Fake IW938982: the short answer
IW938982 does not match any reference in IWC's published catalog, and IWC stamps reference numbers in the IW plus six-digit format on the caseback and repeats them on the warranty card. A watch sold under that number is either listed with the wrong reference or it is a counterfeit. Work the checks in this order: reference and serial match, caseback engraving, dial print, movement, crown and pushers, then box and papers.
Fake IW938982 Comparison Chart
Step 1: Verify the reference and serial number
- Read the full reference off the caseback with a 10x loupe. Genuine engraving is crisp, sits in a clean recess, and shows no burrs or double-cut edges.
- Compare those digits with the number printed on the warranty card and the hang tag. All three must match character for character.
- Look up the number in IWC's own online catalog. If nothing returns, treat the watch as unverified and stop.
- Check the serial number as a separate field. It must differ from the reference and appear on both the caseback and the paperwork.
Step 2: Inspect the case and caseback
On a genuine IWC the brush direction on the lugs runs straight and the polished bevels are cut, not stamped. Counterfeit cases show soft edges, uneven brushing, and a caseback that sits proud of the midcase. The engraving depth is uniform on a real watch and shallow or rounded on a fake.
- Engraved text should be sharp at 10x, with even spacing between letters.
- Sapphire display backs have a flush fit and no glue line at the crystal edge.
- Caseback screws line up with the holes and sit flush on all six positions.
- Weight should feel dense for the case size, not hollow.
Step 3: Check the dial and hands
- Applied indices sit level with no gaps under the base.
- Lume fill is flat and even, with no overflow onto the frame.
- Dial print is raised and clean under magnification, not dot-matrix.
- Date and day wheels use the correct font and align square in the window.
- Hands have beveled edges that catch light in a straight line.
Step 4: Look at the movement
- Identify the calibre number on the rotor or bridge.
- Confirm that calibre matches the reference in IWC's catalog spec sheet.
- Inspect finishing: Geneva stripes should be straight and evenly spaced, perlage should overlap in a consistent pattern.
- Check rotor engraving depth. Fakes use light laser etching that fades at an angle.
Step 5: Check crown, pushers, and winding
- Unscrew the crown and count the threads. A genuine screw-down crown engages in about two and a half turns with no grit.
- Press each chronograph pusher. The start, stop, and reset should click with a distinct break, not a mushy travel.
- Wind the watch by hand and listen. A clean ratchet runs smooth with no scrape.
Step 6: Match box, papers, and price
- Card, booklet, and hang tag must carry the same reference and serial.
- Price well under the market for that model is the strongest single signal.
- Ask for the original purchase date and dealer name, then verify the dealer exists.
Why replica listings use numbers like IW938982
Invented or transposed reference numbers appear often on replica listings. A number that does not exist in the catalog cannot be compared side by side with a real watch, so the buyer has no baseline. Treat any unfamiliar IW number as a prompt to check the manufacturer's own list before you send money.
