IWC Portofino Automatic Steel — Silver Dial | Ref. IW356517

The Portofino Automatic in 40 mm stainless steel represents IWC's most accessible entry into the collection's philosophy of Italian-inflected dress watchmaking. Where the larger Portofino references command attention through grand dimensions, this 40 mm variant achieves elegance through proportion: a profile of just 9.3 mm makes it one of the slimmest watches in the current IWC catalogue, capable of disappearing beneath a shirt cuff while retaining the visual authority of a serious timepiece.

Calibre 35111 is a reliable and well-established automatic movement developed in partnership with Jaeger-LeCoultre, providing date display, centre seconds, and approximately 42 hours of power reserve from a single mainspring barrel. The silver-plated dial is organised around applied hour markers and dauphine-style hands, both of which maintain the Portofino's commitment to unambiguous legibility. The absence of a display caseback keeps the silhouette as clean as possible, consistent with the watch's character as a dress instrument rather than a showcase for mechanical spectacle.

A convex sapphire crystal with antireflective coating on both surfaces sits flush with the bezel in a manner that emphasises the watch's slim profile. The black alligator leather strap adds a note of formality that suits the silver dial's clean presentation. At CHF 4,165, Ref. IW356517 offers genuine Swiss manufacture credentials, IWC's assured design language, and everyday wearability in a package that engages with the Portofino tradition without demanding the investment of the collection's more complex references.
