Portugieser Automatic 42, IW501701

This version features a stainless steel case with a diameter of 42.4 millimeters, a silver-plated dial, and gold-plated hands and appliques. The watch appears elegant and refined thanks to a thoroughly reworked case construction with a thinner casing ring and box-glass sapphire crystals on the front and the back. A highlight is the intricately crafted dial, which is manufactured in a complex process comprising 60 individual steps. The unusual optical depth is created by applying 15 layers of transparent lacquer, which is fine-ground and then polished to a high gloss finish. The subdials are milled into both the brass blank and the lacquer layer. A special printing process further enhances the three-dimensional effect. Finally, the appliques are individually mounted on the dial by hand. The Portugieser Automatic 42 is powered by the IWC-manufactured 52011 caliber, which is elaborately finished with circular graining and Geneva stripes. The Pellaton winding system is reinforced with virtually wear-free zirconium oxide ceramic components and builds up a power reserve of seven days (168 hours) in two barrels. The watch is fitted with a black alligator leather strap with a stainless steel folding clasp.
