The replica IW329080 is an unauthorized copy of the IWC Portugieser Automatic 40, a 40.4 mm steel dress watch with small seconds at 6 o'clock and the in-house calibre 82100. Copies sell for about $180 to $600 and run on third-party movements, most often a Miyota 9015, a Seagull ST automatic, or a Chinese clone with a decorated rotor. Case proportions and dial layout can land close to the original. The movement, the applied numerals, and the antireflective coating are where the price difference shows.
The genuine reference in numbers
- Case: 40.4 mm stainless steel, about 10.8 mm thick
- Movement: IWC calibre 82100, automatic, 60-hour power reserve
- Dial: applied Arabic numerals, leaf hands, small seconds subdial at 6
- Crystal: domed sapphire with antireflective coating on both faces
- Water resistance: 50 m
- Strap: alligator leather on a steel pin buckle
How to evaluate a replica IW329080 before paying
- Request a macro photo of the dial centered on 12. Check that the printed logo is sharp, sits level, and does not flake at the edges.
- Ask for a caliper shot across the case. Anything under 39.5 mm or over 41 mm is a different case set, not this reference.
- Confirm the movement by name and photo. A Miyota 9015 is a known quantity; a decorated clone needs a clear picture of the rotor and bridges.
- Look at the small seconds subdial. It should sit on the 12 to 6 axis, with a hand that sweeps without stutter at the tip.
- Ask for a side profile photo. Thin lugs and a domed crystal are the two features most often wrong on cheap builds.
- Check the caseback engraving depth and the crown signature in a close-up.
- Get the return window and the shipping method in writing before you send money.

Legal and shipping reality
Counterfeit watches carrying an active trademark infringe US trademark law, and US Customs and Border Protection can seize shipments at entry. Buyers have lost both the watch and the payment in those cases. Treat any purchase as unprotected, and expect no manufacturer service, no warranty, and no parts support on the movement.
