Overview

The IWC Portofino Automatic ref. IW356502 is a 40 mm stainless steel dress watch presenting a silver dial within the long-running Portofino collection. Calibre 35110 powers the piece, offering reliable automatic winding in a movement sized to suit the line's slim, formal aesthetic. The result is a watch that sits comfortably at the intersection of Swiss engineering and Italian-inspired design.

History

The Portofino line takes its name from the picturesque Ligurian harbour town and has served as IWC's dedicated dress-watch family since the 1980s. The IW356502 was introduced in the early 2010s as part of a generation of Portofino references that standardised the case diameter at 40 mm, broadening the collection's appeal to modern wrist sizes. It has remained in production continuously, a testament to the enduring relevance of its understated formula. Among collectors, the reference is regarded as an accessible entry point into IWC's dress-watch heritage.

Notable points

  • 40 mm stainless steel case strikes a balance between classic dress-watch restraint and contemporary wearability.
  • Silver dial features a clean, uncluttered layout consistent with the Portofino line's Italian-resort aesthetic.
  • Calibre 35110 is an in-house-derived automatic movement offering a solid power reserve suited to everyday wear.
  • Slim case profile and absence of a date complication on certain dial variants reinforce the watch's purely formal character.
  • Continuous production since the early 2010s reflects sustained collector and retail demand for the reference.
