The short answer: buy a fake IW329087 only as a replica, not as an investment, and only from a seller who shows clear photos of the actual watch, states the movement and case size, and offers a return window. If the listing uses factory stock images, hides the caseback, or refuses a video, stop. The IW329087 sits in IWC's Aquatimer family, so the replica should match the original's case shape, internal bezel layout, dial printing, and strap fit. A low price is not a win if the watch arrives with a misaligned bezel or a quartz movement.

What to look for in a fake IW329087

Judge the replica as a watch first and a copy second. The reference has a diver-style case and an internal rotating bezel, so small geometry errors are easy to see on the wrist.

  • Case and crown guards. Compare the lug shape, bezel edge, crown guard profile, and caseback engraving with official photos. The finish should be brushed on the case sides and polished only where the original is polished.
  • Dial and date. Check the font weight, index alignment, date window position, and hand length. Printing should be crisp at 10x magnification, not fuzzy. The date should sit square in the window.
  • Internal bezel. The bezel should turn with firm, even steps and return to 12 without slack. Misalignment at 12 is a common replica flaw.
  • Movement. This reference is an automatic in the original. A quartz movement is a clear downgrade. Ask for a movement photo and a short video showing the seconds hand sweep, date change, and crown action.
  • Strap and clasp. The strap should fit the lugs without gaps. Check buckle engraving, spring bar access, and whether the rubber feels stiff or chalky.
  • Water resistance. Treat any claim as unproven. A replica is not a dive watch unless a watchmaker pressure tests it.

Parameter bands that matter

Use these bands as a checklist, not a guarantee. Ask the seller to measure the actual watch.

  • Case size: within about 0.5 mm of the published reference size. For this Aquatimer-style case, most buyers should expect a 42 mm class watch. A 40 mm or 44 mm case changes the wrist presence.
  • Thickness: close to the original's published thickness. A thick case often means a low-grade movement or a spacer.
  • Lug width: match the strap size. Do not accept a seller who says a 21 mm strap fits a 22 mm lug gap.
  • Bezel action: firm detents, no back play, clean alignment at 12.
  • Timekeeping: within about 20 seconds per day on a timegrapher is a reasonable target for a clone automatic. Ask for the reading.
  • Lume: even color and a clean edge. Uneven lume is a visible tell in low light.

Common pitfalls

Most bad buys come from weak seller checks, not from one obvious cosmetic flaw.

  • Stock photos only. If the seller will not send a timestamped macro photo, you are buying a promise.
  • 1:1 claims. This phrase has no standard. Ask for measurements and video instead.
  • No movement photo. A closed caseback is not proof of an automatic movement.
  • No return window. A replica with a misaligned bezel or a dead movement is your problem without returns.
  • Pressure claims. Waterproof in a listing is marketing. Seals and cases vary.
  • Customs and shipping risk. Understand the seller's policy before paying. Do not rely on a chat promise.
  • Paperwork packages. Boxes and cards do not make a replica genuine. Pay for the watch, not the props.

FAQ

Is a fake IW329087 worth buying?

It can be worth it if you want the Aquatimer look and accept replica compromises. It is not worth it as an investment, and it is not worth it from a seller who will not show the actual watch.

How do I spot a poor replica IW329087?

Look for a misaligned internal bezel, fuzzy dial print, a date that sits off-center, a stuttering seconds hand, and a caseback with shallow engraving. These are visible before you need a loupe.

Should I wear a replica IW329087 in water?

No, not unless a watchmaker has pressure tested it and you accept the risk. Even then, rinse it in fresh water after contact with salt water or chlorine.

What should I ask before paying?

  1. Can you send a timestamped photo of the actual watch, including the caseback and movement?
  2. What is the measured case diameter, thickness, and lug width?
  3. What movement is inside, and what is the timegrapher reading?
  4. What is the return window, and who pays return shipping?
  5. How is the watch packed, and what happens if customs seizes it?

A good fake IW329087 is a cosmetic watch. Buy the seller's evidence, not the listing copy.
