What is IW329020?

IW329020 is a reference number that appears in some replica watch listings. IWC Schaffhausen does not list IW329020 on its current website. Genuine IWC references in the 3290 family include IW329001, IW329002, and IW329003. Those are Aquatimer Automatic 42 mm watches. If a seller claims an IW329020, ask for the reference number on the caseback. Compare it to IWC's official records. A genuine IWC has a unique serial number and a matching reference number.

Common tells of a fake IW329020

  • Case finishing: Genuine IWC cases have sharp edges and even brushing. Fakes often have rounded lugs and polished areas that should be brushed.
  • Dial printing: The IWC logo and "Automatic" text are crisp. Fakes have fuzzy text, wrong font, or thick ink.
  • Lume: Genuine Super-LumiNova glows bright green or blue. Fakes glow weak and fade in minutes.
  • Bezel: The genuine bezel clicks with a firm feel at 60 positions. Fake bezels feel loose or have backplay.
  • Crown: The genuine crown has fine threads and screws down without grit. Fake crowns cross-thread or feel gritty.
  • Caseback: Genuine engraving is deep and sharp. Fakes have shallow laser etching or wrong font.
  • Movement: Genuine calibre 30120 is a modified ETA 2892. Fakes use cheap Chinese or Japanese movements. Look at the rotor engraving and finishing.
  • Weight: A genuine steel Aquatimer weighs about 180 g with a bracelet. Fakes often weigh less than 150 g.
  • Bracelet: Genuine bracelet screws have flat heads and fit flush. Fake screws strip or protrude.
  • Price: A genuine Aquatimer Automatic 42 mm sells for $4,000 to $6,000 used. A new fake costs $200 to $500. If the price is too low, it is a fake.

How to verify an IW329020

  1. Ask the seller for a photo of the caseback with the reference and serial number.
  2. Check the reference number against IWC's official catalog or an authorized dealer.
  3. Ask for the original box, papers, and warranty card. Genuine IWC papers have a matching serial number.
  4. Take the watch to a watchmaker. Ask them to open the caseback and inspect the movement.
  5. Use a magnet test. A genuine IWC is not magnetic. A fake with a cheap steel case may attract a magnet.
  6. Check the date change. A genuine IWC changes date at midnight with a crisp snap. Fakes change at the wrong time or not at all.

What to do if you bought a fake IW329020

If you bought a fake IW329020, contact the seller and your payment provider. File a dispute if you used PayPal or a credit card. Report the listing to the platform. Do not send the watch back until you have a written agreement. Keep all messages and photos. If the seller used a fake reference number, that is evidence of fraud.
