Short answer
In practice, "fake IW329062" gets used for two different things. One is a counterfeit: a watch engraved with an IWC reference number and sold as the real thing. The other is a replica, built to look like that reference and sold openly as a replica. They are not the same problem and the checks are not the same either. If you are buying used and the price sits far under market, assume counterfeit until the watch passes a hands-on inspection. If you are buying a replica, the question is build quality, not authenticity.
Start with the reference itself
I always pull the official spec first. IWC publishes case diameter, thickness, dial layout, strap options, and the movement for each reference on its own site. Write those numbers down before you look at a single photo. A large share of bad IW329062 listings fall apart right there, because the crown position, date window, or case thickness does not match the catalog. Counterfeiters copy photos, not calibers, so specs are the cheapest filter you have.
How to tell a counterfeit IW329062 from a genuine one
Case and finishing
Run a fingernail along the case flanks and lug edges. A genuine IWC is crisp and even. A counterfeit usually has soft, rounded transitions from over-polishing or a cheap stamp. Weight matters too. Hold the watch in your palm. A steel case of that size should feel dense and slightly cold. Check the crown: it should thread smoothly, sit flush, and line up with the case. Wobbly crowns and gritty threads show up on fakes all the time.
Dial and hands
Look at the printing under a loupe or a phone macro shot. Genuine dial text sits sharp and level, with no ink bleed between letters. The hands should be flat, polished on the top surface, and free of tool marks. Lume application should be even and stay inside the markers. On a fake you often see crooked applied markers, a date wheel with the wrong font, and lume that spills over the edge.
Movement and winding
Ask for a photo of the movement through the caseback, or a short video of the running seconds. A genuine IWC automatic winds with almost no rotor noise and holds a steady rate. A cheap counterfeit uses a rough clone movement that rattles, runs fast, or stops when you tilt it. If a seller refuses a movement photo on a watch at this price, walk away.
Caseback, engraving, and papers
Reference numbers, serials, and caseback text should be laser-crisp and consistent in depth. Fakes often show shallow, uneven engraving and misspellings in the model name. Boxes and papers are easy to fake, so treat them as decoration, not proof. Serials should match between the caseback and any card, and an authorized service center can confirm a genuine watch.
Red flags in listings
- Price well below the going rate for the reference, paired with "no time wasters" pressure language.
- Photos that go blurry exactly where the dial text or caseback would be.
- Stock images instead of photos of the actual watch.
- A seller who will not do a video call or meet at a watchmaker.
- Pressure to pay by wire or crypto with no escrow and no return window.
What a good replica does differently
A quality replica does not pretend to be genuine. It is sold as what it is, priced at replica level, and judged on its own terms: case shape, dial print, bracelet feel, and how the movement runs day to day. The tells are the same ones I listed above, but the bar is different. I care about whether the proportions look right on the wrist, whether the lume glows evenly, and whether it keeps time without fuss. Nobody is opening a caseback at a dinner table. Fit and finish, though, are visible from across the room.
Quick checklist before you buy
- Write down the official specs for IW329062 from the manufacturer's site.
- Compare case size, thickness, dial layout, and date position against the photos.
- Ask for a movement photo and a running video with the crown pulled and pushed.
- Check weight in hand and crown threading if you can meet in person.
- Meet at a watchmaker for a paid inspection on anything priced like a genuine.
- Use escrow or a payment method with buyer protection. No exceptions.
Bottom line
Fake IW329062 watches get caught in the details, not on the logo. Specs, finishing, movement behavior, and paperwork consistency do the work. Decide before you buy whether you are shopping for a genuine watch or a replica, then hold the seller to the standard that matches. Mixing the two is how people lose money.
