A fake IW371625 is a counterfeit copy of the IWC Portugieser Chronograph Classic, a 42 mm stainless steel chronograph built around an in-house 89361 calibre. Genuine examples carry a matching reference number, case serial, and movement finishing that replica makers almost never reproduce. The three fastest checks are the movement visible through the display back, the dial printing under a loupe, and the engraving on the caseback.
What is the IWC IW371625?
The IW371625 sits in the Portugieser Chronograph Classic family, which pairs a clean two-register layout with IWC's own automatic chronograph movement. Typical traits include a 42 mm case, a domed sapphire crystal with anti-reflective coating on both faces, applied numerals, and a railroad minute track. Water resistance is modest, so the watch is built for daily wear rather than swimming.
A genuine example sells for several thousand US dollars on the secondary market. A counterfeit usually costs a small fraction of that, which is the first signal that something is wrong.
How do you spot a fake IW371625?
Work through these checks in order, ideally with good light, a loupe, and a photo of the genuine reference beside you.
- Movement. The genuine 89361 shows Geneva stripes, blued screws, and crisp engraving of the IWC name and calibre number. Most fakes hide a generic chronograph movement with a different subdial layout or a decorative plate.
- Subdial positions. Genuine registers sit at 12 and 6 o'clock. Any factory-made copy built on a standard 7750 base shifts or resizes those counters.
- Dial printing. Real text is thin, sharp, and evenly spaced. Fake dials show fuzzy edges, thick strokes, and lettering that sits slightly off the applied markers.
- Caseback engraving. Reference and serial numbers on a genuine watch are lasered with fine, consistent depth. Counterfeits are shallow, uneven, or stamped, and often repeat a common serial across many units.
- Crystal coating. Double-sided anti-reflective coating gives a faint blue tint in angled light. Replicas usually have no coating or only one side, so the dial looks flat and reflective.
- Case finishing. Look at the transition between brushed and polished surfaces. Genuine edges are crisp and straight, while fakes show rounded edges, uneven brushing, or polishing compound left in the lugs.
- Crown, pushers, and strap. Pushers should start and stop the chronograph with a firm, short click. The pin buckle or deployant is signed, and the alligator strap has a regular square scale pattern.
- Papers and box. The warranty card must match the caseback serial and reference exactly, and the booklet print quality should be sharp.
Why are "super clone" IW371625 watches still detectable?
The in-house chronograph movement is the hard part. Copy makers can shape a case and print a dial, but the decorated 89361 with its column-wheel feel and long power reserve is expensive to fake well. Even the best replicas fail on movement architecture, engraving depth, and dial text once magnified.
Is buying a fake IW371625 legal?
In the United States, trafficking in counterfeit goods is illegal, and counterfeit shipments can be seized and destroyed by customs. Personal possession is a gray area, but reselling a fake watch is clearly unlawful and can carry civil and criminal penalties. Buyers also lose any recourse if the watch fails, because counterfeit goods carry no warranty and no service support from IWC.
What should you do if you bought a fake IW371625?
Stop wearing it and gather your evidence: listing photos, messages, payment records, and clear pictures of the caseback and movement. Open a dispute with your payment provider or credit card issuer promptly, since deadlines are short. Report the seller to the platform and, for imported goods, to the customs authority in your country.
How much does a genuine IW371625 cost?
Pre-owned genuine examples generally trade in the mid four figures to low five figures in US dollars, depending on condition, box and papers, and service history. Anything priced far below that range, especially from a private seller with stock photos, should be treated as counterfeit until proven otherwise.
