A fake IW371655 is a replica of the IWC Portugieser Chronograph reference, and the fastest way to judge one is to compare case proportions, dial printing, subdial spacing, and movement finish against clear photos of the genuine reference. The reference number matters because replicas often mix details from several Portugieser generations.
What the IW371655 reference represents
The IW371655 belongs to the Portugieser Chronograph line, a family known for a round case, a thin bezel, applied numerals, and two subdials stacked at 12 and 6 o'clock. Buyers searching for a fake iw371655 usually want the look of that clean, symmetric dial without paying genuine IWC pricing. That makes the dial the first place to check, since the case and movement are harder to inspect in a photo.
Dial and case checks for a fake IW371655
- Dial printing: genuine Portugieser text is crisp, evenly spaced, and aligned with the subdial centers. Fuzzy edges, uneven weight, or text that drifts off-center are common replica faults.
- Subdial spacing: the two subdials should sit on a clean vertical axis. A fake IW371655 may show one subdial slightly high, low, or off-center.
- Applied numerals: look for sharp edges, consistent polishing, and correct height. Flat or overly thick numerals are a warning sign.
- Case finish: check the brushed and polished transitions on the lugs. A replica often has soft edges or a wide gap where the case meets the bezel.
- Crystal and dial color: reflections should be controlled, and the dial color should stay consistent across the surface. A washed-out or overly glossy dial is a clue.
Movement and caseback clues
Ask for a clear photo of the caseback and, if possible, the movement. Genuine IWC finishing is clean and consistent, with proper engraving depth and sharp lettering. A fake IW371655 often uses a generic chronograph movement with rough rotor finishing, shallow engraving, or incorrect bridge shapes. For closed casebacks, focus on the engraving quality, the reference number format, and the fit of the caseback to the case.
What first-copy quality means
The term first copy is used in the replica market to describe a higher-grade replica, but it is not a standardized grade. Sellers use it loosely. In practice, a first-copy IWC Portugieser should have better dial printing, closer subdial placement, and a more accurate case profile than a budget replica. It still is not a genuine watch, and the gap shows up in movement finishing, long-term reliability, and service support.
Buying checklist before you pay
- Compare the listing photos with known reference photos of the IW371655, not with other replicas.
- Ask for close-ups of the dial text, subdials, lugs, caseback, and clasp.
- Confirm the movement type and whether the chronograph functions reset to zero as it should.
- Check the return policy and whether the seller accepts inspection on arrival.
- Treat a price that is far below the market for a genuine Portugieser as a warning, not a bargain.
Legal and ownership notes
Counterfeit watches sold as genuine are illegal in many markets, and the FTC treats such sales as deceptive. A replica sold openly as a replica is a different category, but it still carries risk: no brand warranty, limited service options, and weak resale value. If you want the IW371655 look, buy from a seller who describes the item as a replica and gives you clear photos before purchase.
