The short answer
Buy the original IWC Portofino Automatic 37 if you want a dress watch you can service, insure, hand down, and sell. Buy a replica only if you accept that you are getting a cosmetic object with no support behind it, and know that the Portofino is one of the hardest watches to copy convincingly. The design has no chronograph, no open dial, and no complication to hide behind. Everything is exposed: the curve of the leaf hands, the thickness of the case, the quality of the dial print. A careful buyer can spot a fake in under a minute with a loupe and a straight edge, and that is the single most useful fact in this guide.
What actually differs
Dial and printing
The original dial carries a fine sunray brush that moves from bright silver to near charcoal as the wrist rolls. Replicas tend to use a coarser brush or a stamped finish that reads flat grey from every angle. Under magnification the letterspacing of the brand name, the weight of the Schaffhausen line, and the crispness of the minute track are the tells. Fakes show ink spread, uneven serifs, and a minute track that fades toward the edges of the dial.

Hands and indices
Leaf shaped hands are expensive to make well. The original pair has a defined center ridge, polished bevels, and a precise curvature. Replicas use stamped hands that are flat on top, slightly too thick, or bent at the wrong point. Applied indices on the original are faceted and sit at a consistent height. On a fake they often look soft edged and sit proud of the dial by a fraction of a millimeter.
Case, crown, and crystal
The case measures 37mm across and sits roughly 9.4mm tall, which is the whole point of the model: it slides under a shirt cuff. Many replicas come in at 10.5mm or more, and that extra millimeter changes how the watch wears. The case is fully polished, so any inconsistency in the finishing shows under direct light. The crown engraving on a fake is shallow and the threading feels gritty. The sapphire crystal on the original has anti reflective coating on both faces, which gives a faint blue violet sheen and makes the glass almost disappear. Fakes usually have single sided coating or none, so reflections are stronger and the dial looks milky at an angle.
Caseback and strap
The solid caseback carries deep, crisp engraving. Fakes use shallow laser etching that catches light differently. Original straps are Santoni leather with a specific stitch density and a signed buckle; replicas ship with generic leather and a buckle whose engraving rubs away.
Movement
The genuine watch runs the 35111 calibre, a Sellita base with about 42 hours of power reserve at 28,800 vibrations per hour. Replicas typically use an Asian clone running at 21,600, so the seconds hand sweeps with a visible stutter, and the rotor is audible across a quiet room.
Numbers worth checking
- Case diameter: 37mm. Anything over 38mm is not this model.
- Case thickness: about 9.4mm. Measure it; this is the fastest single test.
- Lug width: 18mm.
- Water resistance: rated 3 bar. That is splash resistance, nothing more, on both original and replica.
- Power reserve: about 42 hours on the genuine movement.
- Beat rate: 28,800 vph. A timegrapher reading of 21,600 is a strong warning sign.
- Weight: the original head feels light for its size because the case is thin.
Pitfalls to avoid
- Importing a counterfeit is illegal in the United States. Customs can seize and destroy the parcel, and you have no recourse.
- Franken watches, meaning a genuine dial dropped into a fake case, are the hardest to identify and the worst value.
- No maker will service a counterfeit, and independent watchmakers often refuse because parts do not exist.
- Resale value is zero. The original holds a meaningful share of its cost, which offsets part of the purchase price over time.
- Water resistance claims on replicas are paperwork, not engineering. Do not swim in one.
- You cannot insure a counterfeit, so a theft or a drop is a total loss.
If you pass on the original
A pre owned Portofino 37 on leather is the closest thing to a bargain in this size, and it comes with a service history you can verify. If the design rather than the badge is what you want, look at the Nomos Tangente 38, the Longines Flagship Heritage, the Tudor 1926 in 36mm, the Grand Seiko SBGW231, or the Cartier Tank Must in large. Each is a real 36 to 38mm dress watch with factory support, and each costs less than a new Portofino while doing the same job on the wrist.
FAQ
Can a jeweler tell a fake Portofino 37 from the original?
Yes, usually in seconds, and almost always from the hands and the dial print before anything else is examined.
Is a replica Portofino 37 waterproof?
It may survive a hand wash. It is not rated for swimming, and the gaskets are not to the same standard as the original.
Do replicas use real Swiss movements?
Some sellers claim a Sellita or ETA base. Most watches in this category carry an Asian clone, and the beat rate reveals which one you have.
Does the 37mm case wear small?
It wears like a classic dress watch. On a wrist under seven inches it looks correct; on a larger wrist it reads formal and slightly vintage.
Is buying a counterfeit legal?
Buying inside the United States is a grey area. Importing one is not, and shipments are routinely seized.
