Short answer
The best fake Portugieser Automatic is the one that matches a real reference first. Most copies target the 42.3 mm Portugieser Automatic (ref. IW500x, calibre 52010) or the 40.4 mm Portugieser Automatic 40 (ref. IW3583, calibre 82200). Copies of the 40.4 mm model track closer to the original case shape. Copies of the 7-day model fail on the power reserve. Check the reference number, then the movement, then the dial print. A seller who lists no reference number is a seller to skip.
References to know
- Portugieser Automatic 42.3 mm: calibre 52010, twin barrels, 168-hour power reserve, Pellaton winding, 28,800 vph (4 Hz).
- Portugieser Automatic 40.4 mm: calibre 82200, 60-hour power reserve, 28,800 vph.
- Portugieser Chronograph 41 mm: calibre 69355, two subdials at 12 and 6.
Case size differs by 2 mm between the two automatics. A 42 mm copy sold as a 40 mm watch is a mismatch, and the dial proportions show it. Subdial spacing on the 40 mm sits wider than on the 42 mm.
Movement checks
The genuine calibre 52010 runs 7 days on a full wind. No copy at hobbyist prices does. In most replicas the power reserve subdial at 3 o'clock is painted or driven by a separate gear that does not track the mainspring. Wind the watch, set it down, and watch the indicator over 48 hours. If the needle does not move with the actual reserve, the function is cosmetic.
Finish is the second tell. The real movement shows Geneva stripes, blued screws, and an engraved rotor. Copies show stamped bridges, painted screw slots, and a rotor with shallow laser engraving. Photographs hide this. Ask for a macro shot under direct light.
Dial and case checks
- Numerals: applied and raised on the original, flat and glued on weak copies.
- Print: IWC lettering and SCHAFFHAUSEN spacing sit tight and thin. Copies show wide tracking and heavier strokes.
- Hands: leaf-shaped, faceted, with a clean center ridge. Copies show flat hands with rounded edges.
- Caseback: sapphire display, deep engraving, crisp reference and serial numbers. Etched numbers on copies sit shallow.
- Crown: signed, with sharp fluting. Copies show soft fluting and an off-center logo.
Price bands
Replica pricing runs about 250 to 1,200 USD. Above 700 USD you should get a 28,800 vph automatic, a working power reserve, and a sapphire crystal. Below 400 USD you usually get a 21,600 vph movement and printed subdials. The steel Portugieser Automatic retails above 13,000 USD, so any claim of "same parts" at 500 USD is false.
Legal limits in the US
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. § 2320. A first offense carries up to 10 years in prison and a 2,000,000 USD fine for an individual. US Customs and Border Protection seizes counterfeit watches at the border. Buying for personal use carries lower risk than resale, but the item can still be seized. Treat any purchase as a legal risk, not a gray area.
What to ask a seller
- Which reference does this copy?
- What is the movement, beat rate, and jewel count?
- Does the power reserve subdial move with the mainspring?
- Case diameter in millimeters, measured with calipers?
- Macro photos of the dial print, crown, and caseback?
