Quick answer
A fake IWC IW323724 usually fails on details that are hard to copy: caseback engraving, dial print, bezel action, crown feel, and movement finish. Confirm the reference and serial first, compare the watch with photos of the exact IW323724 variant, then have a watchmaker open the case. Boxes and papers are easy to fake and prove nothing on their own.
What the IW323724 is
The IW323724 is a reference in the IWC Aquatimer Automatic 2000 line. It is a stainless steel dive watch with a rotating bezel and an IWC automatic movement. The model has a specific case shape, dial layout, and engraving style. Counterfeit versions often copy the general look and miss the reference-level details.
Prerequisites
- Good light and a loupe
- Catalog photos of the IW323724
- A watchmaker who can open the case
- The seller's paperwork and service records
How to spot a fake IW323724
Confirm the reference and serial. Read the caseback engraving under magnification. The reference should read IW323724, and the serial should be crisp, evenly spaced, and consistent with IWC's format for that era. A shallow laser etch or a mismatched reference is a stop sign.
Compare case proportions. Measure the case and compare it with the catalog dimensions for the IW323724. Fakes often run thicker or have lugs with softer edges.
Inspect dial print and markers. Use a loupe on the logo, minute track, and date window. Genuine IWC print is sharp, and applied markers sit flat with clean edges.
Test bezel and crown. Turn the bezel through a full rotation and wind and set the crown. The bezel should index with firm clicks, and the crown should thread without grit.
Check the movement. Have a watchmaker remove the caseback. Look for IWC calibre markings, proper rotor engraving, and finishing that matches the reference. A generic movement with an IWC rotor is a fake.
Verify paperwork and seller. Match the warranty card, box, and service receipts to the serial. Ask an IWC authorized service center to confirm the serial if the seller allows it.
Red flags
- Reference number that does not match the dial or case style
- Bezel with weak clicks or back play
- Dial text that is thick, fuzzy, or off-center
- Caseback engraving that is shallow or uneven
- Movement that is not signed by IWC
- Seller who refuses an inspection
Bottom line
Buy the watch, not the story. A genuine IW323724 has crisp engraving, a precise bezel, a clean dial, and a correctly finished IWC movement. If any of those checks fail, walk away.
