The short answer
A counterfeit Portofino Small Seconds gives itself away in three places before you ever open the case: the subdial hand, the printed text on the dial, and the engraving on the back. Those are the spots where cheap copies fail first, and they fail in ways you can see with a 10x loupe and no tools. If a watch survives all three, put it on a timegrapher or a beat-rate app. A real one ticks at 28,800 vibrations per hour. Most junk ticks at 21,600, and that gap is not something a seller can hide.

Know which Portofino you are looking at
Portofino is IWC's dress line, and the phrase "small seconds" gets used loosely in listings. The automatic versions in this family run IWC caliber 35111, a Sellita-based movement with a small seconds subdial at 6 o'clock and around 42 hours of power reserve. The larger hand-wound Portofino Eight Days uses caliber 59210 and adds a power reserve indicator near 8 o'clock. Cases on the automatics sit near 40 mm, with a slim bezel, short lugs, and an alligator strap. Pin down the reference number before you judge anything. A tell that matters on one reference means nothing on another.
Dial and hands
- Printing. The "IWC SCHAFFHAUSEN" line should be razor sharp. Copies bleed at the serifs, and the letter spacing drifts wider than the real thing.
- Subdial hand. It should be thin, tapered, and long enough to reach the printed track. Fakes use something stubby that stops short of the track and sits too high off the dial.
- Applied markers. Polished on every visible face, seated flat, no shadow gap underneath and no glue squeeze-out at the edges.
- Leaf hands. Crisp central ridge and a mirror finish. A grainy or wavy surface means plated steel, not polished steel.
- Dial finish. A sunburst should sweep evenly as you tilt the watch under a lamp. Orange-peel texture or patchy lacquer is a hard no.
Case, crown, and caseback
Look at where brushed surfaces meet polished ones. On the genuine watch those transitions are taped off and cut sharp, and the lug bevels catch light in a single clean line. Cheap copies blur the boundary or polish everything. The crown should be engraved with the IWC letters, sit flush against the case when screwed down, and turn without grit. On the caseback, check the reference number, the serial, the model name, and the "PROBUS SCAFUSIA" motto. Real engraving is deep and even. Laser-etched fakes look shallow and hazy under magnification. On gold references, check for hallmarks and look at the lugs for wear-through. Solid gold does not show a different-colored metal at the corners.
Movement checks
A beat-rate app on your phone tells you more than any dial photo. Set the watch down, hold the mic close, and read the number. You want 28,800 vph, which is 8 beats per second. Chinese automatic movements in cheap copies sit at 21,600, and the sweep looks slightly slower once you know what to look for. Beyond that, hack the seconds and check that the hand stops dead. Wind it and feel for smooth resistance rather than a sandy grind. Give the rotor a flick. A quality movement turns with a soft whir, not a rattle. If you can see the back through a display case, read the jewel count and the caliber engraving, then compare it to the reference you identified at the start.
Five-minute checklist
- Loupe the dial printing, especially the brand name.
- Study the subdial hand for length and taper.
- Tilt the dial and watch how the finish sweeps.
- Read the caseback: reference, serial, engraving depth.
- Measure the beat rate with an app.
- Weigh it in your hand. Gold feels dense; plated steel does not.
The part that does not change
None of this turns a copy into an IWC. A replica has no factory service, no warranty, and no resale value, and selling one as genuine is fraud. I mention it because this search term pulls in two different crowds: people who already own a watch and want to know what they have, and people shopping. Both need the same checklist. Only one of them needs the warning.
