Short answer
IW328087 is an IWC reference number. IWC writes references as "IW" plus six digits. The number maps to one case, dial, and movement combination. Sellers of replica watches put the number in listing titles to signal which watch their product copies. IWC's own catalog is the source that confirms the mapping. No replica, at any price, comes from IWC.
What the digits point to
Listings that carry IW328087 describe a 40 mm watch with an integrated bracelet. That description should be checked against iwc.com before any comparison, because IWC reuses digit blocks across families and years. Two listings can carry the same number and describe different watches.
Checks to run on any listing
- Case diameter and thickness, in millimeters, measured with calipers.
- Case material. Steel and titanium are not interchangeable in a description.
- Dial printing: font weight, index alignment, date window position.
- Movement photos, including rotor engraving and caliber marks.
- Reference and serial engraving on the caseback.
- Total weight in grams. A hollow case reads low.
Movements in this price band
Sellers label movements as "super clone", "1:1", "AAA", or "Swiss ETA". These are marketing terms. No standards body defines them and no test separates one from another. What ships in most replicas of this reference is a Chinese automatic, often a copy of an ETA 2824 or a Miyota design. Beat rate, power reserve, and spare parts differ from the original caliber. Ask for a movement photo and a stated beat rate. A seller who cannot supply both has no support for the claim.
Material and weight
Titanium density is about 4.5 g/cm3. Steel density is about 7.9 g/cm3. A titanium case of the same volume weighs roughly 57 percent of a steel case. A listing that names titanium and quotes a steel-case weight describes one watch, not two.
Legal status in the United States
Counterfeit watches are illegal to import into the United States. US Customs and Border Protection can seize a shipment at the port, and the buyer has no refund route through the seller. Trafficking in counterfeit goods carries criminal penalties under 18 U.S.C. 2320. The first-sale doctrine does not cover counterfeit items, so a personal-use purchase does not create a legal exemption. A domestic seller of counterfeit goods can face the same exposure as an importer.
Price bands
Listings for IW328087 replicas appear from about $80 to about $700. Price does not prove quality. The same factory batch resurfaces under different seller names at different prices. Compare photos of the caseback and movement, not prices.
What is not known
IWC does not publish production totals per reference. Replica sellers do not publish factory names or batch numbers. Nobody outside the supply chain can confirm how many units of a given replica exist or when a batch changed. Claims about "version 3" or "best batch" are unverified by default.
