Short answer

IW93801 does not appear in IWC's published reference lists. The number shows up in marketplace listings and seller catalogs. It works as a listing ID for a replica watch sold in an IWC style. It is not a documented factory model number. Treat any spec sheet attached to the code as seller-supplied data.

How reference numbers work

Current IWC references use the letters IW plus six digits, for example IW371617. Older references use four digits, and the IW prefix was added later. A five-digit code such as 93801 matches neither pattern in the current catalog. That gap is the first sign the code came from a reseller, not from the brand.

What to confirm before paying

  1. Caseback photo. Compare the engraved number with the text in the listing. Mismatches are common.
  2. Movement model. Ask for the exact caliber name and photos of the movement. Blank answers mean the seller does not know.
  3. Case diameter and lug width in millimeters. Measure a watch you already own for comparison.
  4. Water resistance testing. Most replicas are assembled without pressure testing. A 100 m claim with no test record is a guess.
  5. Return terms in writing. Get the window length and who pays return shipping.

Crystal, case, and finish

Sellers list sapphire crystal on some units and mineral glass on others. Both scratch at different rates. Stainless steel cases are standard. Plated gold finishes wear through at the edges of lugs and the crown. Ask for close photos of those areas.

Legal status in the United States

Goods that carry a trademarked name or logo without authorization are illegal to import and sell in the US. 18 U.S.C. § 2320 covers trafficking in counterfeit goods. U.S. Customs and Border Protection inspects and seizes shipments at ports of entry. A buyer can lose the item and the money paid for it. Penalties fall on sellers and importers, not only on manufacturers.

Bottom line

IW93801 is a seller code. No public IWC record supports it. Request caseback and movement photos, confirm measurements, and read the return policy. Know the import risk before you order.
