Short answer
A "fake IW9380001" is a replica of an IWC watch, not a watch built by IWC Schaffhausen. IW is the IWC reference prefix, and numbers in this format appear on the caseback of modern IWC models. I could not confirm which model carries the exact number IW9380001 from the digits alone. Ask the seller for a macro photo of the caseback and the warranty card before you pay. A genuine IWC in steel starts near $5,000 new. A replica runs $150 to $900.

What the reference number shows
IWC stamps two sets of digits on a watch: a case number and a serial number. Both sit on the caseback. On a replica the two numbers often repeat across a batch, so a second watch from the same seller shows the same digits. Compare photos from two buyers. Matching serials mean a copy.
Price test
If a watch sold as a genuine IWC lists under $1,000, it is a replica. No exception exists for steel three-handers, box and papers, or "estate finds." Sellers use these words to explain a low price. The price is the tell.
What to check on the watch
- Movement: IWC uses in-house calibers. Replicas use Asian movements, a 7750 base for chronographs and a clone automatic for three-handers. Ask for a photo of the movement with the caseback off.
- Caseback engraving: depth and font. Laser etching looks shallow under a loupe. Genuine engraving cuts into the metal.
- Weight: a steel case weighs more than plated brass. A 40 mm steel case lands near 70 to 90 g without the strap.
- Crystal: sapphire with anti-reflective coating. Many IWC models coat both faces. Replicas coat one side.
- Crown: thread feel and gasket. A gritty crown points to a copy.
Risks
- No warranty. IWC service centers reject counterfeit watches and return them unrepaired.
- Water resistance is a claim, not a rating. Few replicas pass a pressure test.
- US Customs can seize counterfeit imports. Seized goods are destroyed and the buyer has no refund route.
- Resale value is close to zero. Replica forums set the used price at half the new replica price.
Steps before you pay
- Request macro photos of the dial, caseback, crown, and movement.
- Request a photo of the watch next to today's date on a card.
- Confirm the reference with IWC or an authorized dealer.
- Pay with a method that allows a chargeback. Bank transfer gives you no recourse.
Buyers who want the look of an IWC at replica prices should price the watch as a replica and skip any seller who calls it genuine.
