The Portugieser Automatic is itself an iconic timepiece in the prestigious Portugieser line that is celebrating its 75th anniversary in 2015. This model is well known for its iconic design and exceptional power reserve of up to 7 days. Unveiled at SIHH 2015, the latest Portugieser Automatic model houses the newly developed IWC-manufactured 52010 calibre and optimized strap horns. The dial, which is famous for its balanced design, remains unchanged.
The white- or black-coloured zirconium oxide reduces abrasion to virtually zero. The indexless balance has an increased frequency of 4 hertz (28,800 beats per hour). Combined with the Breguet spring, bent into shape using traditional techniques, this guarantees even greater precision.
The sapphire glass, which extends over nearly the entire back of the watch, provides a generous view of the 52010 calibre. In the course of overhauling the movement, IWC’s design engineers slimmed down the skeletonized rotor and modified the proportions of the golden “ProbusScafusia” medallion. As a result, it is easier to view the watch’s internal workings (the screw balance, new barrels and ceramic components), the bridges decorated with Geneva stripes and circular graining and the polished screws.
