat gray finish.
- Check the crown. Genuine crowns carry the Probus Scafusia engraving. Copies show shallow engraving or none, and the tooth count differs.
- Compare caseback engraving. Genuine text is cut deep with even spacing. Copy engraving is shallow, and the reference number frequently does not match the model shown.
- Turn the watch over and view the movement through the display back. Genuine finishing includes Geneva stripes, blued screws, and a signed rotor. Copy movements imitate that look, but the rotor text is printed instead of cut.
Movement tells inside the copy
Most counterfeit Portugieser 37mm watches use a mass-produced automatic movement from a third-party factory. Some sellers describe these as "Swiss ETA" or as a clone of the IWC calibre. The wording is marketing. Ask for a photograph of the movement and compare the bridge layout and screw heads against published images of the genuine calibre. Beat rate, register positions, and power reserve are common mismatch points, and a 28,800 vph sweep does not prove origin on its own.
Legal risk of buying or importing a fake
- Trafficking in counterfeit goods is a federal crime under 18 U.S.C. § 2320, and penalties scale with the number of items.
- U.S. Customs and Border Protection can seize counterfeit shipments and destroy them. The buyer has no recourse and no refund.
- IWC and its authorized service centers will not service, repair, or authenticate a counterfeit watch.
- Resale value sits near zero outside the counterfeit market.
Questions buyers ask
Does a "Swiss Made" marking prove a Portugieser 37 is genuine?
No. Copy dials carry the same stamps with no oversight behind them. Authenticity comes from service records and an inspection by an authorized watchmaker, not from a dial print.
Fake Portugieser 37mm: Best Legal Alternatives to the Look
Can a local watchmaker service a fake Portugieser 37mm?
Some independent shops will clean and regulate a generic automatic movement. Many decline once they identify the watch as counterfeit. Parts availability is the reason most of them give.
Is a "first copy" the same as a super clone?
Both are seller terms with no fixed definition. The same factory output can be listed under either label at two different prices.
