Short answer
A replica IW323704 is a counterfeit copy of an IWC Ingenieur Automatic. IWC does not make it, sell it, or service it. The number IW323704 is a real IWC reference. Copy sellers reuse that number to sound official.
What the reference is
IW323704 sits in the IWC Ingenieur line. Ingenieur watches of that era use an integrated case and bracelet, a soft-iron inner case for magnetic shielding, and a screw-down caseback. IWC publishes case material, case size, movement, and production years in its own records. Published case sizes for this reference differ between secondary sources. Check the IWC record and the caseback stamp before you treat any number as final.
How copies are built
Most copies of this reference come from a small group of workshops in Guangdong, China. A steel case is cut on CNC machines, then brushed and polished. Dials are stamped and printed. Bracelets use stamped or milled links. Movements fall into three groups: quartz, Asian automatic clones, and modified ETA or Sellita units. No counterfeit carries the IWC movement fitted to the genuine watch.
Flaws seen on fakes
- Date window position and date font. Genuine printing stays sharp at 10x magnification.
- Bracelet fit. Copies show gaps at the end links and a loose clasp.
- Caseback engraving depth. Laser etching looks shallow next to stamped numbers.
- Dial text. Letter spacing on the logo and the Automatic line drifts.
- Crown threads. Cheap crowns cross-thread and leak.
- Serial numbers that repeat across many units.
Price range
Counterfeit IW323704 listings run from about $60 to $700. Sellers label the top tier as Swiss made or 1:1. The parts are not Swiss. A Swiss movement claim cannot be checked without opening the case, and even then a clone is hard to separate from a genuine ETA.
Legal position in the United States
IWC is a registered trademark. Trafficking in counterfeit goods is a federal crime under 18 U.S.C. 2320. US Customs and Border Protection seizes counterfeit watches at ports of entry. A counterfeit carries no manufacturer warranty and cannot be serviced by IWC or an authorized service center. Resale adds civil and criminal exposure for the seller.
Checks if you handle one
- Record the caseback reference and serial.
- Ask IWC or an authorized dealer to confirm the serial against their records.
- Weigh the watch. A light bracelet points to a copy.
- Do not pressure test a watch with unknown seals.
Service and parts
IWC service covers parts, gaskets, and a warranty on the work. Counterfeit owners use independent shops. Those shops can clean and oil a common clone movement. They cannot source IWC hands, crowns, crystals, or bracelet links. When a copy part breaks, the watch often becomes unusable. No counterfeit matches a genuine IW323704.
