The replica IW371652 is a counterfeit version of the IWC Portugieser Chronograph, a 41 mm stainless steel bicompax chronograph powered by the in-house calibre 69355. The genuine watch puts two subdials in a vertical stack at 12 and 6, and that layout is the single hardest thing for a copy to get right. Top factory replicas use a custom automatic chronograph movement and a case built to original thickness, while cheap copies hide a quartz or mismatched movement behind a dial with the wrong subdial spacing.

What specs does a replica IW371652 have to match?

Every credible copy is judged against the same short list of genuine specifications. If two or three of these are off, the watch fails on the wrist.

  • Case: 41 mm stainless steel, about 13 mm thick, thin bezel, long curved lugs.
  • Dial: two subdials at 12 and 6, printed Arabic numerals, feuille hands, date aperture at 3.
  • Movement: IWC calibre 69355, automatic, 28,800 vph, roughly 46 hours of power reserve.
  • Crystal: domed sapphire with anti-reflective coating on both faces.
  • Water resistance: factory rated to 3 bar, which means splash resistance only.

What are the replica quality tiers for the IW371652?

  1. Entry tier: quartz or basic automatic, mineral glass, flat dial print, subdials sitting too close to the center.
  2. Mid tier: Asian 7750-based chronograph, sapphire crystal, acceptable case finishing, slightly thick date font.
  3. Top factory tier: custom clone movement with correct subdial positions, correct hand stack, gen-spec case thickness and crisp dial text.

Most buyers who care about the dial eventually move from mid tier to the top tier, because the vertical subdial layout exposes every shortcut.

How do you spot a low-quality IW371652 replica?

  • Subdials sit too low or too close together, which throws off the whole face.
  • Date window edges look rough and the font is too bold compared with the genuine aperture.
  • Case thickness runs past 14 mm, so the lugs float above the wrist.
  • Caseback engraving is shallow, uneven, or the reference number is misspelled.
  • The chronograph seconds hand stutters or resets off the 12 marker.

What should a replica IW371652 cost?

Top-tier examples usually run $350 to $600 depending on movement and bracelet choice. Mid-tier versions land between $150 and $300, and entry-level quartz copies sell under $100. A price far below those bands almost always means a stock photo and a quartz movement that arrives looking nothing like the listing.

What is on the pre-purchase checklist?

  1. Ask for timestamped photos of the actual watch, not catalog renders.
  2. Confirm the movement name and beat rate in writing.
  3. Request a close-up of the caseback and the dial printing.
  4. Check whether the seller offers any return window.

Is a replica IW371652 legal to buy?

No. A fake watch infringes IWC's trademarks, and counterfeits can be seized by customs on import. Replicas also carry no warranty, no service support, and no resale value. Treat the purchase as a novelty buy with real legal and financial risk attached.
