IW323722: Short Answer

IW323722 is an IWC reference number. The IW3237 block covers Ingenieur Automatic models IWC sold in the 2010s. Replica sellers use this number for copies of the steel Ingenieur Automatic: round case, integrated bracelet, five screws in the bezel. The design is Gérald Genta's, from 1976.

IWC's own reference index is the source for case diameter, calibre number, and dial code. Public watch databases give different answers for IW3237 references. Check the number with IWC before you compare a replica to a listing photo.

Replica Build Facts

  • Case: 316L stainless steel is standard. Some listings claim 904L. No seller test report, no proof.
  • Size: copies run from 40 mm to 46 mm. Thickness runs 1 mm to 2 mm over the original when a clone movement sits in the case.
  • Crystal: sapphire with an inner anti-reflective coating at the mid and top tiers. Mineral glass below $100.
  • Movement: Asian clone of the ETA 2824, $180 to $320. Clone ETA 2892 or a Miyota 9015, $280 to $500. Quartz, $60 to $120.
  • Bracelet: solid links, push pins or screws. Hollow end links appear on cheap tiers.

Checks Before You Pay

  1. Bezel screws: five, slots set to the same radius. Crooked slots are common on low tiers.
  2. Date wheel: font and position. The window sits close to the dial edge on the original.
  3. Dial print: spacing of the brand lines and the logo. Ask for a 3x zoom photo.
  4. Crown: signed, and it should wind and set with no grit.
  5. Bracelet fit: end link gaps under 0.5 mm.
  6. Movement: ask for a timegrapher reading and a rotor photo.

Water, Service, Resale

Replica cases get a pressure test at the factory in most seller reports. Skip swimming and showers. Gaskets on these cases are not rated for 120 m even when the listing says so.

IWC will not service a counterfeit. Independent watchmakers will, at $120 to $250 for a clean and oil. Parts for clone ETA movements are easy to find. Parts for the case and bracelet are not.

Resale value is near zero. Watch groups, forums, and local watch shops ban sales of counterfeits.

US Customs and Law

US Customs and Border Protection can seize and destroy counterfeit watches under 19 U.S.C. 1526. The importer gets a seizure notice, not the watch. Repeat seizures carry fines. Trademark counterfeiting is a federal offense under the Lanham Act, 15 U.S.C. 1114.

The $800 de minimis rule covers duty, not counterfeit status. Small parcels still get X-rayed and opened.
