Short answer
IW544824 does not appear as a named model in IWC's public catalogs. IWC reference numbers use IW plus six digits. Replica sites use strings like this one as search labels, and two listings under the same label can show different watches. Ask the seller for the base six-digit reference, the case diameter, and the movement name before you compare anything.
How IWC reference numbers work
- An IWC reference starts with IW and carries six digits.
- The leading digits group the watch by family and caliber series. The Portugieser Chronograph family sits at IW3714. The Portugieser Automatic sits at IW5007.
- Trailing digits change with case metal, dial color, and strap.
That structure explains the mixed results behind a search for IW544824. Sellers reuse a partial number and vary the last digits. One digit can point to a different case metal or a different model line.
What buyers check on a replica listing
- Case diameter and lug width. A 44 mm case and a 40 mm case take different straps and wear differently.
- Dial layout. Subdial count and position change the replica's cost.
- Movement name, jewel count, and power reserve.
- Caseback text. Compare the font, spacing, and engraving depth against an authentic photo of the same base reference.
Price bands
Price tracks the movement, not the reference number. Quartz copies sit at the bottom. Automatic copies with a Chinese clone of an ETA 2824 or a Valjoux 7750 sit in the middle. Copies with a decorated movement and a Swiss-signed rotor sit at the top. Asking prices on replica sites run from about $80 to $500. The number printed on the dial does not change that range much.
US law and customs
Counterfeit watches are illegal to import into the United States. U.S. Customs and Border Protection can seize and destroy counterfeit merchandise, and it does so on single-parcel shipments. 18 U.S.C. § 2320 makes trafficking in counterfeit goods a federal crime, with penalties that rise for repeat offenses. A narrow rule lets a traveler carry one counterfeit article of each type in personal baggage when the value is $250 or less. That rule does not cover mail or courier parcels. A seized parcel is not refunded by the seller in most cases.
Steps to verify a listing
- Search IWC's site and auction archives for the six-digit base number, without the trailing variant digits.
- Ask for a caseback photo and compare the engraving against an authentic example.
- Ask for the movement name, the jewel count, and a photo of the rotor.
- Compare the price to the movement. A decorated automatic does not sell at a quartz price.
- Get the return terms and the payment method in writing. Offshore shippers often refuse returns.
Limits of this guide
IWC does not list IW544824 as a named model in the catalogs I can reach. If a seller claims a model name for this number, ask for that name in writing with a photo of the papers. If the name and the photo do not match a published IWC model, the number is a keyword and nothing more.
