The short answer: a good fake Portugieser Small Seconds gets the 40.4 mm case, the small seconds subdial at 6 o'clock, and the leaf hands right. What separates a $120 copy from a $400 one is almost always the movement, the thickness that movement forces on the case, and how the subdial is finished. If a seller cannot tell you what is ticking inside, that silence is your answer.

Start With the Real Watch

Most people mean the Portugieser Automatic 40 when they say "small seconds." IWC builds it around calibre 82200, a Pellaton-wound automatic with a 60-hour reserve running at 4 Hz. The case is 40.4 mm across, roughly 10.8 mm thick, and the dial carries a single subdial at 6 with no date. Anything a replica does has to be measured against those numbers, because they are the ones you can check with a caliper in ten seconds.

The Movement Is the Whole Story

Genuine 82200 is in-house and finished to a standard no Chinese factory matches. Replicas go one of three routes:

  • A decorated clone movement, sold as a "custom 82200." This is the top tier. Cotes de Geneve stripes, blued screws, and a rotor engraved to look like the real thing.
  • A Japanese automatic with a piggyback subdial module. Reliable and easy to service, but the module stacks on top of the base movement and pushes the case 1 to 1.5 mm thicker than spec.
  • A cheap Chinese automatic. Runs, keeps poor time, and often sounds like a coin in a tin can when you shake it.

The module is why so many fakes sit at 12 mm or more. On the wrist that reads as a chunky watch, and the Portugieser is not a chunky watch. It is a dress piece with long, slender lugs. Thickness is the tell I notice first, before I look at the dial.

Dial Details Worth Zooming In On

I look at the subdial first. On the real thing the small seconds ring is snailed, with fine concentric texture you can see in raking light. Cheap copies print a flat circle and call it done. The seconds hand should reach the printed track, not stop short of it.

Then the applied numerals. They should be polished, faceted on the edges, and sit at a consistent height. Laser-cut flat numerals look dull from an angle. The leaf hands are harder to fake than people expect; the curve and the polish either catch light properly or they do not.

Printing matters too. Look at the weight of the lettering and the spacing between words. Slightly bold, slightly blurry text is the most common flaw on mid-tier copies. And check the crystal: anti-reflective coating should be subtle. A strong blue or purple wash under office lighting is a giveaway, since the original coating is nearly invisible.

Case, Crown, and Caseback

The crown should be conical, signed, and firm when you set it. A wobbly crown with a soft click is a bad sign. Lug width is 20 mm, and the lug edges should be crisp rather than rounded off by polishing. On the back, the sapphire should show a rotor with correct engraving and a movement that looks assembled rather than stamped.

Straps are usually the weakest link out of the box. Most sellers ship a stiff alligator-pattern leather. A decent aftermarket strap in the right color will do more for the look than any other $40 you spend.

What Each Price Tier Buys

  1. Under $150: wrong thickness, flat subdial, rough printing. Fine as a curiosity, not as something you would hand to a friend.
  2. $200 to $300: a real automatic, decent dial, and the thickness problem. This is where most buyers land.
  3. $350 to $500: the top tier from the better factories. Case profile, dial printing, and movement decoration all get noticeably closer.
  4. Above $500: diminishing returns. You are paying for scarcity, not accuracy.

The Honest Limits

A replica is not a genuine IWC and never will be. It does not hold value, service is awkward because many watchmakers will not touch it and parts are not standardized, and any water resistance claim should be treated as marketing. Customs in some countries seize counterfeit watches, and selling one as genuine is fraud. Buy it as a fun object with clear eyes about what it is.

Quick Pre-Purchase Checklist

  • Ask for the case thickness in millimeters, measured, not quoted.
  • Ask which movement, by name, and for a photo of the caseback.
  • Request a macro shot of the subdial in raking light.
  • Check that the seller takes returns and accepts a payment method with buyer protection.
  • Confirm the strap size is 20 mm so you can swap it easily.
