Overview
The IWC Portugieser Chronograph reference IW371604 presents the enduring Portugieser silhouette in a 41 mm stainless steel case paired with a clean silver dial. Powered by the manufacture Calibre 69355, it represents IWC's commitment to bringing in-house chronograph movements to one of its most storied lines. The result is a watch that balances dressy restraint with genuine horological substance.
History
The Portugieser line traces its origins to the late 1930s, when IWC produced large-cased pocket-watch-movement wristwatches at the request of Portuguese merchants — a heritage that established the collection's characteristic clean dials and generous case dimensions. The chronograph variant has been a cornerstone of the Portugieser family for decades, evolving through successive calibres. The IW371604, introduced around 2020, marked a significant step by adopting the Calibre 69355, an in-house column-wheel flyback-capable movement developed entirely within IWC's Schaffhausen manufacture. Collectors regard this generation as a meaningful upgrade over earlier iterations that relied on ébauche-based movements.
Notable points
- Calibre 69355 is an in-house IWC movement featuring a column wheel and a flyback function, a notable advancement for the Portugieser Chronograph line.
- The 41 mm stainless steel case sits at a versatile size that honours the Portugieser's tradition of larger, legible proportions while remaining wrist-friendly.
- The silver dial follows the collection's hallmark minimalism: applied indices, a railway-track minute chapter, and subsidiary registers that keep the layout uncluttered.
- Introduced in 2020, the IW371604 is part of a broader Portugieser refresh that brought in-house movements across several references in the family.
- The combination of a dress-watch aesthetic with a genuine manufacture chronograph movement makes this reference a frequent point of discussion among IWC collectors.
