The fake Portugieser hand wound 37 is a counterfeit built to look like IWC's Portugieser dress watch in a 37 mm case with a manual-wind movement. No such reference exists. IWC sells the 37 mm Portugieser Automatic, while its hand-wound Portugieser models are much larger, so any listing that pairs 37 mm with hand winding is describing a replica, not a catalog watch.
Is there a real IWC Portugieser Hand-Wound 37?
No. The hand-wound Portugieser family, sold as the Hand-Wound 8 Days, uses a 45 mm case with an in-house eight-day movement. IWC's 37 mm Portugieser case is offered only with automatic movements. That mismatch is the clearest tell in any advertisement using this keyword.
How does the fake Portugieser hand wound 37 differ from the real watch?
Replica makers take the 37 mm Portugieser Automatic silhouette and fit a generic manual movement, which changes the proportions. The result looks close in photos and wrong on the wrist.
- Case: replicas typically measure 38 to 39 mm wide and sit 1 to 2 mm thicker than the genuine 37 mm case.
- Movement: unbranded manual-wind calibers with stamped bridges, no Geneva stripes, no blued screws, no perlage.
- Dial: flat-looking applied numerals, uneven sub-seconds printing, and font weights that drift from the original.
- Crystal: domed sapphire without the double anti-reflective coating, so it mirrors light instead of going nearly invisible.
- Caseback: laser-etched reference and serial numbers that do not match IWC records, often on a back style the model never used.
How can you tell a counterfeit Portugieser from a genuine one?
Start with the movement. A genuine Portugieser hand-wound caliber shows hand-finished bridges, polished bevels, and a long, smooth winding action with a defined stop. Counterfeits feel gritty and overwind without resistance. Then check the details: crisp pad-printed dial text, a case that measures exactly as listed, and a reference number an authorized watchmaker can confirm.
Why does the 37 mm figure matter?
Case size drives everything else in a dress watch: dial balance, lug curve, and how the watch sits under a cuff. Squeezing a manual-wind movement into a 37 mm shell forces a thicker case, and that extra height is visible from the side. Genuine small Portugieser watches stay thin because the automatic movement was designed around that case.
What are the risks of buying a counterfeit Portugieser?
Counterfeit watches carry no manufacturer warranty, cannot be serviced with genuine parts, and lose nearly all resale value. Importing them into the United States is illegal, and shipments are subject to seizure and destruction. A watchmaker can identify a replica in minutes, which makes the purchase a poor store of value before any legal exposure.
FAQ
Does IWC make a 37 mm Portugieser?
Yes, the Portugieser Automatic 37, but only with an automatic movement. There is no hand-wound 37 mm Portugieser in the current collection.
How much does a genuine Portugieser cost compared with a replica?
Genuine Portugieser models sell in the thousands of dollars, with the hand-wound 8 Days priced above the automatics. Replica pricing reflects counterfeit goods, not watchmaking value, and the money is unrecoverable.
Can a jeweler spot a fake Portugieser hand wound 37 immediately?
Usually yes. Case thickness, movement finishing, and dial printing are quick checks for anyone who handles IWC watches regularly.
