The IWC Portuguese Chronograph IW371401 represents one of the most iconic expressions of the Schaffhausen-based brand’s dedication to legibility, precision, and restrained elegance. Introduced in the early 2000s, this reference belongs to the broader Portuguese collection—named not after a national style, but after two Portuguese businessmen who, in the 1930s, requested a wristwatch with marine chronometer precision. The result was a line of oversized wristwatches housing pocket watch calibres. The IW371401 carries forward that lineage with a 40.9mm stainless steel case and a clean, symmetrical dial layout marked by Arabic numerals, feuille hands, and a recessed seconds subdial at 6 o’clock paired with a 30-minute counter at 12.
This watch is powered by the IWC Caliber 79350, a modified Valjoux 7750 base movement. IWC significantly reworked the architecture to improve aesthetics and reliability, removing the date and reconfiguring the chronograph layout to preserve dial balance. The result is a bicompax chronograph with a classical appeal, often praised for its slender profile relative to many other 7750-based watches. A domed sapphire crystal and polished bezel add to the refined look, while the vertical brushed case sides subtly reference the utilitarian origins of its forebears.
Among collectors and enthusiasts, the IW371401 holds lasting appeal due to its transitional role in the Portuguese line: it bridged traditional watchmaking values with modern chronograph practicality without overcomplicating the aesthetic. It also became a flagship piece for IWC at a time when the brand was expanding beyond its engineering-driven roots into more widely appreciated luxury design. As the first automatic chronograph in the Portuguese family, this reference helped solidify the collection as a core pillar of IWC’s modern catalogue.
