Short answer

IW938124 does not appear in IWC public reference lists. No official IWC page, catalog, or auction archive ties that string to a production model. Listings that use it pair an IWC-style prefix with digits from another series. Treat the number as a seller label, not a factory code.

What the number looks like

IWC reference numbers start with IW and carry six digits. The leading digits group the family. IW37xxx covers Pilot models. IW50xxx covers Portugieser and Big Pilot. IW32xxx covers Aquatimer. The 938 block matches no family in current or past catalogs. Replica sellers recycle digit blocks to make a listing look unique.

Checks before you pay

  • Case back: ask for an engraving photo. Reference, serial, and case material should line up.
  • Movement: Asian 2824, Miyota 9015, and clone 3135 are the common base calibers. A seller who cannot name the movement is a risk.
  • Dimensions: request case diameter, lug width, and thickness in millimeters. Factory specs for comparable IWC models run 40 mm to 46 mm.
  • Crystal: sapphire with anti-reflective coating on both sides is the standard claim. Mineral glass is a downgrade.
  • Water resistance: 3 ATM is splash proof. Claims above 10 ATM need a pressure test.
  • Photos: ask for a timestamped shot. Stock images from other sellers are common.

Payment and shipping

Credit cards and PayPal offer chargeback rights. Bank transfer, gift cards, and crypto do not. US Customs can seize counterfeit goods. Buyers get a seizure notice and lose the watch. Resale of a counterfeit watch in the US carries civil penalties.

Price ranges

Listings for this reference string run from about $60 to $400. Price tracks movement grade, case finish, and crystal. A $60 quartz model and a $350 clone with a decorated automatic movement are different products. Neither is an IWC.

Terms to confirm in writing

Ask for the factory name, batch version, and warranty terms. Ask about return shipping if the watch fails a timing test. Timing outside plus or minus 20 seconds per day is a defect on most automatic movements.
