Editor's Notes

The story of IWC SCHAFFHAUSEN's 'Portugieser' style began in 1939, when two Portuguese merchants asked for a large wristwatch that was as accurate as the chronometer on a ship. This chronograph version is crafted from polished 18-karat gold that complements the classic dark-brown alligator strap. It's powered by a precise IWC-manufactured calibre 69355 automatic movement that you can see working through the case back and has a small second sub-dial and 30-minute counter.
