IW93870 is not a reference in IWC Schaffhausen's public catalog. IWC reference numbers use the prefix IW plus five digits. Published examples include IW3716 (Portugieser Chronograph), IW3777 (Pilot's Watch Chronograph) and IW5007 (Portugieser Automatic). No model numbered 93870 appears in that list. Listings that use "IW93870" sell replica watches. Sellers in this market also use the terms first copy, mirror copy and AAA copy.
Why the Number Shows Up in Listings
Replica sellers shift or invent reference numbers. A number close to a real IWC reference looks plausible to a buyer and does not match a trademark record that a marketplace takedown system can flag. This explains gaps in sequence and numbers with no catalog entry.
Some sellers assign one number to several case sizes and dial colors. The same "IW93870" listing can ship a 40 mm case in one order and a 42 mm case in the next. No published specification sheet exists for the number, so measurements come from the seller.
Checks on a First Copy Watch
Ask the seller for these measurements and compare them to the real model the watch copies:
- Case diameter in mm and lug-to-lug length.
- Movement type: quartz, automatic with a Miyota or Seiko base, or a clone of an ETA or Sellita caliber.
- Caseback engraving: font, depth, spelling of "Schaffhausen".
- Dial printing: index alignment at 12, date window position.
- Weight in grams. Steel replicas run 20 to 40 grams lighter than the genuine watch in most cases.
- Strap or bracelet material and clasp markings.
Price Range
First copy and mirror copy IWC-style watches sell between $150 and $600. Genuine IWC Pilot's and Portugieser chronographs carry retail prices from about $6,000 to $12,000. A listing below $80 points to a quartz movement and a plated case. Plating wears through in months.
Legal Position in the United States
Counterfeit watches infringe registered trademarks. U.S. Customs and Border Protection can seize shipments at entry and destroy them. Sellers and importers face civil damages and criminal penalties under 18 U.S.C. 2320. A single watch bought for personal use carries lower risk than a bulk import, but the item can still be seized.
What Is Not Known
No factory specification sheet exists for IW93870. Case size, movement and materials vary by seller and by batch. Treat any stated spec as seller-supplied.
