The short answer
A fake IW328020 is a replica of an IWC reference sold under labels like "first copy," "1:1," "AAA," or "super clone." Expect to pay anywhere from about $90 to $650 depending on tier. None of them contain an IWC movement. The good ones use a Miyota 9015, a Sellita/A2892 clone, or a decorated Seagull, and the bad ones use a $12 quartz or a rough 21-jewel automatic that will drift minutes a day within a year. If you want the watch for how it looks on your wrist, the top tier can be convincing at arm's length. If you want it for what it is, buy the real thing or a good homage.
What the tiers actually mean
Sellers love vague grading. Here is how I sort them in practice.
- Under $120. Stamped or poorly milled case, mineral glass, printed dial that looks flat under light, sharp-edged bracelet, no meaningful water resistance. Sizing pins strip. Skip it.
- $150 to $280. Proper 316L case with decent brushing, sapphire crystal, a clone automatic. Date font and hand finishing are usually where it falls apart.
- $350 to $650. The "super clone" bracket. Correct case profile, AR coating on both sides of the crystal, applied indices with clean lume fill, a decorated movement, sometimes a cloned bracelet clasp with the right micro-adjust. This is the only tier worth arguing about.
One honest note: the price ladder has almost nothing to do with the reference number. Factories reuse the same case and dial blanks across several models, so a fake IW328020 from the same factory as a fake of another IWC often shares parts.
Start with the spec sheet, not the photos
Pull the genuine dimensions from IWC's own product page for the reference: case diameter, thickness, lug width, crystal type, water resistance, movement calibre. Then measure. Replica cases are routinely 0.3 to 1.2mm thicker than the real thing because the movement spacer and caseback gasket stack differently. Thickness is the tell most people never check, and it changes how the watch sits under a cuff.
Weight is the second one. A genuine steel case of that size and a clone case of the same size should land within a few grams. If a seller quotes a weight that is 20g light, the case is thinner-walled or the bracelet is hollow-linked.
The tells I look for first
- Dial printing. Genuine IWC text is crisp with clean apertures in the letters. Fakes blow out the thin strokes and the text sits slightly proud of the dial, so it casts a shadow at a low angle.
- Applied indices. Look at the edges. Real ones are polished on all sides. Cheap ones show a stamped edge and lume that sits below the frame rim.
- Hands. Hand-polished bevels catch light in a continuous line. Painted or laser-cut hands go dull in the middle.
- Date wheel. Font weight and centering in the window. This is where most mid-tier fakes are obvious.
- Crown engraving. Should be deep and clean, not shallow and fuzzy. Check the crown tube threads, not just the cap.
- Caseback. Engraving depth and the reference and serial font. Compare against a real photo at the same magnification.
- Bracelet and clasp. Taper, link edge chamfer, clasp logo stamping, and whether the end links sit flush against the case with no gap.
Movement reality
Ask directly: what calibre is inside, what is the beat rate, and what is the power reserve? A real answer takes ten seconds. "Swiss movement" with no name is marketing. Most of these run at 28,800 vph and give 38 to 42 hours. Anything claiming the IWC power reserve figure on a $250 watch is not telling you the truth. Also ask for a timegrapher photo showing rate, amplitude, and beat error before shipping. A decent seller has one on file.
Water resistance and the warranty question
Treat any claimed depth rating as fiction unless the case was pressure tested. Gaskets on replicas are the first thing to fail, and a swim is how people find out. Get it tested locally if you plan to wear it near water. On warranty: there is none worth relying on. A "one year factory warranty" from an overseas seller means you ship it back at your cost and hope.
Before you pay
- Ask for dated photos with a handwritten note, not stock images.
- Get the measurement numbers in writing: case, thickness, lug width, weight.
- Pay by a method with buyer protection. Bank transfer and crypto have none.
- Ask which factory and which batch. Batch matters more than the listing.
- Know your import rules. Counterfeit goods get seized and destroyed at the border, and you have no recourse.
Bottom line
A top-tier fake IW328020 will fool most people across a table. It will not fool a loupe, a scale, or a caliper, and it will not hold value. Buy it as a costume if that is what you want. Just go in knowing which of those three things you are paying for.
