Short answer
IW938240 does not match the reference formats in IWC's public catalog. IWC lists models as IW37xxx, IW38xxx, IW50xxx and similar five-digit groups after the "IW" prefix. A search of IWC's own product pages returns no IW938240. Sellers who use that number may be using an internal code or an invented one. Ask for the actual model name before you pay.
What sellers list
Listings for a replica IW938240 repeat the same table: 41 mm case, stainless steel, sapphire crystal, automatic movement, 50 m water resistance, leather strap. Some listings say 42 mm and 100 m. The numbers change between sellers. None of them ship with a factory spec sheet.
Movement
Most replica watches at this tier run a Chinese automatic movement. Common families are Seagull ST and copies of the Miyota 9015. A genuine IWC in-house caliber does not appear in a replica at any normal price. A listing that claims an "IWC 69385 clone" is using a marketing label.
Case, dial, crystal
- Case: 316L stainless steel is standard. 904L is claimed but uncommon at this price.
- Crystal: sapphire with an anti-reflective coating on one or both sides.
- Dial: printed or applied indices. Applied indices cost more.
- Water resistance: 30 m to 50 m in practice. Do not swim with it.
How to check a listing
- Ask for the IWC model name, not the number.
- Request photos of the caseback, crown and clasp.
- Ask for a movement photo and a timegrapher reading.
- Confirm the return window in writing.
Price
Replica watches in this category sell for about $200 to $500. Payment above $600 for a steel automatic copy is hard to justify. Used genuine IWC watches in the same style sell for $3,000 and up.
Legal note
Counterfeit watches are illegal to sell in the United States and in most of the European Union. Customs can seize shipments. A buyer risks losing the payment with no recourse.
