A watch listed as "fake IW93835" or "IW93835 replica" is a counterfeit IWC Schaffhausen model sold under a reference number that does not match IWC's published numbering. Current IWC references carry an IW prefix and six digits, for example IW371617. Older models are cited with four-digit base numbers such as 3714. A five-digit form like 93835 sits outside both patterns. That does not prove the watch is fake by itself, but it does mean the number cannot be used as proof of anything. Check the watch and the seller's paperwork before money moves.

What the Number Tells You

Counterfeit sellers invent reference numbers, recycle numbers from unrelated brands, and copy numbers from real IWC models. A model page that shows "IW93835" next to photos of a Portugieser, a Pilot's Watch, or an Aquatimer is a sign that the listing was assembled from stock images. The reference should match the dial layout, case diameter, and movement IWC actually produced under that number.

Before You Check

  • Copy the full listing text, including the title and any spec table.
  • Save every photo at full resolution, especially the caseback and crown.
  • Write down the claimed case size, movement caliber, and production year.
  • Note the asking price and the seller's return policy.

How to Check a Watch Sold as IW93835

  1. Open IWC's official website and search the reference number in the model archive or contact form.
  2. Compare the digit count and prefix to IWC's current format of IW plus six digits.
  3. Ask the seller for a sharp photo of the caseback engraving, including the serial number.
  4. Read the engraved text. Genuine IWC engraving is crisp, evenly spaced, and cut into the metal. Shallow etch marks are a bad sign.
  5. Ask which caliber powers the watch and compare it with the caliber IWC lists for that family.
  6. Request the case diameter in millimeters and compare it with the official specification.
  7. Check the dial printing under magnification. Look at the "Schaffhausen" line, the index alignment at 12, and the date window edges.
  8. Inspect the crown and pushers. Genuine IWC crowns carry a polished logo and sit flush against the case.
  9. Weigh the watch if you can. Replica cases often run several grams off the specification.
  10. Take the watch to an authorized IWC service center or an independent watchmaker and ask for a movement and authenticity check.
  11. Walk away if the seller refuses an inspection, an escrow payment, or a written return window.

Red Flags in Listings

  • A reference number that returns no results on IWC's own site.
  • Photos reused from other sellers, catalogs, or auction archives.
  • A price far below the genuine market for the same model.
  • No serial number photo, or a blurred one.
  • "1:1," "mirror quality," or "super clone" in the description. These are replica trade terms, not IWC terms.
  • Payment by wire transfer, gift card, or crypto only.

Legal Note

Counterfeit watches infringe a trademark, and importing them into the United States can lead to seizure and destruction by U.S. Customs and Border Protection. A seller who ships a counterfeit item cannot offer a lawful warranty, service, or parts supply. If you already paid and the watch is fake, dispute the charge with your card issuer and report the seller to the platform and the relevant consumer authority.

Bottom Line

Treat "IW93835" as a marketing string until a real IWC reference matches it. Verify the number, the engraving, the caliber, and the dimensions, then have the watch inspected by a qualified watchmaker. If any of those checks fails, the listing is not worth the risk.
