Short answer
IW93820 does not appear in IWC Schaffhausen's public catalog, and it does not fit the number blocks IWC uses on watch cases. IWC prints references as IW plus digits. Known families sit in groups such as 32xx, 37xx, 38xx, 43xx, 50xx, and 51xx. A base number of 9382 has no entry in those groups. A search for "fake IW93820" points to a seller code, a typo, or an invented number, not to a real watch model.
How IWC reference numbers work
IWC writes a reference as IW plus a base number plus a variant. The Portugieser Chronograph carries references such as IW371617. The Pilot's Watch Chronograph 41 carries references such as IW388103. The digits after IW group by collection and case, not by production year. IWC also uses four and five digit caliber numbers, for example the 82000 and 98000 families. Buyers mix caliber numbers with case references. That mix is one source of odd codes in listings.
Where the number may come from
- A typo for a real reference such as IW371617 or IW388103.
- A caliber number printed on a movement, not a case reference.
- A wholesaler catalog code that sellers copy into product pages.
- An invented number used to avoid brand takedown requests.
Checks that settle the question
- Search iwc.com for the number. Current models appear by collection with full references.
- Compare the case back engraving with the number on the card or papers.
- Identify the movement. Replica sellers use one movement across many listings.
- Ask for a clear photo of the case back and the movement under light.
- Ask for the serial number and check it against service records.
What replica listings in this code range contain
Wholesale listings that use codes like IW93820 sell on tier. Low tiers use quartz. Middle tiers use 21-jewel automatics from Miyota or Seagull. Top tiers use a clone automatic built to look like an IWC caliber. Case metal claims run from 316L stainless to "904L" steel. Gold color comes from plating, PVD, or gold fill, not solid gold. Water resistance claims go untested on most units. Weight sits below the genuine piece because the movement and case differ.
Legal facts on imports
In the United States, 19 U.S.C. 1526 lets U.S. Customs and Border Protection seize imported goods that carry a counterfeit mark. 18 U.S.C. 2320 covers trafficking in counterfeit goods and carries criminal penalties. A personal-use purchase does not create an exemption for import. Trademark holders can bring civil suits against sellers and distributors. Customs destroys most seized watches.
Bottom line
No documented IWC watch carries reference IW93820. Treat any listing with that code as a seller label. Ask for the real reference, the caliber, and a case back photo. If the seller cannot name a reference that appears on iwc.com, the code is not a model number.
