A fake IW371459 is a replica of the IWC Portugieser Chronograph reference IW371459, a 41 mm stainless steel chronograph with two recessed totalizers at 12 and 6 o'clock, leaf-shaped hands, and a sapphire display back. Genuine examples carry an IWC chronograph calibre and sell new for roughly $7,000 to $9,000, so replicas trade between $150 and $900 and give themselves away through case thickness, dial printing, subdial reset behavior, and caseback engraving quality.
What does the reference IW371459 actually identify?
IW371459 belongs to the Portugieser Chronograph family, IWC's cleanest two-register chronograph design. The case measures about 40.9 mm to 41 mm across, sits roughly 12.3 mm thick, and is rated to 3 bar. Earlier production runs use the Calibre 79350, a heavily reworked Valjoux 7750, while later examples use the in-house Calibre 69355.
Every genuine example has a sapphire crystal front and back, an alligator strap with a signed pin buckle, and a rotor engraved with the Probus Scafusia seal. Those four details are the fastest place to start any authenticity check.
How do you tell a fake IW371459 from a genuine one?
Start with the case profile, then work inward to the dial and movement. Replica makers copy the silhouette well and the details poorly.
- Thickness: Genuine cases sit near 12.3 mm. Most fakes exceed 13.5 mm because a clone movement needs more room.
- Numerals: The applied Arabic 12 and 6 are solid metal with crisp edges. Fakes use plated or glued markers that look slightly flat under a loupe.
- Printing: The minute track and the IWC signature are razor sharp. On replicas the text often looks faint or slightly bold.
- Hands: Genuine feuille hands taper to a fine symmetrical point. Counterfeit hands are often thicker at the tip and unevenly polished.
- Crystal: Genuine sapphire has double anti-reflective coating and almost disappears. Mineral glass on cheap fakes shows a blue or green tint at an angle.
- Pushers: Genuine chronograph pushers feel firm and short-throw. Replica pushers feel mushy or travel too far.
Which movement details expose a replica?
Reset the chronograph and watch the two subdial hands snap back. Genuine calibres return to zero instantly and identically every time, while clone movements drift or land a fraction off center.
Look through the caseback for finishing. Real IWC movements show circular graining, blued screws, and a deep engraved rotor, while replicas use stamped plates with shallow etching and no anglage. Winding feel also tells: a genuine crown is smooth with light resistance, and a fake often feels gritty.
What should a fake IW371459 cost?
Entry replicas with quartz or basic automatic movements run $150 to $300. Mid tier versions with a clone 7750 sit near $350 to $550, and the best finished copies reach $700 to $900. Anything advertised as a genuine watch at a low four figure price is a counterfeit with forged paperwork.
Is buying a counterfeit watch legal in the United States?
No. Importing goods that carry a counterfeit trademark is prohibited, and shipments are subject to seizure and destruction by U.S. Customs and Border Protection. Selling a replica while presenting it as genuine also exposes the seller to trademark and fraud claims.
How do you verify a genuine reference before paying?
Ask for the caseback reference and serial, then confirm both against an IWC service record. Request close-up photos of the movement, the buckle, and the engraving between the lugs. A seller who will not provide these images is not selling a genuine watch.
