A replica IW323745 is a copy of an IWC Ingenieur reference, so judge it the way you would judge the real watch: case geometry first, bracelet integration second, dial print third, movement last. Photos hide the two things that matter most, which are case thickness and how the bracelet meets the lugs. Ask for measurements and a side profile shot before you commit. Confirm the genuine reference specs on IWC's own reference page so you know what the copy is supposed to match.

Prerequisites

  • The exact reference number you want, written down, including the case metal and dial color
  • Published case diameter, thickness, and lug width for that reference
  • A caliper or a seller willing to measure the watch
  • Written return terms in the listing or chat log

How to vet the watch

  1. Open the official IWC reference page and record case diameter, thickness, water resistance, and crystal type.
  2. Ask the seller for caliper readings of diameter and thickness, then compare them to your recorded numbers.
  3. Request a straight-on side photo so you can see case thickness against the bezel and caseback.
  4. Ask which movement is inside and whether it is a clone, a Miyota, or an ETA-style automatic.
  5. Request a macro photo of the dial at 12 and 6 to check index alignment, print weight, and date window cut.
  6. Check the bracelet end links for gaps against the case and confirm the clasp engraving depth.
  7. Ask whether the watch was pressure tested and to what rating before shipping.
  8. Confirm the return window and who pays return shipping in writing.

Where cheap copies fail

Thickness runs 1 to 2 mm over spec on most low-tier Ingenieur copies, which flattens the case profile. Bracelet end links sit proud of the case or rattle at the pivot. Dial print looks heavy under magnification, and the date window edge is sharp instead of beveled. Screw-down crowns often thread rough. A pressure test is the only way to know whether the stated water resistance is real, and most budget sellers skip it.

Legal position in the US

Counterfeit watches are restricted merchandise. US Customs can seize shipments, and selling copies as genuine exposes a seller to trademark claims and consumer protection action. Buy only with a stated replica description and keep the transaction record.
