Short answer
A watch sold as a "Portofino Small Seconds 33" replica is a small-case copy of IWC's Portofino line with a sub-dial at 6 o'clock. IWC's current catalog does not list a 33mm Portofino with small seconds. The Portofino Automatic 34 uses a 34mm case and center seconds. IWC's Portofino with small seconds is the hand-wound Hand-Wound Eight Days, 45mm, sub-dial at 6. Ask the seller for the reference number they copied. If they cannot name one, the watch is a mix of parts, not a copy of a single model.

Measure the case, do not trust the listing
Use a caliper across the bezel at 3 and 9, crown excluded. A case listed as 33mm will often measure 33.5mm to 34.5mm. Sellers use "33" and "34" for the same case, so the number in the title tells you little. Ask for the lug width. A wrong strap size costs $40 to $120 to fix. Ask for the thickness and compare it to the figure IWC publishes for the reference the seller names. A case over 11mm thick hides a taller movement and wears larger than a genuine small Portofino.

Check how the small seconds works
A real small seconds hand is driven by a fourth wheel under the dial. Cheap builds use three shortcuts: a glued decorative hand, a quartz module behind an automatic-looking rotor, and a center-seconds movement with the seconds hand moved to 6 by an extra gear. Ask for a 10 second video with the sub-dial in frame. Count the ticks. 6 per second means 21,600 vph. 8 means 28,800. 5 means 18,000. A quartz movement ticks once per second.

Dial, hands and printing
The Portofino dial uses applied markers, leaf hands, "IWC" under 12 and "SCHAFFHAUSEN" above 6. Check three points. First, the gap between the sub-dial and the 6 o'clock marker. Second, the thickness of the printed minute track. Third, whether the marker feet sit flush to the dial. On replicas the "SCHAFFHAUSEN" line runs wide, the sub-dial sits off center, and the hands have flat tops instead of faceted ones. Compare photos at 3x zoom against IWC's product images for the named reference.
Crystal, crown and caseback
Genuine Portofino uses sapphire with anti-reflective coating on both faces. Under angled light a genuine crystal shows a faint blue tint on both sides. Single-side coating shows tint on one face only. The crown on a 33mm to 34mm Portofino is about 4mm wide and pulls with a firm click. Caseback engraving on replicas is laser etched and looks grey under a loupe. Genuine engraving has sharper edges. IWC rates the 34mm Portofino Automatic at 3 bar. Do not swim with a replica and do not trust a printed depth rating.
Strap and buckle
Genuine straps are alligator on a steel pin buckle. Replica straps are stamped calf with a printed grain. Check the stitch pitch and the buckle tongue thickness. Plan on a replacement strap in the correct lug width.
Movement and rate
Most replicas in this size carry a Chinese automatic, a Miyota copy or a Seagull. Ask for the movement name. No-name movements cannot be serviced by a local watchmaker for less than the price of the watch. Rate test: set the watch against a phone clock, wait 24 hours, compare. Plus or minus 20 seconds a day is normal for this class. Over 60 seconds means a regulation or a return.
Price and paperwork
Asking prices for small-case Portofino replicas run from about $90 to $350. Above $350 you pay for case finish and a better strap, not a better movement. Boxes and papers add no value on a replica. A card with a serial that claims to match an IWC database is printed, not issued.
Legal note
US Customs can seize watches that carry a registered trademark without authorization. Trafficking in counterfeit goods is a federal offense in the US. Import risk and resale risk are separate from the risk of a bad watch.
Ask the seller these questions
- Which IWC reference did you copy?
- What is the measured case diameter and thickness?
- What is the lug width?
- Is the small seconds driven by the movement or decorative?
- What movement is inside, and what is its beat rate?
- Can you send a 10 second video with the sub-dial visible?
- Does the crystal have coating on one face or two?
