What IW545167 means
IW545167 is an IWC reference number. It sits in the Portuguese Hand-Wound family, a line of manual-wind watches listed at 44 mm with small seconds at 6 o'clock. Reference suffixes track case metal and dial color. IWC publishes a full spec sheet for its own references. Replica sellers do not. Treat the number as a search tag, not a spec list.
How sellers label the reference
Listings use "IW545167," "545167," or "IW5451" in the title. The same tag shows up on pages with different case sizes, movements, and strap materials. A tag match proves nothing. Ask for measurements in millimeters: diameter, thickness, and lug width. Ask for the movement type: hand-wound, automatic, or quartz. Quartz copies of this reference exist and sit at the bottom of the price range.
Details that separate one copy from another
- Case diameter in millimeters, measured with calipers.
- Dial layout: small seconds subdial position and the printed track.
- Hand shape and finish. Blued steel versus painted.
- Caseback engraving depth and font.
- Strap material and buckle type.
- Movement finish, if the caseback is a display back.
Price bands
Ask prices run from about $70 to $600. Quartz versions cluster under $120. Automatic and hand-wound versions with decorated movements sit above $200. Seller photos repeat across price tiers. Ask for a timestamped photo of the actual piece.
Legal status in the United States
Importing a watch that carries a counterfeit trademark is illegal in the US. Customs and Border Protection can seize the shipment. 19 U.S.C. § 1526 covers the import ban. The Lanham Act covers civil claims. Penalties can reach the buyer as the importer of record. No seller promise changes that.
Checklist before you pay
- Confirm case diameter and lug width in writing.
- Confirm movement type and power reserve claim.
- Ask for photos of the actual watch, not stock images.
- Ask about the return address and shipping method.
- Assume the order may be seized. Decide if the loss is acceptable.
What the number does not tell you
Two listings with the same reference can ship different watches. Some sellers attach IWC references to generic 42 mm or 45 mm cases. The number also says nothing about water resistance, crystal material, or warranty. Any claim about those items needs a separate answer from the seller. That answer may still be wrong.
