Overview

The IWC Portugieser Automatic 40 (ref. IW358304) presents the storied Portugieser aesthetic in a 40.4 mm stainless steel case that sits comfortably on a wider range of wrists than its larger siblings. The silver dial upholds the line's tradition of clean, legible layouts, while the in-house Calibre 82200 provides a contemporary mechanical foundation. Introduced in 2020, it represents IWC's considered response to a collector appetite for a more wearable Portugieser format.

History

The Portugieser lineage traces back to the 1930s, when IWC produced oversized pocket-watch-movement wristwatches at the request of Portuguese merchants — a heritage that established the line's hallmark large-dial, clean-dial character. For decades the collection was anchored by 42 mm and larger references, making the arrival of the 40.4 mm Automatic 40 in 2020 a meaningful shift toward accessibility without sacrificing the line's formal DNA. The IW358304 has since become a reference point for collectors seeking a dress-oriented IWC that transitions naturally from business to evening wear.

Notable points

  • 40.4 mm stainless steel case strikes a balance between the Portugieser's traditionally generous proportions and modern wearability.
  • Silver dial continues the line's long-standing preference for restrained, high-contrast layouts with applied indices.
  • Calibre 82200 is an in-house automatic movement featuring a bidirectional rotor and a power reserve suited to everyday wear.
  • Introduced in 2020, the Automatic 40 marked IWC's deliberate move to broaden the Portugieser's appeal to a wider wrist-size demographic.
  • The dress-watch character of the reference is reinforced by slim case proportions and a dial architecture rooted in the collection's 1930s origins.
