What a fake IWC Portugieser is
A fake IWC Portugieser is a watch built to look like an IWC Portugieser but made by a third party. It carries the IWC name, logo, and reference numbers without a license from IWC. IWC is owned by Richemont. The Portugieser line traces to 1939, when IWC built a large wristwatch with a pocket-watch movement for two Portuguese dealers.
Copies range from about $50 quartz pieces to $800 builds sold as "super clones." A genuine steel Portugieser Automatic 40 lists near $7,000 to $8,000 in the US.
Models that get copied most
- Portugieser Automatic 40, ref IW3583, caliber 82200
- Portugieser Chronograph 41, ref IW3716, caliber 69355
- Portugieser Automatic 42, ref IW5007, caliber 52010
- Portugieser Perpetual Calendar, ref IW5033, caliber 52615
The Chronograph 41 and Automatic 40 are the common targets. The Perpetual Calendar costs more to copy, so copies of it are rarer and often crude.
Points to check
Case and caseback
Genuine cases come in steel, red gold, white gold, or platinum. Caseback engraving on the real watch is crisp and shallow with even lettering. Fakes show soft or doubled text, wrong reference numbers, or a display back where the real reference has a solid one.
Dial and hands
The Portugieser dial has applied numerals, a railroad minute track, and leaf-shaped hands. Copies print the numerals instead of applying them, or set the track too close to the chapter ring. Date fonts differ. A real date wheel uses a flat, thin numeral.
Movement
Real in-house calibers have Geneva stripes, blued screws, and a signed rotor. Copies use Seagull ST19, ETA 2824 clones, or quartz. Winding feel and sweep rate differ. A 28,800 vph movement ticks 8 times per second. A 21,600 vph copy ticks 6 times per second.
Strap and clasp
IWC ships these references on alligator or rubber. Stitching is even. Fakes use embossed leather or PU with uneven stitches and a stamped buckle.
Legal status in the US
Importing, selling, or trafficking counterfeit watches is a federal crime under 18 U.S.C. § 2320. US Customs and Border Protection seizes counterfeit goods at ports of entry. Trademark holders can sue sellers under the Lanham Act for statutory damages.
