Editor's Notes

Originally released in 1939, IWC SCHAFFHAUSEN's 'Portugieser' watch is as accurate and easy to read as marine chronometers. This polished stainless steel version is kept by the house's 69355-calibre movement that has a 46-hour power reserve and is visible through the exhibition case back. The silver-plated dial is meticulously arranged for clarity and features blue hands and numerals to complement the navy alligator strap.
