Short answer
IWC Schaffhausen has no catalog model called a "100 anniversary" watch. The brand was founded in 1868. Its 150th year fell in 2018, and IWC marked it with the Portugieser Jubilee collection. A listing that sells a "fake IWC 100 anniversary copy" borrows an anniversary label that does not appear in IWC reference records. Treat the phrase as ad text, not as a model name.
What the anniversary references are
IWC anniversary pieces carry the year of the milestone on the case back, not a generic "100" badge. The 2018 Jubilee models used lacquered dials in blue or white with contrasting print, and case backs engraved for the 150th year. Reference numbers sit on the case back and on the warranty card. A seller who cannot state a reference number has no anniversary watch to show.
Why replica listings use "100 anniversary"
The phrase carries weight with buyers who do not know the IWC timeline. It suggests a limited run and a high original price. Listings pair it with stock photos of genuine watches. The photo and the shipped item are different objects in most cases.

Checks on the watch
- Case back: engraving on a genuine IWC stays sharp at 10x magnification. Engraving on a copy shows rounded edges and uneven depth.
- Dial print: "Probus Scafusia" and the brand name sit in a straight line. Copy dials show spacing drift between letters.
- Movement: an in-house caliber with a signed rotor. Copies use third-party movements, often with no marking under the rotor.
- Weight and finish: steel cases weigh more than plated brass. Plated edges show a copper tone at wear points.
- Sub-dial spacing: the running seconds and chronograph counters sit on the correct axis on genuine dials.
- Crown: signed, with crisp relief and a straight stem line.
Papers, boxes and serial numbers
Genuine IWC watches ship with a warranty card that carries the reference and serial. The serial repeats on the case back. Copies ship with printed cards that do not match. Ask for the serial and the reference, then compare both to the case back photo. A mismatch ends the deal.

US legal exposure
Counterfeit watches are illegal to import and to sell in the United States. Trafficking in counterfeit goods is a federal offense under 18 U.S.C. 2320. U.S. Customs and Border Protection seizes shipments that carry infringing marks. Buyers risk loss of payment and seizure of the item. Resale of a counterfeit watch carries the same exposure.
Practical path
If the goal is an anniversary IWC, buy from a dealer who lists the reference number, the serial, and dated photos of the watch in hand. If the goal is a low-cost look-alike, note that the "100 anniversary" wording describes nothing in the IWC catalog, and the item ships with no brand support.
