Fake IW329067: The Short Answer

A counterfeit IW329067 fails in four places: the caseback engraving, the dial furniture, the movement markings, and the paperwork that travels with the watch. Work those four checks in order and most replicas fall apart before the third one. Budget about fifteen minutes and a jeweler's loupe.

What Reference IW329067 Should Be

Reference numbers in the IW3290 block belong to IWC's Aquatimer Automatic family. A genuine watch carries one reference number stamped on the caseback, and every other detail on the watch has to match the model IWC cataloged under that number. Replica sellers often pair a real reference with a dial, bezel, or hand set borrowed from a different generation. That mismatch is the easiest problem to catch and the hardest one for a counterfeiter to hide.

Before You Start

  • A 10x jeweler's loupe
  • Digital calipers or a steel ruler
  • High resolution photos of the caseback, dial, clasp, and crown
  • The published specs for the reference: case diameter, thickness, lug width, movement type

Step-by-Step Checks on the Case and Dial

  1. Study the caseback engraving under the loupe and confirm the text is cut into the metal, not printed on top of it.
  2. Measure the case diameter, lug width, and thickness with calipers, then compare those numbers to the published specs for the reference.
  3. Turn the bezel through a full rotation and listen for even, indexed clicks with no side play.
  4. Examine the dial printing at 10x magnification and check that the logo, model text, and depth rating sit on one plane with sharp edges and no ink bleed.
  5. Inspect the date window for centered numerals, correct font weight, and a clean aperture.
  6. Hold the watch at an angle under a lamp and confirm the lume plots are level, uniform in color, and free of overflow onto the dial.

Movement and Serial Checks

  1. Open the caseback only if you own the watch or the seller agrees to it in writing before the sale.
  2. Check the finishing on the rotor and bridges for Geneva stripes, perlage, and engraving that follows the curvature of the part.
  3. Photograph the serial number at high magnification and confirm the digits are struck sharp and straight rather than dot matrix printed.
  4. Send the serial and reference to an IWC service center or authorized dealer and request written confirmation.

Papers, Price, and Seller Behavior

  1. Compare the warranty card, booklet, and box printing against the reference and the production year.
  2. Ask for the original purchase date and the name of the dealer who sold it.
  3. Check the asking price against recent sold listings for the same reference in comparable condition.
  4. Walk away from any seller who refuses a clear photo of the serial or pushes for a fast wire transfer.

If the Watch Fails a Check

Stop the transaction and put the finding in writing to the seller. Report the listing to the platform with your photos attached. If money has already changed hands, open a dispute with your payment provider and include the serial photos, the measurement discrepancies, and any refusal by the seller to allow inspection. Keep every message.
