What IW329091 refers to
IW329091 is an IWC reference number. The IW3290 block is where IWC places Aquatimer Automatic 42 mm references. Those watches are dive models with 300 m water resistance, an inner rotating bezel, and a 42 mm steel case. Published spec sheets for the exact suffix 091 are thin. Check the caseback engraving against the brand's own documentation before you treat a listing as accurate.
What "replica" and "first copy" mean
Both words describe a watch built to look like a branded model without a licence from the brand. Sellers rank them by cosmetic accuracy and use labels like "first copy", "1:1" and "mirror". Those labels are marketing terms. No standards body defines them. No grade changes the legal status of the item.
- Case: 316L steel is common. Weight and lug finishing vary by grade.
- Dial: printed indices. Lume quality is the usual weak point.
- Movement: imported automatic or quartz. Parts do not match the original, so service is hard.
- Crystal: sapphire on higher grades, mineral glass on cheaper ones.
Genuine versus copy
A genuine Aquatimer carries a manufacture calibre, a serialised warranty, and water resistance tested to 300 m. A replica copies the outside of the case. It does not carry the same movement, the same tolerances, or a valid warranty. A depth rating printed on a replica has no pressure test behind it. Do not dive with one. Resale also differs: the genuine watch holds part of its value, the copy has no resale market.
Legal status in the US
Trafficking in counterfeit goods is a federal offence under 18 U.S.C. § 2320. US Customs and Border Protection seizes counterfeit watches at ports of entry and states that importing counterfeits for personal use breaks customs law. Sellers inside the US who ship counterfeits face seizure and civil penalties. Marketplaces and payment processors pull listings when the trademark owner files a complaint.
Checks before paying
- Ask for a photo of the caseback engraving. Compare it to brand photos.
- Ask which movement sits inside. "Clone" often means an unbranded Asian automatic.
- Ask for close-ups of the clasp code and the crown thread.
- Confirm the return address. Offshore-only returns leave no recourse.
- Pay by a method with chargeback rights. Wire transfer does not.
Price context: a new IWC Aquatimer Automatic lists near $6,000 to $7,500 depending on the version. Replica listings for this reference sit in the $150 to $600 range.
