Quick answer
A fake IW323716 is a replica built to look like the IWC Ingenieur Automatic reference IW323716. Replica makers match the case outline, the integrated bracelet, and the dial layout, but they seldom match the engraved reference and case number, the finishing hidden under the end links, the dial text weight, or the movement decoration. One confirmed mismatch is enough reason to walk away.
What you need
- A 10x jeweler loupe
- Clear photos of the case back, dial, and clasp
- Catalog images of the genuine IW323716 for side-by-side comparison
- A postal scale if you plan to weigh the watch
Step-by-step authentication
- Read the reference number on the case back and confirm it reads 323716, not a shortened or mistyped version.
- Locate the case number as a separate engraving and write it down for later verification.
- Check that the case number and the reference number are different numbers, since replicas often repeat them.
- Study both engravings with a loupe. Genuine engraving has sharp edges and even depth, while laser etching on a fake looks sandy and shallow.
- Inspect the dial text and confirm the lettering is crisp, aligned, and spaced in proportion to the marker ring.
- Look at the date window for a cleanly cut aperture with the disc centered behind it and the numerals level.
- Run a fingertip along the case flanks and the bracelet end links, since burrs or sharp lips point to a replica.
- Turn the bracelet screws. Real screws sit flush and rotate, while many fakes use pins with decorative screw heads.
- Weigh the watch on the bracelet and compare the figure against the published weight for a steel IW323716.
- Screw the crown in and out, noting any grit, wobble in the stem, or rough thread.
- Hold the watch to your ear and tilt it. A grinding or rattling rotor is common on counterfeit movements.
- Ask a watchmaker to open the case back and check for signed rotor engraving, correct jewel count, and finished bridges.
- Send the case number to an IWC service center and ask for written confirmation of the reference.
- Compare the asking price against current market prices for a genuine IW323716, since a figure far below market points to a fake.
Red flags that confirm a fake
- Reference number printed on a sticker or hang tag instead of engraved in the metal
- Dial text that touches the marker ring or sits off center
- A case number that matches the reference number
- Bracelet screws that do not turn or are molded into the link
- Papers with a printed reference that does not match the case back
- A case back with uneven polishing and a blurred logo stamp
If you already bought one
Stop wearing the watch and keep every message, photo, and payment record tied to the sale. Open a dispute with your payment provider and report the listing on the platform where you found it. A watchmaker can supply a written opinion that the case, reference, and movement do not match IW323716, which supports a chargeback. In the United States you can also report the seller to the Federal Trade Commission, and to U.S. Customs and Border Protection if the watch was shipped from abroad.
