IWC Portugieser Automatic 2015

IWC Portugieser Automatic IW500701Thanks to its iconic design, IWC Portugieser Automatic is one of the best known models in the Portugieser collection.

Since its debut in 2000, the Portugieser Automatic has been equipped with one of the largest and most efficient automatic winding systems offered by any mechanical wristwatch in the premium class today. To mark the watch family’s 75th anniversary in 2015, the Portugieser Automatic has been equipped with the newly developed IWC-manufactured 52010 calibre.

With two barrels instead of just one, the IWC-manufactured 52010 movement now has a 7-day power reserve. And thanks to its ceramic components, the self-winding mechanism is practically wear-free.

The legendary bidirectional Pellaton winding system has been further improved: the pawls, automatic wheel and rotor bearing are now made of ceramic, giving the mechanism a special status in modern watchmaking technology.

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 Portugieser Automatic is water-resistant to 3 bar and available in two 18-carat red gold and three stainless-steel versions. The models with the 42.3-millimetre red gold cases are complemented by either a silver-plated or slate-coloured dial as well as solid gold appliqués.

In stainless steel, 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.

The Portugieser Automatic is supplied with a dark brown or black alligator leather strap which complements the dials. The large, ruggedly finished folding clasps are made of the same material as the case.
