Quick answer
IW323750 is not a reference number that appears in IWC Schaffhausen catalogs. The "IW" prefix plus six digits follows IWC's own format. The 3237 block belongs to the Aquatimer Automatic family, a dive watch line. Sellers use codes like IW323750 to label copies of that family. The watch in those listings is a counterfeit, not a factory second or surplus genuine piece.
How IWC reference numbers work
IWC stamps "IW" plus six digits on casebacks and papers. The first four digits name the family. The last two mark the dial, case metal, or strap variant. A steel Aquatimer Automatic from around 2009 carries a code in the 3237 range. IWC publishes current references on its own site. If a code does not appear there, treat it as unverified.
I cannot confirm IW323750 as a catalogued variant. It may be a seller's internal code, a discontinued variant, or a number invented for a listing. Ask the seller for a caseback photo and an IWC service record. Most will not have either.
What the genuine Aquatimer is
- IWC was founded in Schaffhausen, Switzerland, in 1868.
- The Aquatimer line started in 1967 and is IWC's dive watch family.
- Steel Aquatimer Automatics measure about 42 mm across and use an automatic movement built on a third-party ebauche.
- Caseback engraving, crown threads, and the inner rotating bezel are the parts counterfeiters miss.
Specifications change by variant. Confirm any number against IWC's published data before you rely on it.
Where replica listings appear
Listings for replica IW323750 show up on independent sites, social media accounts, and marketplaces. Prices for high end copies land between about $200 and $600. Sellers describe movements as Swiss, Japanese, or clone. None of those labels carries a guarantee. Photos in listings are often of a genuine watch.
Legal status in the United States
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. § 2320. Penalties include prison time and fines. Selling a counterfeit watch also exposes the seller to civil suits under the Lanham Act, 15 U.S.C. § 1114. US Customs and Border Protection seizes counterfeit shipments and destroys them. Buyers can lose both the money and the item.
Practical risks
- No warranty and no service from IWC. Brand service centers refuse counterfeit watches.
- Water resistance is not tested. A dive watch copy can leak in a sink.
- Case metals are often plated brass or low grade steel. Plating wears through.
- Resale value is near zero. Genuine watches hold value. Copies do not.
- Payment methods are hard to reverse. Chargeback options are limited.
How to check a reference number
- Search the code on IWC's official site.
- Compare the caseback engraving with archive photos of the same reference.
- Ask for a service invoice from an authorized center.
- Check the serial against the reference in IWC records, if the seller provides one.
If a seller cannot supply those items, the number on the listing is decoration.
