What "fake IW323745" means
A fake IW323745 is a counterfeit watch sold as an IWC Ingenieur Automatic with reference number IW323745. The reference is the model code IWC stamps into the caseback, and it is one of the details copy makers get wrong most often. Authentication is a comparison task: you match the watch in your hand against IWC's published data and against the physical features that cost real money to reproduce.
Prerequisites
- A 10x jeweler's loupe
- Digital calipers
- Bright, diffused light and a plain white surface
- Reference photos of a confirmed genuine IW323745, from an IWC boutique or an authorized dealer
How to check an IW323745
- Read the caseback engraving. IWC reference numbers use the format IW plus six digits, so IW323745 should appear exactly that way, with the serial number separate and close by.
- Examine the engraving under the loupe. Genuine IWC caseback text is cut into the metal with crisp, sharp walls. Laser-etched or stamped copies look shallow, rounded, or fuzzy at the edges.
- Measure the case with calipers. Compare the diameter, thickness, and lug width to the figures IWC lists for the reference. Copies usually run 0.3 mm to 1 mm off in at least one dimension.
- Study the dial printing. Check the brand name, the "Automatic" line, and the minute track for even letter spacing and clean serif shapes. Look for ink that sits flat instead of raised.
- Inspect the hands and markers. Genuine hands are polished on the bevels and matte on the flats. Fakes show tool marks, uneven lume fill, or markers that do not line up with the printed track.
- Check the crown and case flanks. The crown should seat flush, turn with light resistance, and show sharp knurling. Smooth or oversized crowns point to a copy case.
- View the movement through the display back. Confirm the caliber number engraved on the movement matches the reference, then inspect rotor engraving, perlage, and Geneva stripes. Fake finishing is coarse and uniform.
- Verify the serial and reference together. Contact an IWC authorized dealer or service center and ask them to confirm that the reference and serial belong to the same production run.
- Examine the box, warranty card, and booklet. Genuine cards carry printed reference and serial data that match the watch, with consistent fonts and no spelling errors.
Red flags that end the discussion
- Reference and serial numbers that do not match the paperwork
- Caseback text in the wrong font, weight, or order
- Case dimensions outside IWC's published spec by more than 0.2 mm
- Movement finishing that looks painted rather than cut
- A seller who refuses an in-person inspection or a service center check
Verification you should not skip
Any single check can be passed by a good copy. The reference engraving, the case measurements, the dial print, and the movement finish have to agree with each other and with IWC's records. If a seller blocks the service center check, treat the watch as counterfeit and walk away.
