Quick answer
IW323750 is an IWC Schaffhausen reference number. Replica sellers put it in listing titles to signal which original they copied. A watch sold under that label is not an IWC product. It has no manufacturer warranty, no service record, and no IWC parts. Prices for these replicas run from about $80 to $600. Movement claims in that range need photo proof, not a spec sheet.
Match the exact model before paying. IWC reference numbers identify case, dial, bracelet and movement combinations, and IWC does not publish a full public cross-reference. Confirm case shape, diameter, dial layout and production years against IWC records or a dealer who handles the brand. If a listing shows IW323750 with a dial you cannot find on a real IWC, treat the number as decoration.
What the reference number covers
IWC reuses a base number across variants. A suffix change can mean a different dial color, a different strap, or a different movement. Sellers copy the string, not the logic. Two listings with the same IW323750 can describe two different watches.
Movement tiers
- Entry: Chinese copy of an ETA 2824 or a Miyota 8215, about $80 to $150.
- Mid: Seagull ST21 or a Hangzhou 6-series, about $150 to $300.
- Top: claimed Swiss ETA or Sellita SW200, about $300 to $600.
ETA and its parent Swatch Group cut third-party ebauche supply after 2011 and phased it out by 2020. A new Swiss ETA inside a $250 replica would come from old stock. The odds are low. Ask for a movement photo with the rotor off.
Common tells
- Date window font and alignment. Real IWC printing stays sharp at 10x magnification.
- Dial text weight. Replica "Schaffhausen" often sits heavier or closer to the edge.
- Anti-reflective coating. One side on many replicas, both sides on most originals.
- Bracelet end links. Gaps at the lugs show in photos taken at an angle.
- Rotor engraving depth. Laser marks look flat under light.
- Crown threads. Gritty engagement after 20 turns.
Water resistance
Do not swim with a replica. Gaskets are unverified. A pressure test at a local shop costs about $10 and tells you more than a "100m" claim in a listing.
Service and parts
No IWC service center will touch a counterfeit, and some will not return it. Independent watchmakers can fit generic gaskets, crowns and crystals. Case parts, dials and hands built for the copied model often do not fit the copy.
Legal position in the United States
Importing or selling a counterfeit watch violates 19 U.S.C. § 1526 and 18 U.S.C. § 2320. CBP seizes shipments and can fine the recipient. Personal use carries lower risk than resale. Resale is a federal offense with penalties up to 10 years.
Verify before paying
- Timestamped photos of the exact watch, not stock images.
- Movement photo plus a timegrapher reading.
- Case diameter measured with calipers.
- Refund terms in writing.
If a seller cannot supply these four items, the reference number in the title is the only part of the listing that was checked.
