Short answer
IW329117 is an IWC reference number. IWC uses the format IW plus six digits. The leading digits mark a case family. The trailing digits mark a dial, strap, or market variant inside that family. I could not confirm IW329117 against IWC's public catalog. That means the case diameter, dial color, and movement for this exact reference need to come from IWC records or an authorized dealer. A seller who lists specs without a source is guessing.
Replicas are sold under this reference number. Build quality changes by factory and by batch. Two watches with the same listing title can differ in movement, case finish, and dial print.
How IWC reference numbers work
IWC groups references by case family, then separates versions with the last digits. A listing that shows IW329117 and nothing else is incomplete. Ask for case diameter in millimeters, case thickness, lug width, and movement caliber. Those four numbers decide most of the value.
Specs to verify before buying
- Case diameter and thickness. Measure with calipers. Listing text is not a measurement.
- Case material. Steel is standard. Titanium and bronze versions weigh less and cost more.
- Dial print. Check the logo, the minute track, and the text block under 12.
- Hands and lume. IWC uses Super-LumiNova. Replica dials often use a weaker compound with a shorter glow.
- Crown threads. A screw-down crown should engage in 2 to 3 turns with no grit.
- Crystal. Sapphire with anti-reflective coating on both sides is the baseline at this tier.
- Water resistance. Many replicas test to 3 bar. Genuine dive-rated IWC cases test far higher.
- Bracelet end links and clasp codes. Mismatched stamps are a common flaw.
Movements seen in replica IWC watches
Three calibers cover most of the market: Sellita SW200-1, ETA 2824-2 or 2892-A2, and Miyota 9015. The SW200-1 is a 26-jewel automatic with a 38-hour power reserve. The Miyota 9015 is 24 jewels with a 42-hour reserve. A Swiss movement claim needs a photo of the rotor and the balance cock. Without a photo, treat the claim as unknown.
Price tiers
Wholesale replica pricing sits in three bands. Entry tier runs about $80 to $150. Mid tier runs $200 to $400. High tier runs $450 to $900. Movement grade, case finishing, and dial print separate the bands. Price alone does not prove quality.
Legal and inspection notes
Counterfeit watches are illegal to import into the United States. US Customs and Border Protection seizes shipments of counterfeit goods. A replica carries no IWC warranty and no IWC service support. Before payment, ask for dated photos of the actual watch, a timegrapher readout, and the return policy.
