In the late 1930s, these pocket watch-size nautical instruments inspired an unusual wristwatch: the Reference 325, based on a hunter pocket watch calibre, featured a simple chapter ring, Arabic numerals and slender feuille hands. The dial of the watch, which was later emblazoned with the name Portugieser, has remained virtually unchanged ever since. Its clear-cut, functional design looks every bit as fresh and contemporary as it did over 80 years ago. The Portugieser thus perfectly embodies the timeless modernity that distinguishes the IWC brand.
Now, for the first time, the new collection is entirely equipped with high-quality IWC-manufactured calibres. Even in its standard version, the popular Portugieser Chronograph is now fitted with the IWC-manufactured 69355 calibre and features a seethrough sapphire-glass back.
