What is a fake Portugieser 40mm?
A fake Portugieser 40mm is a replica of the IWC Portugieser Automatic 40, a dress watch with a 40.4 mm case and a small seconds subdial at 6 o'clock. Replicas copy that dial layout and case size, then swap in third-party movements and lower-cost finishing. The genuine watch uses IWC's in-house calibre 82200 with 60 hours of power reserve.
How close is the case size to the real thing?
The original measures 40.4 mm across and 12.3 mm thick, with a 20 mm lug width. Most replicas hold the 40 mm diameter but add 1 to 2 mm of height because the movement sits in a thicker spacer. Case thickness is the single easiest tell in a side-by-side look.

Weight is the second clue. Genuine cases are machined from steel or precious metal with tight tolerances, so a replica often feels light or slightly hollow on the wrist.
Which movement does a replica use?
Most copies run a Miyota 9015, a Seagull ST series, or a generic clone with the rotor engraved to look like the 82200. Genuine Pellaton winding is a two-way ratchet system, while Miyota-based copies wind in one direction.
Accuracy matters less than feel. A well-tuned Miyota can keep good time, but the winding action, rotor noise, and power reserve usually differ from the original.
What separates a good copy from a poor one?
- Dial printing: crisp thin numerals with no bleeding under magnification.
- Applied indices: genuine markers are polished and set level, not glued at an angle.
- Small seconds hand: shaped and heat-blued or silvered to match the reference.
- Crystal: sapphire with anti-reflective coating on both faces.
- Caseback engraving: deep, even lettering instead of shallow laser marks.
- Strap and buckle: alligator-grain leather with a signed, correctly sized buckle.
What should you check before buying?
- Ask for the measured thickness and lug-to-lug distance.
- Request close-up photos of the subdial and dial text.
- Confirm the crystal material and coating.
- Check photos of the caseback and crown engraving.
- Ask which movement is inside and who services it.
Does a 40 mm Portugieser suit smaller wrists?
Yes. The 40.4 mm case with slim bezels wears larger than the number suggests, so it fits wrists from roughly 6.5 inches upward. A thicker replica case pushes the watch higher off the wrist, which changes how the lugs sit.
Try a 40 mm dress watch locally before ordering. Fit depends more on lug shape and curvature than on diameter alone.
Is a replica the same as a counterfeit?
Both describe a watch made to imitate a branded model without authorization. Buying or reselling one as genuine is fraud, and the category sits in a legal gray zone in many countries. Treat any purchase as a novelty item, not an investment.
