Portugieser Chronograph Steel White Dial 42mm

About the Model

The IWC Portugieser Chronograph (ref. IW371604) refines a modern classic with subtle upgrades and timeless aesthetics. Retaining the balanced proportions of the iconic 3714, this reference introduces a silver dial accented by applied rose-gold Arabic numerals and feuille hands – a warm, elegant contrast that lends depth to its understated design.

Housed in a 41mm stainless-steel case, the watch is powered by the in-house calibre 69355, an automatic chronograph movement with a 46-hour power reserve and column-wheel architecture visible through the sapphire display back. The vertical sub-dial layout remains intact, preserving the Portugieser’s clean symmetry, while water resistance is rated to 30m.

Originally introduced as part of IWC’s 150th Anniversary line in 2018 before joining the core collection, the ref. IW371604 bridges heritage and technical refinement. With its sculpted lines, updated mechanics, and versatile palette, it offers a contemporary take on one of IWC’s most recognisable designs.Read More
