Short answer
The IWC Portugieser Hand-Wound 37 is a 37 mm watch with a hand-wound movement and a small seconds subdial at 6 o'clock. Replica versions copy reference IW3201: case size, dial layout, leaf hands, and a display back. Build quality splits into tiers. Entry replicas use plated cases and automatic movements that do not match the genuine watch. Mid and top tiers use 316L stainless steel, sapphire glass, and a hand-wound movement. No replica is a genuine IWC, and no replica carries IWC warranty or service.
Genuine specs to compare against

- Case diameter: 37 mm
- Case height: about 9 mm
- Movement: IWC calibre 82200, hand-wound, in-house

These numbers come from IWC product data. If a seller lists a 40 mm case or an automatic movement, the watch is a different model or a mismatched build.
Movement: the first check
The genuine watch winds by hand. There is no rotor. A replica with an automatic movement and a spinning weight behind the display back is a visible mismatch. Some sellers hide the movement or blur the caseback photo. Ask for a clear image of the movement through the caseback. A hand-wound copy shows a ratchet wheel, a barrel, and no oscillating weight. Winding feel matters too: 20 to 30 turns from empty should bring the watch to full power.
Case and thickness
37 mm is small for a modern watch. Some replicas start from a 40 mm or 42 mm case and print 37 in the listing. Measure the outside of the case without the crown. Thickness is the second tell. A build much over 10 mm sits high on the wrist and catches a shirt cuff, which is the point of this model.
Dial and hands
Check four items:
- Subdial position: centered at 6 o'clock, not shifted left or right
- Printing: sharp edges on the numerals and on the IWC and SCHAFFHAUSEN text
- Hands: leaf shape, matching length on the hour and minute hands
- Crystal: sapphire with anti-reflective coating. Mineral glass scratches.
Price tiers
Rough street prices for this model:
- Under $150: plated brass case, mineral glass, automatic movement, wrong thickness.
- $200 to $400: 316L steel, sapphire glass, hand-wound movement, close dial work.
- $450 and up: better bridge finishing, correct crown profile, closer strap hardware.
Prices move with the seller. A listing without movement photos carries risk.
Legal status in the US
Counterfeit watches are illegal to import, sell, or traffic in the United States. 18 U.S.C. § 2320 covers trafficking in counterfeit goods, and trademark holders can file civil claims. US Customs can seize shipments. A replica is a copy, not a gray-market watch and not a pre-owned genuine watch.
