A fake IW323797 is a replica of an IWC watch built on the IW323797 case reference. The reference is a case code IWC engraves on the back and logs in its own records, and any workshop can stamp it. Judge the watch by the case geometry, dial printing, movement finish, bracelet fit and the seller's paperwork, not by the digits on the back. A replica that matches the genuine case dimensions and the genuine dial is a different product from one built from stock parts with a laser-etched code.

What to gather before you evaluate one

  • Two or more sharp photos of the genuine IW323797 from different angles, including the case back
  • A 10x loupe
  • Digital calipers and a gram scale
  • The seller's return policy in writing, with a deadline

Check the case and the reference engraving

  1. Request a close photo of the case back before you pay, taken straight on with no glare.
  2. Compare the depth and letter spacing of the IW323797 engraving against a photo of a genuine example, since shallow laser etching with wide spacing is the most common failure.
  3. Measure the case diameter and thickness with calipers and compare both figures to IWC's published specification.
  4. Weigh the bare case head and compare it to a genuine weight for the same reference and metal.
  5. Check the lugs and crown guards for tool marks, uneven bevels and polishing that runs over an edge.

Inspect the dial under magnification

  1. Look at how the applied indices sit, because genuine markers are set flush with even gaps and replicas often sit high on one side.
  2. Read the brand and model text under the loupe and check stroke weight, spacing and the crispness of the edges.
  3. Check the date window for a squared frame, correct magnification and a disc that sits level behind the aperture.
  4. Compare hand length and finish against the genuine reference, since oversized hands and brushed instead of polished bevels are frequent tells.

Examine the movement

  1. Ask for a movement photo through an exhibition back, or decline the deal if the seller will not supply one.
  2. Compare rotor engraving, jewel count and bridge finishing to the genuine caliber for this reference.
  3. Confirm the beat rate with a timegrapher, since 28,800 vph and 21,600 vph are easy to tell apart and cheap replicas often run the lower figure.
  4. Check the winding feel and the crown action for grit or a loose stem.

Check the bracelet and clasp

  1. Flex the bracelet and look for gaps at the end links where they meet the case.
  2. Compare clasp engraving and the shape of the folding mechanism to a genuine photo.
  3. Confirm whether the links are screwed or pinned and match that to the reference.

Red flags worth walking away from

  • Stock catalog photos only, with no image of the actual watch
  • A price far under the secondary market for the genuine reference
  • Claims of Swiss origin with no movement photos and no service history
  • No written return window, or pressure to pay off-platform
  • Papers and box that do not match the reference on the case back

Legal position in the United States

Selling a replica as a genuine watch is trademark counterfeiting and fraud, and US Customs seizes counterfeit watches at the border. Personal import of a counterfeit watch can also result in forfeiture. Treat any replica purchase as a knowingly gray transaction with no manufacturer support, no warranty and no resale value as an IWC.
