ZEITGEIST COMBINED WITH TRADITION

Since its debut in 2004, the Portuguese Automatic with date display has become one of the most successful Portuguese models ever to come from Schaffhausen. The balanced dial design, with its appliquéd Arabic numerals, railway track-style chapter ring and slender feuille hands, retains the classic appeal of the legendary original Portuguese, first manufactured in the 1930s. Its spiritual roots reach all the way back to the voyages of discovery undertaken by the Portuguese seafarers. The voluminous IWC-manufactured 51011 calibre integrates all the finest features ever to grace an automatic movement, such as the highly efficient Pellaton winding system and a seven-day power reserve. Since 2010, the Portuguese Automatic’s 42.3 millimetre case has been available in warm-toned, 18-carat red gold. The appliqués on the silver-plated dial are likewise made of red gold. The steel model with its silver-plated dial (like the earlier steel versions) was fitted with rose-gold-plated hands, numerals and hour indices: luxury befitting of a watch model so much in demand. The Portuguese Automatic in 18-carat white gold and the other steel models complete the collection.

51011 Calibre

Click on a component of the calibre below to learn more

  • Indexless screw balance with precision-adjustment cams and Breguet spiral, seconds stopped by pulling out the crown.

  • Shock absorption (Incabloc), together with the spring-mounted rotor bridge, provides effective protection against vibrations and impacts of the most sensitive parts.

  • Large rotor for bidirectional winding, can be dismantled for servicing simply by undoing one screw and a retaining bar.

  • Pawl-winding wheel, which transmits the movement of the two pawls through intermediate wheels to the barrel.

  • Set into the rotor is a 18-carat yellow gold medallion with the IWC stamp, "Probus Scafusia."

  • Pellaton automatic winding via two highly efficient, bearing-mounted moving pawls, which turn the winding wheel (yellow) and build up a useful power reserve of 168 hours (seven days). When the watch has wound down this far, the movement is stopped mechanically. The energy remaining in the barrel, which would be sufficient for another 24 hours' running, is not used because this prevents the decreasing end torque in the spring from affecting the watch's accuracy.
