Short answer
IW329012 is an IWC reference number in the 3290 block. IWC used the 3290 block for the Aquatimer Automatic, a steel dive watch with a 42 mm case and a 300 m water resistance rating. IWC does not publish a separate spec page for every code in an old block, so confirm the dial, bracelet, and movement with IWC or an authorized dealer first. Replica sellers attach reference numbers to listings that do not match the original watch.
What the original is
- Case: 42 mm steel, unidirectional rotating bezel.
- Water resistance: 300 m on the catalog sheet.
- Movement: IWC caliber 30120, a modified Sellita SW300-1, 42 hours of power reserve.
- Crystal: sapphire with anti-reflective coating on both faces.
- Strap: rubber or steel bracelet, per code suffix.
Those numbers come from the Aquatimer Automatic spec sheets IWC published from 2014 onward. A listing that shows a 36 mm case or a 100 m rating is not IW329012.
What replica versions include
Most replica IW329012 listings use a 42 mm steel case and a closed caseback. Movements are Asian automatic copies: Seagull ST2130, Miyota 9015, or a Sellita SW200 clone. Beat rate is 28,800 vph on the Miyota and Sellita copies, 21,600 vph on some Seagull builds. Power reserve runs 38 to 42 hours. Case thickness lands between 13 mm and 15 mm against 14 mm on the original. Weight with a steel bracelet is 150 g to 180 g.
Price bands
- $80 to $150: mineral glass, stamped clasp, 21,600 vph movement, lume that fades inside an hour.
- $150 to $350: sapphire crystal, screw-down crown, 28,800 vph movement, solid end links.
- $350 to $600: copied movement bridges, tighter bezel action, cleaner dial print.
Checks before you pay
- Measure the case. 42 mm across, not 40 mm.
- Ask for the movement name and beat rate. 28,800 vph equals 8 beats per second.
- Ask for a water resistance test result. Most replicas hold 30 m to 50 m, not 300 m. Do not dive with one.
- Inspect dial print under 10x magnification. Replica text has soft edges and wrong font weight.
- Check the date window position and date font.
- Confirm the return policy and the payment method in writing.
Legal position in the US
US Customs and Border Protection can seize and destroy counterfeit watches at import. 19 U.S.C. 1526 covers trademark violations on imported goods. 18 U.S.C. 2320 covers trafficking in counterfeit marks. Buying one replica for personal use is not the same charge as selling, but the seizure risk stays with the parcel. A seller who lists a replica as genuine IWC is exposed to trademark claims. Resale prices for the genuine watch depend on condition, box, and papers; check current secondary market listings for that figure.
