Is your IWC Portofino
the real deal?

Look at the hands. The Portofino is a dress watch defined by slender feuille (leaf-shaped) hour and minute hands that taper to a fine point, paired with narrow applied indices on an exceptionally clean dial. Counterfeiters routinely get the hand shape and proportions wrong — the leaf is too fat, too stubby, or replaced with a plain baton — and the printing of IWC and SCHAFFHAUSEN loses its crispness under a loupe. Because the dial is so minimal, any error in hand shape, spacing, or symmetry stands out immediately.

Current Portofino Automatic 40mm models use IWC's 32000-calibre family — for example the calibre 32110, which runs at 28,800 vph, uses a bidirectional pawl winding system and silicon escapement components, and delivers roughly a 72-hour power reserve. Older Portofino Automatics used other bases, so verify the caliber against the specific reference. The key point for authentication is that a genuine movement is cleanly finished and IWC-signed; a fake hides a generic, undecorated caliber behind the case back or a solid back that shouldn't be there.

It depends on the reference. Many Portofino Automatic and Hand-Wound models have a sapphire display back that shows a decorated, IWC-signed movement; some references use a solid or engraved back instead. Know what your exact reference should have before you judge. If a model that is supposed to have an exhibition back instead shows a solid back — or a clumsy window over a plain movement with no IWC signature or Probus Scafusia hallmark — treat it as a red flag.

The Portofino Automatic is offered in 40mm and 34mm, the Chronograph in 42mm, and the Hand-Wound complication pieces (including the Eight Days) up to 45mm. The 40mm Automatic is the most common men's reference. Because the collection is a slim dress line, a genuine Portofino wears thin and refined; a bulky, tall case is a warning sign that a different, cheaper movement is inside.

A genuine IWC carries a serial number engraved on the case (often on the case back or between the lugs) and repeated on the warranty card and papers. The engraving should be crisp and evenly cut, and it should match the reference and the card exactly. IWC does not offer a public serial lookup, so the most reliable check is to contact IWC or an authorised dealer with the serial and reference. A mismatched, shallow, or acid-etched serial — or papers that don't match the watch — points to a fake or a married piece.

The moon phase is one of the harder details to counterfeit convincingly. Genuine Portofino moon phase models — such as the Hand-Wound Moon Phase with the in-house calibre 59800 and its moon display at 12 o'clock — use a cleanly printed moon disc with a precise aperture and correct proportions. Fakes tend to have a crude moon graphic, a misshapen aperture, or a disc that steps unnaturally instead of advancing smoothly. Combine the moon-phase check with the hand shape and movement inspection.

The Portofino Automatic in steel typically retails in the region of roughly $5,000-$7,000, the Chronograph a little higher, and gold or complicated Hand-Wound models well into five figures. On the pre-owned market, steel Portofino Automatics are among the more accessible ways into IWC ownership. Prices vary by reference and region, so treat these as ballpark figures — and treat a price far below the going rate as a red flag rather than a bargain.
