What replica iw323790 means
IW323790 is an IWC reference number in the Ingenieur Automatic family. The case family is IW3239: a 40 mm steel watch on a steel bracelet, sold by IWC from about 2013 to 2017. A replica of IW323790 is a third-party copy of that watch. The "-90" suffix does not appear in IWC's public listings for the main IW3239 references, so the dial color and bracelet type attached to that number need checking with the seller before payment.
Specs the original carries
- Case: 40 mm, stainless steel, sapphire crystal
- Movement: calibre 30110, automatic, about 42 hours of power reserve
- Water resistance: 120 m on the original spec sheet
- Bracelet: steel, integrated look, folding clasp
- Dial: baton hands, applied markers, date window at 3
These are the numbers a copy has to match. If a listing quotes a 42 mm case or a 38 hour reserve, the seller is describing a different watch.
Where replicas differ
Case thickness is the first tell. Copies often add 0.5 mm to 1.5 mm to fit a third-party movement. Bracelet end links are the second tell: the fit against the case is looser on copies, and the clasp engraving is shallow.
Dial printing is the third. On the original, the "IWC" and "Ingenieur" text sits at fixed heights above the date window. Copies misalign this by a fraction of a millimeter, and the date font is wider.
Movement is the fourth. A copy at the low end runs an Asian 2824 clone at 21,600 vph. The calibre 30110 in the original runs at 28,800 vph. Ask for a movement photo with the caseback off. A seller who refuses is selling a watch he has not inspected.
Price bands
Low band copies run USD 80 to 200. Mid band runs 250 to 450. High band runs 500 to 900 and claims a Swiss movement. Above that, the price stops matching the build. No copy holds resale value; the original IW3239 trades on the secondary market for a defined range and holds it.
Legal position in the US
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. § 2320. US Customs and Border Protection seizes counterfeit watches at ports of entry and destroys them. The buyer loses the money and the watch. This applies to watches shipped from overseas and to watches bought inside the US.
Checks before you buy

- Ask for the case diameter and thickness in millimeters, measured.
