The IWC Portugieser Chronograph (ref. IW371625) refines one of the brand's most recognisable designs in a striking rose-gold and black configuration released in 2024. With its lean Arabic numerals, feuille hands, and vertical subdial layout, the Portugieser remains a paragon of balanced dial design – here elevated by the contrast of a deep black dial beneath rich gold casework.

Measuring 41mm, the rose-gold case houses IWC’s in-house calibre 69355, a column-wheel chronograph movement offering a 46-hour power reserve. One major update over its predecessor, the ref. 3714, is a sapphire caseback that reveals the Geneva stripes and intricate architecture within. Water resistance is rated to 30m, making this a watch best suited to formal settings. Chronograph controls retain the classic pump pusher design, lending just the right vintage tone to its modern mechanics.

This reference builds on the success of the 150th Anniversary foundation laid in 2018 while bringing the updated 3716 architecture to regular production. For collectors seeking the classic mid-century styling of the Portugieser with upgraded internals and precious-metal refinement, ref. IW371625 offers a compelling case.
