Since its debut in 2004, the Portugieser Automatic with date display has become one of the most successful Portugieser (Portuguese) models ever to come from Schaffhausen. The balanced dial design retains the classic appeal of the legendary original Portugieser first manufactured in the 1930s. From 2015, the Portugieser Automatic will be equipped with an IWC-manufactured movement from the new 52000-calibre family. The legendary Pellaton winding system has been further improved: the pawls, automatic wheel and rotor bearing are now made of extremely wear-resistant ceramic; and instead of one there are now two barrels, which build up an impressive 7-day power reserve. The ergonomically optimized strap horns ensure greater comfort even on slimmer wrists. The Portugieser Automatic is now available in two 18-carat red gold and three stainless-steel versions. The models with the 42.3-millimetre red gold cases have either a silver-plated or slate-coloured dial with solid gold appliqués. With the stainless-steel version, customers have the choice of one model with a black dial and silver-plated hands and appliqués or two models with silver-plated dials and either gold-plated or blue hands and appliqués. Now, thanks to the slimmed-down rotor, a glance through the transparent sapphire-glass back reveals even more details of the new IWC-manufactured 52010-calibre, such as the black ceramic pawls in the winding system or the Geneva stripe decoration.
