Overview

The IWC Portofino Automatic ref. IW356501 is a dress watch built around the brand's enduring Portofino design language — clean lines, a domed sapphire crystal, and a restrained black dial that prioritises legibility over decoration. At 40 mm in stainless steel, it occupies a versatile middle ground between understated elegance and everyday wearability. Calibre 35110 provides the mechanical foundation, offering a reliable automatic movement well suited to the watch's refined character.

History

The Portofino line takes its name from the picturesque Italian fishing village and has been a cornerstone of IWC's dress-watch offering since the 1980s. The IW356501 was introduced in the early 2010s as part of a generation of Portofino references that standardised the 40 mm case size, broadening the collection's appeal to a wider range of wrists. Its long production run reflects the enduring commercial and aesthetic success of the formula. Among collectors, the reference is regarded as an accessible entry point into IWC's dress-watch universe without sacrificing the brand's characteristic finishing standards.

Notable points

  • 40 mm stainless steel case strikes a balance between classic dress-watch restraint and modern proportions.
  • Black dial with applied hour markers and slim hands keeps the aesthetic deliberately uncluttered.
  • Calibre 35110 is an in-house-derived automatic movement with a power reserve suited to daily wear.
  • Domed sapphire crystal contributes to the watch's vintage-inflected, elegant profile.
  • A long-running reference since the early 2010s, reflecting consistent collector and retail demand.
