Short answer
A watch sold as a counterfeit Portofino ref IW938 is not a valid IWC reference. Genuine IWC reference numbers use the IW prefix followed by four digits, so “IW938” is incomplete. Treat any listing that uses that reference as a warning sign, not proof of authenticity. Verify the full caseback reference, serial, paperwork, and seller before you pay.

What the IW938 label tells you
IWC reference numbers normally appear on the caseback and paperwork. A truncated number such as IW938 often shows up in copied listings, recycled stock descriptions, or counterfeit product pages. Ask for a clear photo of the full caseback and compare the reference and model name with IWC’s official Portofino listings. Do not accept a screenshot, cropped image, or catalog photo as proof.
Verify the watch before payment
- Request a close, straight-on photo of the caseback with the full reference and serial visible.
- Compare the reference format and model details with the official IWC Portofino range.
- Ask for dated photos of the dial, crown, clasp, box, warranty card, and service papers.
- Check that the seller’s name, invoice, and payment account match the paperwork.
- Have a qualified watchmaker or authorized dealer inspect the watch before you send final payment.
Common red flags
- Reference “IW938” shown without the normal four-digit code.
- Price far below the market for a comparable Portofino.
- Stock photos, blurred caseback images, or refusal to show the serial.
- Pressure to pay by wire, gift card, or a private account.
- No return policy, no warranty terms, or paperwork that cannot be verified.
If you already paid
- Stop any further payments to the seller.
- Save the listing, messages, photos, receipt, and payment record.
- Send a written return and refund request through the platform.
- Open a dispute with the marketplace or your card issuer.
- Report the listing to the platform and to the relevant consumer or customs authority.
Why the reference check matters
Counterfeit watches can carry incorrect references, weak materials, and no manufacturer warranty or service support. In the US, importing counterfeit goods can lead to seizure and other legal exposure. If you want a Portofino, buy from an authorized dealer or a verified pre-owned seller with provenance. A low price does not offset the risk of a watch that cannot be serviced, insured, or resold.
