A fake IW371489 is any watch presented as IWC's Portugieser Chronograph reference IW371489 that did not come out of IWC's factory in Schaffhausen. The real watch is a 41 mm stainless steel chronograph with an IWC chronograph calibre, a signed dial, and an engraved case back. Copies match the outline at arm's length and fall apart under a loupe, a scale, or an opened case back.
What Is the IW371489?
IW371489 belongs to the IW3714 generation of the IWC Portugieser Chronograph, a line that entered the catalog in the late 1990s and stayed for more than two decades. These watches share a 41 mm case, two subdials, applied numerals, and a date aperture. Depending on the year of production, the movement is either the Valjoux 7750 based calibre 79350 or IWC's later calibre 69355 with a column wheel.
How Can You Tell a Fake IW371489 From a Genuine One?
Four checks catch most copies: the case back engraving, the dial printing, the movement finish, and the feel of the pushers.
Does the Case Back Engraving Look Right?
Genuine IWC engraving is cut deep and even, with the reference number, serial number, and the Probus Scafusia motto in the correct typeface. Copies often show shallow etching, uneven letter spacing, or a serial that does not match the paperwork. A reference and serial that belong to different production years is a warning sign.
Is the Dial Printing Sharp?
Under 10x magnification, genuine dial text has clean edges and consistent thickness. Replica dials show ink bleed, uneven lume plots, and subdial rings that sit off center from the hand pivots. Applied numeral thickness and the finish of the hands are also frequent tells.
What Movement Sits Inside?
A genuine Portugieser Chronograph runs an IWC calibre with a decorated rotor, signed bridges, and a crisp chronograph reset. Many fakes hide an undecorated Asian chronograph movement behind a printed rotor plate. A watchmaker can confirm the calibre in minutes once the case back is off.
How Do the Crown, Crystal, and Pushers Feel?
Genuine pushers have a short, firm travel and the reset snaps back to zero in one motion. Replicas often feel spongy or grind on start. Crystal clarity and anti reflective coating quality separate a mid-tier copy from a cheap one, and the crown engraving on a fake is usually shallow.
Is a "Fake" the Same as a Replica?
A fake is sold as the genuine article, usually with forged boxes and papers, and that sale is fraud. A replica is openly sold as a copy at a fraction of the price of the real watch, and the buyer knows exactly what they are getting. The two can look identical in photos; what separates them is what the seller claims.
In the United States, US Customs and Border Protection can seize counterfeit goods at import, and selling a copy as genuine exposes the seller to trademark claims.
What Should You Check Before Buying a Replica IW371489?
- Confirm the listing says replica, not genuine.
- Ask for photos of the actual unit, including the case back and crown.
- Ask which movement the watch uses and whether it is a 7750 based chronograph.
- Check the case size, lug width, and crystal material against IWC specs.
- Read the return policy before you pay.
FAQ
How much does a genuine IW371489 cost?
Pre owned examples trade for several thousand dollars depending on condition, box, and papers. A price far below that range for a watch described as genuine is the clearest sign of a counterfeit.
Can a jeweler spot a fake IW371489 from a photo?
Photos can raise suspicion but rarely settle the question. Opening the case back and checking the movement, engraving, and serial is the reliable path.
Do replica IW371489 watches use sapphire crystal?
Better replicas often use sapphire, though the anti reflective coating is usually thinner than IWC's. Entry level copies fall back to mineral glass, which scratches and reflects more light.
