*IWC "Two New Models Grace Portuguese Collection"

IWC the Portuguese Chronograph Classic



The new Portuguese Chronograph Classic (Ref. 3904) brings exceptional elegance and classically inspired design to this popular collection, though the redesigned watch has a surprisingly independent look. This third chronograph member of the Portuguese dynasty preserves the identity and cultural heritage of the legendary originals of the 1930s. The timepiece comes complete with appliquéd Arabic numerals, a railway-track-style chapter ring and slender feuille hands. An arched-edge front glass makes this slim beauty’s 42-millimetre diameter seem smaller than it is. The traditional type of glass used admirably sets off the language of form, lending a well-balanced and classical impression. Powering the Portuguese Chronograph Classic is an IWC-manufactured 89361 calibre, developed specifically to record time spans of up to 12 hours on a subdial. The result is as bold and easy to read as a clock face. The sapphire-glass back reveals the 89361 calibre and the rotor, resplendent in Geneva stripes. The Portuguese Chronograph Classic is available in 18-carat red gold or stainless steel, both with silver-plated or slate-coloured dial.
