The IWC Portugieser Chronograph (ref. IW371626) refines a modern icon with a precious metal upgrade and a striking new dial. Introduced in 2024, this reference reimagines the longstanding 3714 aesthetic with the appeal of white gold and an uncommon ice-blue dial – a pairing that adds subtle tension to the line’s typically conservative design language.

The 41mm case is rendered in 18ct white gold, framing a sunburst blue dial that shifts tone with the light while retaining the signature vertical date-free symmetry and railroad-style minute track. A sapphire caseback reveals the in-house calibre 69355 – a column-wheel chronograph movement offering a 46-hour power reserve and 30m water-resistance. The upgraded automatic calibre replaces the Valjoux-based movement used in earlier Portugieser Chronographs, marking a notable step forward in both finishing and function. Combining precious metal construction with a rarely seen dial execution, the IW371626 sits at the confluence of sport and formal watchmaking. For collectors drawn to the Portugieser’s heritage but seeking a contemporary expression, this reference offers both pedigree and distinction.
