IWC Watch Portugieser Chronograph. IW371615. The Portugieser Chronographs from IWC Schaffhausen offer the wearer an impeccable tool in a robust practical design. Traditional manufacturing methods and a devotion to tried and tested techniques at the company’s facilities ensure precision and performance are consistently underpinned in every model, including this men’s 41mm timepiece. It presents the time on an unmissable green dial dressed in matching green sub counters for chronograph minutes and small seconds, two complications perfect for measuring elapsed time. Polished steel push pieces located at 2 and 4 o’clock on the IWC Portugieser Chronograph’s case facilitate easy operation over these functions. Maintaining the IWC Portugieser’s origins as a nautical precision instrument, this men’s chronograph watch is powered by the highly accurate Calibre 69355 which provides a useful 46 hour power reserve and can be admired through a sapphire crystal case back. A total of 194 hand assembled components make up this reliable mechanism, each one having been arranged with meticulous care by the hands of some of Switzerland’s most skilled craftsmen. The IWC Portugieser Mens watch continues to impress with a 30 metre water resistant rating and a stylish black alligator leather strap complete with a stainless steel folding buckle stamped with the iconic IWC Schaffhausen emblem.
