The IWC Portugieser Chronograph ref. IW371615 is a 41 mm stainless-steel chronograph distinguished by its rich green dial, rhodium-plated hands and appliqués, and black alligator leather strap. Its open dial architecture follows the established Portugieser formula, with applied Arabic numerals, slim feuille hands, a chronograph minute counter at 12 o’clock and small seconds at 6 o’clock. A quarter-second scale around the flange reinforces the model’s instrument-inspired character while preserving the elegant proportions of the collection.
Inside is the IWC-manufactured calibre 69355, an automatic chronograph movement with classic column-wheel control and approximately 46 hours of power reserve. The movement is visible through the sapphire crystal caseback, allowing the mechanical construction of the chronograph to become part of the watch’s visual identity rather than remaining hidden behind a solid back.
Reference IW371615 is particularly distinctive within the Portugieser Chronograph family because the green dial gives the otherwise traditional steel-and-leather configuration a more contemporary character. It retains the clean symmetry and restrained case architecture that have defined the Portugieser Chronograph since the late 1990s, while offering a more expressive colour treatment for buyers who want the collection’s recognizable design without choosing a conventional silver or blue dial.
