The IWC Portugieser with a 7 day power reserve is one of the brand’s most popular models. The harmoniously designed dial is unsurpassed and the inner components are now made of wear-resistant ceramic with two barrels which build up an incredible 7 day power reserve. The watch has a stainless steel case with a transparent sapphire glass case back through which the Swiss-made precision automatic movement can be admired. A black leather finishes this stunning IWC timepiece.
