Overview
The IWC Portugieser Chronograph reference IW371606 presents the enduring Portugieser silhouette in a 41 mm stainless steel case, distinguished by a deep blue dial. Introduced in 2020, it is powered by IWC's Calibre 69355, a column-wheel chronograph movement produced in-house. The reference continues the Portugieser line's long tradition of pairing clean, legible layouts with refined mechanical execution.
History
The Portugieser line traces its origins to the late 1930s, when IWC produced large-cased watches at the request of Portuguese merchants who wanted the precision of a pocket-watch movement in a wristwatch. The chronograph variant has been a cornerstone of the collection for decades, evolving through successive calibres while retaining the family's characteristic slim bezel and railway-track minute chapter ring. The IW371606, introduced in 2020, marked the arrival of the Calibre 69355 — IWC's own column-wheel, flyback-capable movement architecture — in the blue-dial Portugieser Chronograph. Among collectors, the blue dial variant is regarded as one of the more versatile expressions of the reference, pairing equally well with formal and casual wear.
