Answer
IW938249 is not a reference number in the IWC Schaffhausen catalog. IWC reference numbers use the letters IW followed by six digits, for example IW377714 or IW500705. The IWC catalog lists those numbers with a model name, case size, and movement. IW938249 does not appear there. On replica seller sites the same string appears as a listing code. It points to one SKU in one seller's inventory, not to a watch that IWC made.
How the code is built
The string copies IWC format: two letters, six digits. Replica sellers reuse that format so a listing reads like a factory reference. Two listings with the same code on two sites can show two different watches. Case size, dial color, and strap change from seller to seller. The code is a seller label, so it carries no spec on its own.
What the listing shows
- Case: 41 mm to 44 mm steel, sometimes two-tone
- Movement: 21,600 to 28,800 vph automatic, or quartz at the low tiers
- Crystal: mineral glass at low tiers, sapphire at mid tiers
- Water resistance: printed 30 m to 100 m, tested in few cases
- Price: $60 to $400, tracking movement and case finish
How to read a spec sheet
Ask for four photos: dial at 12, caseback engraving, crown side, and clasp. Ask for a movement photo with the rotor visible. A seller who sends stock images has no watch in hand. Ask for caliper readings on case diameter and lug width. Numbers that match the listing are a check on the build.
Movement tiers
Three tiers appear in this price range. Quartz movements cost the least and tick once per second. Low-grade automatic movements run at 21,600 vph. Clones of the ETA 2824 or the Sellita SW200 run at 28,800 vph and a local watchmaker can service them. Movement grade moves the price more than any other part.
Legal and shipping facts
In the United States, trafficking in counterfeit goods is a federal crime under 18 U.S.C. 2320. US Customs and Border Protection seizes counterfeit watches at ports and mail hubs. A seized package is not returned, and the carrier gives the buyer no refund path. Payment methods with no chargeback, such as gift cards or direct bank transfer, remove the buyer's last option.
Checks before buying
- Search the exact code plus "review" and read forum posts.
- Compare the caseback text with IWC photos of the closest real reference.
- Ask the seller for the movement name, not "Swiss movement."
- Get the return window in writing.
- Pay with a method that allows a dispute.
What is unknown
No public source ties IW938249 to a factory, a model, or a year. A page that names a factory for this code is guessing. Treat the code as an inventory label. Judge the watch on photos, movement, and seller terms.
