A fake Portofino Small Seconds 33 is only convincing when three things line up: a true 33 mm case proportion, a small-seconds subdial sitting correctly at 6 o'clock, and clean printing on an otherwise plain dial. My pick for most buyers is the mid-tier first copy with an off-the-shelf Japanese automatic, a domed sapphire crystal, and a leather strap with a correctly shaped buckle. It gets the details people actually see right, and it avoids paying extra for a copied in-house movement that few shops will service. Everything below is judged on four criteria: case size and thickness, dial and subdial execution, crystal and caseback finish, and strap and buckle quality.

Fake IWC Portofino Small Seconds 33: Buyer's Guide

Design cues that define this model

The Portofino line is a dress watch family: thin bezel, uncluttered dial, slim profile, leather strap. In the 33 mm size class the watch is small by modern standards, which is exactly where replicas fail. Shrinking a 40 mm design on a computer does not shrink the printing, the hand thickness, or the curve of the lugs. Watches in this class typically carry applied markers, a subdial at six, and a signed crown. Check those three before you look at anything else.

  • Subdial centered at 6 o'clock, sized to leave a clean ring of dial around it.
  • Applied markers with a visible bevel instead of flat printed stickers.
  • Bezel thin enough that the dial, not the metal, dominates the view.

Criterion 1: Case size and thickness

Measure across the case at 2 to 4 o'clock, excluding the crown. A 33 mm watch should read as 33 mm, not 36 mm with a wide bezel. Thickness matters just as much: a small dress watch that sits more than roughly 10 mm tall will look like a puck under a cuff, and the caseback will not sit flat on the wrist.

Pros of a correct case

  • Lugs curve down toward the wrist, so the strap meets the case without a gap.
  • Crown sits proportional to the case, not oversized and not buried.
  • The watch disappears under a shirt cuff, which is the whole point of the model.

Cons of a wrong case

  • Oversized cases make the subdial look tiny and the markers look thin.
  • A thick case lifts the watch off the wrist and shows a shadow line at the lugs.
  • Sharp lug edges catch on sleeves and signal the build quality immediately.

Criterion 2: Dial, markers, and the small-seconds subdial

This is where a cheap fake falls apart at arm's length. Look at the subdial first: the hand should reach the printed track without overshooting it, and the subdial ring should be crisp rather than a smudged circle. Then look at the printing. Text on a genuine dial is sharp under magnification, sits level, and does not bleed into the surrounding finish.

Pros of a well-executed dial

  • Flat, even lacquer or opaline finish with no ripples near the markers.
  • Markers aligned to the minute track, all at the same height.
  • Subdial hand moves smoothly and sweeps, rather than ticking once per second.

Cons to watch for

  • Subdial placed slightly off center, which is obvious in photos and impossible to unsee.
  • Thick printed text that fills the space where thin text belongs.
  • Markers that sit crooked or reflect light at different angles from each other.

Criterion 3: Crystal, caseback, and strap hardware

The crystal changes how a dress watch reads in person. Sapphire with a light anti-reflective coating gives a clear, low-glare look; mineral glass picks up haze and scratches within months. On the back, engraving should be deep and legible rather than laser-etched and shallow. The strap is the part you touch most, so check stitching density, edge paint, and the thickness of the buckle tang.

Pros of good finishing here

  • Crystal sits slightly domed above the bezel, matching the vintage feel of the line.
  • Caseback engraving is crisp at an angle, not just straight on.
  • Buckle tang fits the holes without forcing, and the strap bends without cracking.

Cons of cutting corners

  • Mineral glass shows swirl marks and dulls the dial within weeks of daily wear.
  • Shallow engraving looks painted on and disappears in low light.
  • Stiff, plastic-feeling leather creases at the lugs and never breaks in.

Option 1: Budget quartz builds

The cheapest versions use a quartz movement, which keeps the case thin and the price low. They can look acceptable in photos and are fine as a costume piece.

Pros

  • Lowest cost, so replacing one after damage is painless.
  • Thin case that suits a 33 mm dress watch better than some automatics.
  • No winding, no service interval, accurate timekeeping.

Cons

  • The small-seconds hand ticks in one-second jumps, which is the most obvious tell on the wrist.
  • Dial printing and marker alignment are usually the weakest of any tier.
  • Strap and buckle hardware are typically the first parts to fail.

Use case: a one-off formal event where the watch is seen from a distance and worn for a few hours.

Option 2: Mid-tier first copy with a Japanese automatic (top pick)

This tier uses a proven off-the-shelf automatic movement in a correctly proportioned case, with a sapphire crystal and a leather strap that feels like leather. It is the balance point for most buyers.

Pros

  • Sweeping small-seconds hand, which fixes the single biggest visual gap.
  • Movements are common enough that any local watchmaker can regulate or replace one.
  • Better dial printing and marker alignment than budget builds.
  • Sapphire crystal keeps the dial clear over years of wear.

Cons

  • Costs more than a quartz build, and quality still varies between sellers.
  • Case thickness can creep up because of the automatic movement.
  • Not serviceable by the original brand, and resale value is effectively zero.

Use case: regular wear in an office or dress setting where the watch is seen up close by people who know watches.

Option 3: High-tier builds with copied movements

The top replica tier mimics the genuine movement architecture, including decoration and rotor style. It is the closest thing to the real watch in feel and the hardest to live with.

Pros

  • Case thickness and caseback depth match the original more closely.
  • Decoration and engraving look right when the watch is handled.
  • Best dial finishing of the three tiers, with sharper applied markers.

Cons

  • Highest price, often close to a well-known entry-level automatic from a legitimate brand.
  • Copied movements are difficult to service and parts are not standardized.
  • A repair can cost more than the watch, with no warranty path.

Use case: collectors who already own a service contact and want the closest visual match, not a daily wearer.

Legal and practical checks before you buy

Counterfeit watches carry real risk in the United States. Importing counterfeit merchandise is prohibited, shipments can be seized, and sellers who traffic in it face civil and criminal exposure. A replica also comes with no brand servicing, no warranty, and no resale market. Treat it as a private purchase for personal wear, never as an investment, and never present it as genuine. Ask the seller for in-hand photos of the exact unit, confirm the movement type in writing, and check the return policy before paying. If the listing uses stolen official photography, walk away.
